ASSESSMENT OF WATER LOSS  IN WATER SUPPLY NETWORK  A CASE OF DEBRE MARKOS TOWN
Creators: name: BY  MEBET ADMASS  DINKU
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Problems  in  provision  of  adequate  water  supply  to  the  rapidly  growing  urban
population  in  developing  cities  are  increasing  dramatically.  As  a-result  demand  for
additional water  sources  and  infrastructure  is  growing.  Moreover,  nearly  50%  of  the
water produced  is  lost at different  levels of the distribution system  before  reaching the
consumers.  Debre Markos  is  one of the developing cities suffering  a high shortage of
water as well as  high water  loss.  Both financial and  technical constraints are  the main
bottlenecks  that hamper the city  to  satisfy the highly growing  needs of  its  residents  .
Quantifying  and  characterizing water  loss  and  leakage  in  a city water  supply system
is  by  its  nature  a  complex  task.  Leakage  identification  needs  detailed  field
investigation  sometimes  using  sophisticated  equipment.  In  this  study,  an  attempt  is
made  to  evaluate  both  the  water  loss  and  economic  level  of  leakage  with  the
available primary and secondary data.
The focus of this study  is  to  assess  the  total water loss  in  the distribution  network and
determine  ELL.  Water  production  that  is  only  available  for  the  entire  city  and  the
water consumption as  aggregated  from  individual customer meter  readings was  used to  evaluate the total water  loss at  city  level.
Pressure  readings  have  been  taken  at  different  elevations  during  the  24-hour
durations  and  an  average  working  pressure was  fixed  for  the  determination  of  real
losses  in  the distribution  system.
Meter tests  of enough  samples  (according  to  IWA  recommendation) from  each  brand
that  were  installed  for  the  customers  were  conducted  to  quantify  the  water  loss ELL was determined  for the  system  using ECONOLEAK model.
Finally,  a methodology  is  suggested  to  better  identify  the  loss,  and  remedial  actions
to  be  taken  by  the  water  supply  service  office  to  reduce  water  loss.

description: Energy demand  is  greatly  increasing  in  the  country.  Developing  hydropower
plants  to  satisfy  the  energy demand  needs due attention  .The  newly  planed
and existing  hydropower plants have to  be used effectively.
One  way  of  using  waterpower  plants  effectively  is  managing  the  water
reservoir  in  the way that the maximum  possible energy can  be generated.  In
this  study  Melka  Wakana  Reservoir  is  Modeled  by  HEC-5  Reservoir
Simulation Model.
The  necessary  hydro-meteorological  data  have  been  collected  and
analyzed. The  reservoir evaporation  has  been  estimated  using Aerodynamic
and  Pan  Evaporation  methods. The  correlation  between  annual  runoff data,
from  gauging  stations on  the main  river,  and  annual areal  rainfall  has tested
using  regression  analysis.  Monthly  runoff data  (reservoir  inflow)  of  36  years
has  been  prepared  and  used  during  reservoir  simulation  by  HEC-5  model. The model  has  been  calibrated  and  verified  before  detail  simulation done  in
this study.
In  order  to  get  the  initial  guide  curve  one  of  optimization  techniques,
Dynamic Programming,  has  been  used. This  initial  curve  has  been  used  as
starting guide curve during detail  reservoir simulation using monthly reservoir

