Landslide hazard mapping in the Nallu Khola watershed, central Nepal
Authors: Joshi Jagannath , Majtan Stefan , Morita Koichi , Omura Hiroshi 
Published: April 2021

This paper deals with landslide hazard mapping in the Nallu Khola watershed of Central Nepal. The study reveals that slope class 30o-40o is highly susceptible to sliding. The highest landslide density is seen on 35° slope with drainage frequency of 40-50 no./km2 Similarly, the lowest landslide density is found associated with the lowest average slope gradient and lowest drainage density.
Landslide hazard map shows that the high, medium, and low hazard areas occupy respectively 20%, 45%, and 35% of the watershed. Similarly, the landslide density is the highest in the cells that are categorised as high hazard. The highest number of landslide containing cells in high hazard rank suggests that the forecasted hazard ranks nearly match with the present field conditions. But there are some areas, where forecasted hazard ranks do not match with the present field conditions.
Prospects of groundwater quality for irrigation in central tracts of Lalitpur region, Uttar Pradesh, India
Authors: Haldar A. L. , Dev P. 
Published: April 2021

The quality of selected bored well and dug well waters from the central tracts of the Lalitpur region in the state of Uttar Pradesh, India, was investigated for irrigation purposes. The study area is situated within the latitudes 24° 35' N and 24° 43' N, and the longitudes 78° 20' 41" E and 78° 30' E in the basin of the Shahzad River, which is a tributary of the Betwa River. Granites and gneisses of Archaean age are exposed in various parts of the area.
The selected groundwater samples were analysed for major cations, anions, trace elements, pH, electrical conductivity (EC), sodium absorption ratio (SAR), residual sodium carbonate (RSC), permeability index (Pl), and sodium per cent (SP). The analysed data were plotted on Wilcox and U.S. salinity diagrams to evaluate chemical quality of groundwater for irrigation. The SAR values (ranging from 0.47 to 79) are within the permissible limits. A majority of samples (i.e., 57.5%) belong to C3-S, class whereas remaining samples (42.5%) fall in C2-S1 class. Plots of SP against EC indicate that a large number of samples (67.5%) fall within Excellent to Good type of water whereas remaining samples lie within Good to Permissible type. Hence the water can be used for all types of crop on soils of medium to high permeability.
Water pollution in Kucukcekmece Lake, Istanbul, Turkey
Authors: Pehlivan Rustem 
Published: April 2021

Water samples collected in February and August 1997 from the Kucukcekmece Lake were analysed by ICPMS-200 to determine the heavy metal concentration s (i.e., Hg, Cd, Pb, As, Cu, Cr, Co, Ni, Zn, Fe, Mn, Se, Ba, Al, and U). A comparison of these data with those of 1985, 1989, and 1995 revealed Hg and U contamination in the northern region, whereas Pb, Cu and Se contamination in the southern region of the Kucukcekmece Lake. Beside s, the influent waters were collected from the respective stream mouths, and were also analysed for heavy metal concentrations. The results showed the following contaminants: Hg, Se and U in the Ispartakule Stream, Hg, Cu and Se in the Sazli Stream, and Cu, Se and U in the Nakka Stream. On the other hand, a comparison of the results of February 1997 with those of August 1997 revealed that the amounts of As, Cu, Cr, Mn, Ba and Fe had decreased, but those of Pb, Ni, Zn and Se had increased in the lake since February 1997. Such kind of seasonal variation in concentration of heavy metals is attributed to pollution of the lake water by domestic waste, industrial effluents, and water-rock interactions.
Textural and compositional variation of sand along the Manahara-Bagmati river basin, Kathmandu Valley
Authors: Tamrakar Naresh Kazi , Gurmaita Hari Nandan 
Published: April 2021