description: In order to better determine the large-scale 3D-structure of magnetic fields in spiral galaxies we present a Faraday rotation analysis of the edge-on spiral galaxy NGC 5775. Deep radio-continuum observations in total power and linear polarization were performed at 8.46 GHz with the VLA and the 100-m Effelsberg telescope. They were analyzed together with archival 4.86 and 1.49 GHz VLA-data. We thus can derive rotation measures from a comparison of three frequencies and determine the intrinsic magnetic field structure. A very extended halo is detected in NGC 5775, with magnetic field lines forming an X-shaped structure. Close to the galactic disk the magnetic field is plane-parallel. The scaleheights of the radio emission esimated for NGC 5775 are comaprable with other galaxies. The rotation measure distribution varies smoothly on both sides along the major axis from positive to negative values. From the derived distribution of rotation measures and the plane-parallel intrinsic magnetic field orientation along the galactic midplane we conclude that NGC 5775 has an 'even axisymmetric' large-scale magnetic field configuration in the disk as generated by an αΩ-dynamo which is accompanied by a quadrupolar poloidal field. The magnetic field lines of the plane-parallel component are pointing 'outwards'. The observed X-shaped halo magnetic field, however, cannot be explained by the action of the disk's mean-field dynamo alone. It is probably due to the influence of the galactic wind together with the dynamo action.

description: Introduction: Few studies including contradictory results have addressed the acute effects of the 11+ on motor performance, indicating a potentially reduced applicability of the program for warming up before competitions. This study aims to compare the acute effects of a soccer-specific warm-up (Football+) and the 11+ on motor performance. Materials and methods: Thirty-eight volunteer collegiate players (22 males; age = 21.1±1.9 years, height = 1.81± 0.06 m, weight = 73.4± 9.5 kg; 16 females; age = 21.3±1.5 years; height = 1.71± 0.07 m, weight = 67.8± 8.5 kg) underwent the 11+ and the Football+ in a randomized crossover design with a one-week washout. The Football+ starts with a self-estimated 40–50 percent running, followed by dynamic stretching of the hip muscles, shoulder contact, controlled lunge, Copenhagen exercise, and modified Nordic hamstring exercise. The second part involves roughly intensive small-sided games, followed by plyometric and anaerobic exercises in the third part. The warm ups’ effects on performance were determined by a linear sprinting test (20 m), countermovement jump performance (CMJ), Illinois agility (IA), and dribbling speed (DS) tests. Within-subject differences were reported as the means and SD. Pairwise t tests at the significance level of p<0.05 were used to calculate the significant differences. Results: Overall, except for the CMJ (mean = -0.43±3.20 cm, p = 0.21, d = -0.13), significant differences for the 20 m sprint (mean = 0.04±0.10 s, p = 0.005, d = 0.42), IA (mean = 0.65±0.45 s, p = 0.01, d = 1.43), and DS (mean = 0.60±1.58 s, p = 0.012, d = 0.38) were observed. In females, significant differences observed only for IA (mean difference = 0.52±0.42 s, p<0.001, d = 1.24) and DS (mean difference = 1.29±1,77 s, p = 0.005, d = 0.73), with the Football+ showing superiority. In males, significant differences were found only for 20 m sprinting (mean difference = 0.06±0.09, p = 0.005, d = 0.60) and IA (mean difference = 0.74±0.46, p<0.001, d = 1.62), with the Football+ having superiority. Discussion: Although practicable for injury prevention, the 11+ may not optimize acute performance and prepare players for high-intensity physical tasks as well as a well-structured, roughly intensive warm-up. Further gender-specific studies should evaluate the long-term effects of the Football+ on performance and injury prevention.

description: The Sylvester-Gallai Theorem, stated as a problem by J. J. Sylvester in 1893, asserts that for any finite, noncollinear set of points on a plane, there exists a line passing through exactly two points of the set. First, it is shown that for the real plane, the theorem is constructively invalid. Then, a well-known classical proof is examined from a constructive standpoint, locating the nonconstructivities. Finally, a constructive version of the theorem is established for the plane; this reveals the hidden constructive content of the classical theorem. The constructive methods used are those proposed by Errett Bishop.

description: Recent full-sky maps of the Galaxy from the Fermi Gamma-Ray Space Telescope have revealed a diffuse component of emission towards the Galactic center and extending up to roughly +/-50 degrees in latitude. This Fermi "haze" is the inverse Compton emission generated by the same electrons which generate the microwave synchrotron haze at WMAP wavelengths. The gamma-ray haze has two distinct characteristics: the spectrum is significantly harder than emission elsewhere in the Galaxy and the morphology is elongated in latitude with respect to longitude with an axis ratio ~2. If these electrons are generated through annihilations of dark matter particles in the Galactic halo, this morphology is difficult to realize with a standard spherical halo and isotropic cosmic-ray diffusion. However, we show that anisotropic diffusion along ordered magnetic field lines towards the center of the Galaxy coupled with a prolate dark matter halo can easily yield the required morphology without making unrealistic assumptions about diffusion parameters. Furthermore, a Sommerfeld enhancement to the self annihilation cross-section of ~30 yields a good fit to the morphology, amplitude, and spectrum of both the gamma-ray and microwave haze. The model is also consistent with local cosmic-ray measurements as well as CMB constraints.

We introduce the concepts of ac-dc local voltage and four point impedance in an electronic system driven by ac fields. We discuss the properties of the different components of these quantities in a simple model of a quantum pump, where two ac voltages oscillating with a phase lag are applied at the walls of a quantum dot.

description: As communication and trust are both linked with safety, this paper aims to investigate their contribution to aviation maintenance incidents and accidents. For this purpose, the content analysis method is used to investigate whether trust and communication factors were present in aviation maintenance occurrences. Content analysis is used as a qualitative and quantitative tool. For the data analysis, apart from direct investigation for keywords throughout the material for analysis (aviation accident/incident reports with maintenance involvement), a survey tool was also employed. The items of this survey tool (Communication and Trust Question Set) were used to filter the reports’ text to indirectly identify the two factors under examination (communication and trust). As a qualitative tool, the content analysis yielded results via mapping and narrative techniques. As a quantitative tool, results were obtained and reported with the help of descriptive statistics (counts, frequencies). The results indicated that elements of trust and communication are indirectly detectable in aviation maintenance occurrences. Both ineffective communication and lack of trust were identified as a key accident/incident causal condition. Interpersonal trust is recommended to be included in the implementation requirements of any communication system. The limitations associated with the difference in the structure and consistency of the examined material are also discussed.

Structural, stratigraphic and temporal constraints of gold mineralization in the Bigar Hill deposit, Timok region, Serbia
Creators: name: Zivanovic, Jelena
Publisher: name: University of British Columbia
Year: 2019

description: The Timok Magmatic Complex (TMC) is a well-endowed mineral district in Serbia that hosts world-class Cu-Au porphyry (Majdanpek, Veliki Krivelj, Borska Reka) and high-sulfidation deposits (Bor, Čukaru Peki). Recent exploration activities on the northwestern margin of the TMC have led to the discovery of the Bigar Hill sediment-hosted disseminated gold deposit (SHDG). It represents a previously unrecognized style of gold mineralization within the TMC and the Cretaceous metallogenic province of the western Tethyan orogenic belt - although they share many characteristics with the Carlin-type and distal disseminated gold deposits of Nevada, US. Gold distribution at Bigar Hill and associated hydrothermal mineralogical, geochemical and stable isotope alteration features were examined to reconstruct the structural and stratigraphic controls on hydrothermal fluid flow. The Bigar Hill stratigraphy encompasses Late Jurassic to Early Cretaceous limestone unconformably overlain by a calcareous clastic sedimentary sequence (unit S1). Late Cretaceous volcanic detritus-rich sandstone package (unit S2) unconformably overlies unit S1. Primary sparry carbonate cement, mainly ferroan calcite is characteristic features of both S1 and S2 units. Marl lies conformably over the S2 unit, and the andesitic sill intruded it. Gold mineralization is principally stratabound, located along two stratigraphic contacts. The contact zone between units S1 and S2 is a major mineralized horizon. The other mineralized corridor lies along the unconformable contact between limestone and the S1 siliciclastic rocks. Acidic hydrothermal fluids likely exploited the enhanced porosity and permeability of preserved weathering crusts, brecciated zones, and karst along the unconformities, further creating secondary porosity by dissolving host rock carbonate cement. Although stratigraphic features are considered highly influential on the spatial distribution of ore, the regional structural framework and syn-mineralization faults reactivations are thought to be necessary to allow mineralizing fluids to permeate favorable stratigraphic horizons. A 3D spatial analysis of stratigraphic contacts and changes in the thickness of sedimentary packages suggests that the controls of the ore body geometry are previously unrecognized sub-vertical structures that channeled upwelling metal-bearing fluids. Fluids then spread laterally along the contact zones between the sedimentary packages. Two recognized structural trends, NW and NE match the major gold mineralization trends.