The Manahara-Bagmati river basin is located in a humid climate and has a 51 km long low gradient profile. It collects sediments from metamorphic, metasedimentary, and fluvio-lacustrine sources. The sediment samples collected from 17 localities were studied texturally and compositionally to infer how sediment modifies due course of transport and whether the trends are interfered by mixing, recycling, and weathering. For this purpose, two size grades (i.e., 0-1ϕ and 2-3ϕ) were studied. Between them, the trends were more conspicuous in the 0-1ϕ sand grade. Mean (M2) and median (M6) grain sizes increase downstream exponentially. Sorting (σ1) also improves along the river course. Quartz content gradually increases downstream, whilst feldspars and rock fragments decrease remarkably along the river course. Rapid dilution of feldspars and rock fragments (from coarser size grade) occurs after 27 km of transport. The Modified Maturity Index, which ranges from 19.8 to 214, increases from the Manahara to Bagmati River sands. The mica content in the Bagmati River is from 2 to 8 times higher than in the Manahara River.
Within the studied river course, the mean projection sphericity (ψp) of quartz remains high (0.80 in average) but does not show any consistent trend. The mean roundness (ρ) of the 0-1ϕ sand grade increases conspicuously against the distance of transport. The majority of samples belong to submature class. Local influx of sediments and recycling are profound from Sankhu to Sanothimi and from Chobhar to Hasdol. Rapid weathering of labile grains is inferred in the middle reach of the Manahara- Bagmati river system (i.e., between Sanothimi and Chobhar).
Geomorphology of the Arun Valley, Eastern Nepal
Authors: Thakur P. K. , Adhikary P. C. 
Published: April 2021

The Arun Valley can be divided into the Upper Arun Periglacial Valley (UAPV) and Lower Arun Fluvial Valley (LAFV). The area separated by the linearly arranged ridges of Jaljale Danda, Harale Danda, and Sichok Danda. The UAPV lies in the north whereas the LAFV occupies the southern territories. The UAPV is further divided into four geomorphic provinces with fifteen distinct Holocene terrace levels, whereas the LAFV is divided into four geomorphic provinces with thirteen Pleistocene terrace levels.
The concept of geomorphic province is introduced to denote distinct geomorphological features formed in a type locality within a given geological time span. The identified geomorphic surfaces are morpho-stratigraphically defined at respective villages and have a wide geographic distribution.
This paper attempts to classify geomorphologically the whole Arun watershed and to compare the position of various terraces in terms of neo-tectonic activities. The main geomorphic features of the watershed and their relationship with the major geological structures are also discussed. The boundaries of the geomorphic province often coincide with the reported thrusts in the area.
Flood disasters in the Changjiang River and their geo-environmental implications
Authors: Liu Chuanzheng 
Published: April 2021

The archaeological records of past 5,000 years revealed that a period of high (13.6 m) flood occurred in the Changjiang River in 2,000 years BP. A serious flood disaster happened in the middle and lower reaches of the Changjiang River in 1998. This event reverberated through the whole country and led to the very important attention by many scientists and engineers.
In this paper, it is proposed to carry out the following three flood control measures. The first is to improve the flood control standard, which includes dredging river course and reinforcing dykes or dams. The second is to dig a channel through the Dongjing River (an old course of the Changjiang River) to divert the flood for avoiding the simultaneous flooding from different rivers and to remove the flood disaster for the Wuhan City. The third is to form gradually a great lake across the Changjiang River to contain the Dongting Lakeand Jianghan Lakes, which will supp ly the fresh water to be enough for the society and economic development of the middle China in the 21st century.
Pile foundation in karstic limestone terrain: a geotechnical constraint and its solution
Authors: Shrivastava Alok Kumar , Craig Derek John , Sharma Maunsell , Zakaria S. B. 
Published: April 2021

ABSTRACT
The karstic limestone terrain poses complex geotechnical problems, as there are many uncertainties in terms of position and dimension of cavities, sinkholes, pinnacles, and overhangs developed in it. The study deals with the 6.5 km long Ampang­ Kuala Lumpur Elevated Highway over the rivers Kelang and Ampang in Malaysia. The large-diameter bored piles and cast in-place piles were constructed for this purpose.
The toll plaza area is underlain by karstic limestone. In that area, the piles were located in rows extended as columns connected by crosshead whereas they were provided in pile groups of 2, 3, 4, or 5 connected by a rigid pile cap elsewhere. An instrumented test pile was load tested using static method and calibrated with site investigation results. To design the friction piles and end bearing piles, direct methods (viz. exploratory drilling and rock probes) and indirect methods (viz. resistivity survey and transient electromagnetic survey) were adopted. Based on lithologs, the piles were designed using the safety factor of 2 and 3. The rock probe results were used for designing the rock socket length of the end bearing piles.
There was much variation between the designed and encountered rock head levels as revealed during the time of excavation. In such cases, the geotechnical design of end bearing piles was reviewed. As in most of the cases, rock probe holes were inclined (as they slid over a rock cliff, overhang, or pinnacle) giving rise to wrong information of rock head levels. To solve this problem at site, a new integrated approach was evolved considering the 3D subsurface topography of rock head level of the area, position and dimension of karstic features, rock mass classifications, and bearing capacity calculation. Based on the above parameters and other measures (underpinning, micropiling, grouting etc.), the piles were designed and load tested.
A technique to discriminate landslides
Authors: Gunmg N. , Iwao Y. 
Published: April 2021