description: This article provides an in-depth look at hadron high energy scattering by using gravity dual descriptions of strongly coupled gauge theories. Just like deeply inelastic scattering (DIS) and deeply virtual Compton scattering (DVCS) serve as clean experimental probes into non-perturbative internal structure of hadrons, elastic scattering amplitude of a hadron and a (virtual) "photon" in gravity dual can be exploited as a theoretical probe. Since the scattering amplitude at sufficiently high energy (small Bjorken x) is dominated by parton contributions (= Pomeron contributions) even in strong coupling regime, there is a chance to learn a lesson for generalized parton distribution (GPD) by using gravity dual models. We begin with refining derivation of Brower-Polchinski-Strassler-Tan (BPST) Pomeron kernel in gravity dual, paying particular attention to the role played by complex spin variable j. The BPST Pomeron on warped spacetime consists of a Kaluza-Klein tower of 4D Pomerons with non-linear trajectories, and we clarify the relation between Pomeron couplings and Pomeron form factor. We emphasize that the saddle point value j^* of the scattering amplitude in the complex j-plane representation is a very important concept in understanding qualitative behavior of the scattering amplitude. The total Pomeron contribution to the scattering is decomposed into the saddle point contribution and at most a finite number of pole contributions, and when the pole contributions are absent (which we call saddle point phase), kinematical variable (q,x,t) dependence of ln (1/q) evolution and ln(1/x) evolution parameters gamma_eff. and lambda_eff. in DIS and t-slope parameter B of DVCS in HERA experiment are all reproduced qualitatively in gravity dual.

description: Background: Previous studies have demonstrated that shift work can be significantly associated with adverse effects on liver function. However, the association between shift work and alkaline phosphatase (ALP) enzyme as a well-known biomarker of liver disease has been undefined. Methods: This cross-sectional study was conducted on a total number of 6,475 eligible oil refinery workers. According to shift work schedules, the participants divided to the following groups: 12-hr rotating night (n = 2,630) and 12-hr fixed day (n = 3845). The Spearman’s correlation and logistic regression were applied to assess the association between shift work and ALP. Results: We found significantly higher levels of ALP in 12-hr rotating night compared to 12-hr fixed-day shift work groups (196.2 ± 52.1 versus 191.5 ± 53.4). According to quartile (Q) logistic regression adjusted by significant variables between study group (age, body mass index, fasting blood sugar, and total cholesterol), the odds ratio and 95% confidence interval of high (Q2–Conclusions: This study indicated that 12-hr rotating night shift work may be associated with higher levels of ALP. More studies are needed to confirm our findings.

Assessment of Cause of Water Level Change  of Lake Kivu and  its  impact at downstream
Creators: name: Agabe Sam
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: The Kivu  Lake  level  is subjected  to  high fluctuations during  the  recent years.
The  aim  of  this  research  was  to  identify  the  causes  for  the  fluctuations  in  Lake
Level.  SWAT  model was  used  to  generate  water  balance  components  of  Lake
catchment.
The  results,  using  the  reference  period  1976  to  1990,  indicate  that  the  mean
annual  rainfall  over  the  lake  is  1266 mm  and  the mean  annual evaporation  from
the  lake  is  583 mm. When  compared with  lake  level  changes,  there  is  imbalance
of  21 %.  Adding  this  amount  to  the  calculated  evaporation,  it  was  possible  to
reconstruct  the  inflow  variation  into  the  Lake  from  1976  to  1990 and  the water
balance  of  the  lake.  Sensitivity  analysis  shows  that  the  discrepancy  in  the
balance  is  most  likely due to water abstraction  from  the  lake  as  some of water  is
used for domestic supply around the  lake and minor abstracts In  this  research,  the water  balance  of  Lake  Kivu  is  carried  out  using  the  SWAT
rainfall  runoff  model.  The  inflow  from  the  catchment  into  the  lake  has  been
generated  using  SWAT  model.  Evaporation  is  estimated  using  Penman  formula.
Rainfall  over  the  lake  is  estimated  from  the  catchment  rainfall  employing  the two
classes  'A'  gauging  stations around  the  lake as weather generating stations to  fill
the gaps  in the other rain stations.
Finally the main cause for  high  Lake  level fluctuation  is  found  to  be  the  rainfall
variability analyzed with  hydrological components  in  their variability trends
especially  in  the second  rainy season  in October,  November and December  ,

description: We present a microscopic theory of cross-correlated noise processes, starting from a Hamiltonian system-reservoir description. In the proposed model, the system is nonlinearly coupled to a reservoir composed of harmonic oscillators, which in turn is driven by an external fluctuating force. We show that the resultant Langevin equation derived from the composite system (system+reservoir+external modulation) contains the essential features of cross-correlated noise processes.

Adipose-derived stem cells improve tissue quality in a murine model of delayed wound healing
Creators: name: Forbes, Diana
Publisher: name: University of British Columbia
Year: 2019

description: Wound repair and regeneration is a multidisciplinary field of research with considerable potential value to the management of deep and large cutaneous injuries such as ulcers caused by pressure, venous and arterial insufficiency, and diabetes. These injuries lack an appropriate tissue scaffold and pro-healing cells making them difficult to heal. An ideal therapy is one that would restore both the essential matrix and cellular components that are lacking in these wounds to expedite healing. In this study, we used a novel liquid dermal scaffold capable of gelation in vivo to show that it is biocompatible with adipose derived cells. Using a validated method of wound splinting in an impaired-healing murine model we showed that wounds treated with adipose derived stem cells and the liquid scaffold had improved epithelialization, angiogenesis, and collagen content. The addition of adipose derived cells showed significantly increased expressions of essential growth factors: vascular endothelial factor (VEGF) and hepatocyte growth factor (HGF) in vivo and that these cells are detectable in the neodermis after wound closure. This liquid dermal scaffold with cells can be considered as a feasible future strategy for the management of complex or deep wounds that are otherwise lacking the appropriate cellular matrix necessary for healing.

description: We found that solar neutrinos with energy of about 10 Mev have perihelion effect, and protonswith energy above Gev of AMS-02 also have perihelion effect, so it is believed that solar energyproduces cosmic rays with energy above Gev. We propose a neutrino collision model for theorigin of cosmic rays. This model can reasonably explain the problem that the proton flow incosmic rays is much greater than the electron flow.
HYDROPOWER DEVELOPMENT POTENTIAL AND OPTIMUM OPTION IN GIBA RIVER BASIN
Creators: name: GAnania Mehari Negussie
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2004

description: The Ghiba river basin  in Tigray regional state,  North  Ethiopia,  has catchment
area of 5163km2,
the  length of  the main water course  is 236.4km, with a total
fall  of  2030m.  The  average  annual  rainfall  over  the  basin  is  665.5mm  and
annual  runoff volume of  1372milliom m3.
There  are eleven  storage  sites and
9  cascades  planned  (identified)  in  the  river  based  on  various  established
criteria:  head,  discharge  (reservoir  volume),  geology,  etc.  The  potential
storage  sites  are:  (1)  Suluh,  (2)  Genfel-1,  (3)  Genfel-2,  (4)  Genfel-3,  (5)
Genfel-4,  (6) Genfel-5,  (7) Agulae,  (8) Meskila-1,  (9) Meskila-2,  (10) Meskila-
3  and  (11)  Ghiba.  All  the  cascades  are  located  on  the  main  rivers
downstream  of  all  the  storage  sites  with  the  first  cascade  being  a  dam
scheme.  The  objective  of  this  study  is  to  estimate  hydropower  potential  at
each  site of  interest as well as  the whole basin, and  to  select an optional site
based  on  the  average  power  out  put  (Pm)  at  site  that  could  reach  selected
demand centres.
Hydropower  development  potential  of  the  Ghiba  basin  is  estimated.
Hydrologic study was  carried  out,  using  existing  discharge  data  recorded  at
the  gauging  stations  available  for  the  basin,  and  rainfall  gauging  stations  in
or nearby the  basin.  Due  to  significant missing data  in  rainfall  and  runoff,  as
well  as  poor matching  of  recorded  periods,  eleven  years  of  monthly  rainfall
and  concurrent  runoff  data  was  used.  The  missing  records  in  rainfall  data Hydropower Development  Potential and Optimum Option In Ghiba River Basin

The water resources potential,  at the  ungauged sites  (hydro sites) have  been
estimated  by applying the  relationships developed at gauge sites.
To  estimate  the  energy  potential  of  the  hydropower  sites  two  analytical
techniques  were  used  The  Flow  Duration  Curve  (FDC)  method  and  the
Sequential  Stream  Flow  Routing  (SSR) method.  Therefore,  the  total  annual
energy  potential  from  FDC  is170.27GWh  and  from  the  SSR  analysis  is
597  .179GWh.  In  addition,  822GWh  of  energy  could  be  harnessed  from  the
cascading systems.
All  the  hydro  sites are  assumed  to  be  connected  to  two  near by grid  centers
at Wukro and Mekelle. Selection of an optimal  site was  done by  ranking  site:
(1)  based  on  limited  criteria,  topography,  hydrology  and  proximity  to  load
centers,  (2)  based on the power out puts  reached  the demand centers. Thus,
the site with  the highest rank would  be  the optimal site.
This  study  thus  concludes  that,  the  total  hydro-energy  that  could  be
harnessed  from  the whole  basin  is  about  1419 GWh/  year  and  the  optimal
site, which should be  implemented first,  is the Ghiba storage  hydro site.

OPERATIONAL ANALYSIS OF THE CASCADED  WADECHA-BELBELA RESERVOIR SYSTEM  (A case  in Ada'a Liben woreda, Oromia region)
Creators: name: WAKENA TOTOBA OLANI
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: Wadecha-Belbela  reservoir  system  is  located  in  Oromia  Region,  East  Shoa
zone,  Adaa  Liben  woreda  serving  as  a  water  source  of  1600ha  irrigation
projects.  The  irrigation  system  under  the  reservoir  system  is  increasing
progressively during the past decades. The expansion of  irrigation  development
without the  knowledge of  the water source will  have  the outcome  of agricultural
yield  reduction  and  water  stress.  Inadequate  knowledge  on  operation  of  the
reservoir has  been  leading to  inefficient usage of stored water.
This  study  focuses  mainly  on  the  description  and  assessment  of  water
resources  of  the  woreda  based  on  climate,  land  and  water  information,
estimation  of  irrigation  water  requirements  of  the  reservoir  system  irrigation
projects,  and  operational  analysis  of  the  reservoir  system  by  the  application  of
reservoir system simulation model  (HEC-ResSim). Nine years  of meteorological  data were  used  to  simulate  the Wadecha-Belbela
reservoir system. The main  input data  to  the model were  the  reservoirs physical
characteristics,  the  irrigation  water  diversion  estimated  by  CROPWAT  4
windows  software,  potential  evaporation  (mm),  daily  surface  inflow  (m3
/sec)  to
the  reservoirs  system.  The  outputs  of  the  model  were  the  release  (m3
/sec),
storage  (rrr'),  reservoir  level  (m),  and  inflow-outflow  relations  of  the  reservoir 4.63Mm3
remained  in  the  reservoirs  system. Therefore,  if the  releases of water
from  the  reservoir  systems  are  followed  according  to  the  monthly  irrigation
water  requirement,  this  can  sufficiently  serve  as  the  operating  rule  of  the
reservoirs.
The  study  also  provides  an  operation  rule  curve  using  the  application  of  HEC­

GIS BASED MODELING OF GROUNDWATER RECHARGE AND  HYDROCHEMICAL INVESTIGATION OF MAY-ADRASHA CATCHMENT,  NORTHERN ETHIOPIA
Creators: name: BY  ELIAS GEBREKIDAN GEBREMEDHIN
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: The May-Adrasha watershed  is  situated  in Northern part  of Ethiopia,  Tigray  regional  state with
area coverage of  135.50 krrr', Geographically,  it  is bounded between  13°59°-14°08° N latitude and
38°12°-38°2i' E longitudes. The area  is  characterized by  semi-arid climate with mono-modal  and
erratic nature  of rainfall.  The mean annual value of this rainfall  accounts  for  995 mm. However,
it's temporal and  spatial variation, not understood. Hence, the main objective of  the present work
was to  investigate the hydrological and hydro-chemical  situation. of the watershed to  improve the
groundwater resources management. A detail  and  intensive field investigation were  conducted  in
the watershed.  Field  survey  indicated that  study  area  is  covered by volcanic, Adigrate  sandstone
and  other  geological units. The  land-use/land-cover types  in watershed  include  cultivated, bush,
forest land and settlement area. Clay, sandy clay, and clay loams are the dominant soil typesBoth WetSpass  model  and  chloride  ion mass  balance  methods  were  applied  to  determine  the
mean  annual  recharge  of May-Adrasha watershed.  The  result  of WetSpass model  and  chloride
ion mass  balance method  indicated  6%  and  5.7%  of annual  precipitation  recharge.  In  addition,
the WetSpass model  simulation  indicated  that  80%  of the  precipitation  in  the  watershed  is  lost
through  evapotranspiration  while  the  rest  14%  becomes  surface  runoff.  The  hydro-chemical
investigation was  understood  by  analyzing  thirty  groundwater  samples  using  random  and  well
distributed selecting system for major and minor ionic concentrations and  insitu measurements of
EC,  temperature  and  PH.  The  groundwater  has  been  evaluated  using  the  interpretation  of  the
Aquachem  analysis  results. Accordingly,  the  dominant water types  in  the  catchment  are mainly
Ca-Mg-HC03-Cl  (36.67%),  Ca Mg-Ca-HC03-Cl  (30%), Mg-Ca-Cl-HC03  (16.67%)  and  Ca­
Mg-HC03  (16.67%) The  study  area  is  characterized  by  low  groundwater  recharge  due  to  the  presence  of  high
evapotranspiration  rate  and  surface  runoff  associated  with  high  temperature,  dry  wind  and .

description: Anthropic pressures deteriorate river water quality, so authorities need to identify their causes and define corrective actions. Physically based water quality models are a useful tool for addressing physicochemical pollutants, but they must be calibrated with an amount of data that is often unavailable. In this study, we explore the characterization of a model to design corrective interventions in a context of sparse data. A calibration indicator that is both simple and flexible is proposed. This approach is applied to the Middle Tagus Basin in central Spain, where the physicochemical concentration of pollutants is above legal standards. We quantify the effects of the main existing pressures (discharge from wastewater treatment plants, agricultural diffuse pollution and a major inter-basin water transfer) on the receiving waters. In particular, the study finds that wastewater treatment plant effluent concentrations should be reduced to up to 0.65 mg/L of ammonium and 0.55 mg/L of phosphate to achieve the environmental goals. We propose and prioritize a set of policy actions that would contribute to the good status of surface water bodies in the region.