This paper describes an innovative way of distinguishing landslide-prone regions by simple and direct measurement and statistical interpretation of a topographic map. For this purpose, the topographic maps are enlarged and the contour interval and cross-slope distances are measured. A frequency distribution histogram based on chi-square method is constructed from the measurements. Generally, two fundamental patterns emerge from the histogram: the landslide-prone area shows several peaks whereas the remaining area shows just a single peak.
The technique was used to study the landslide-prone areas of the western Kyushu District of Japan. Six sub-regions were categorised depending upon the scale functions and probability parameters. The landslide-prone and safe areas were accurately discriminated under 0. 1 to 1% confidence level. The analysis independently discovered most of the hazardous areas that were later verified in the field.
Core drilling of the basin-fill sediments in the Kathmandu Valley for palaeoclimatic study: preliminary results
Authors: Sakai Harutaka , Fujii Rie , Kuwahara Yoshihiro , Upreti Bishal Nath , Shrestha Suresh Das 
Published: April 2021

Core drillings in ancient lake sediments of the Kathmandu Valley, central Nepal Himalaya were carried out in order to clarify the past Indian monsoon climate and its linkage to the uplift of the Himalaya. This is the first large-scale drilling project in the valley with full core recovery, and solely dedicated to academic research purpose. The drilling penetrated the whole sequence of 208 m thick Kalimati Clay, newly defined as the Kalimati Formation.
Based on the drill-core study, the sediments are divided into three formations: 1) Bagmati Formation, 2) Kalimati Formation, and 3) Patan Formation in ascending order. These formations have very distinct sedimentary characteristics: Bagmati essentially gravelly, Kalimati clayey and Patan sandy. The lower part of the Kalimati Formation, showing marginal lake facies, has been designated as the Basal Lignite Member. Judging from the lithology and sedimentary facies and previous studies on the Lukundol Formation, the Bagmati Formation is interpreted to have been deposited by the Proto-Bagmati River prior to the appearance of the lake before 2 Ma. The clay-predominant Kalimati Formation lying over the Lignite Member was deposited in an open lacustrine environment, which is mainly composed of carbonaceous clay yielding abundant fossil leaves and diatomaceous laminite. The fluvial sand of the Patan Formation rests on the Kalimati clay bed with a marked erosional base. The 14C age of the uppermost part of-the Kalimati Formation suggests that the lake water of the Kathmandu Basin was drained out later than 10 kyr B. P. (Fujii and Sakai 2002). Based on comparison of the present altitude of the ancient lake floor and top set beds of the lacustrine delta sediments (dated as 29 kyr B.P.), the water-depth of the Palaeo-Kathmandu Lake in the central part of the valley is estimated to be about 70 m.
Palynological study of the drilled sediments from the Kathmandu Basin and its palaeoclimatic and sedimentological significance
Authors: Fujii Rie , Sakai Harutaka 
Published: April 2021

Palynological study of a series of slimes obtained from a 284-m-long drill well in the Kathmandu Basin revealed palaeoclimatic records and deposition al environmental changes in the Kathmandu Valley during the last 2.5 myr. The slimes consist of fluvio-deltaic and lacustrine sediments comprising 218 m long muddy beds and 66.3 m of sandy beds. As a result of palynological study on the 189 pieces of slime, a total 43 types of fossil pollen and spores were identified. They comprise arboreal pollen of one family and 20 genera, non-arboreal pollen of 10 families and 10 genera and spores. In the pollen diagram, Quercus and Cyclobalanopsis are predominant, with frequencies exceeding 70%. Pinus, Alnus and Gramineae are the next dominant taxa. Three fossil pollen zones, which reflect major climatic change, were discriminated: Zone I indicates a cool climate from ca. 2.5 to 2.1 Ma; Zone II shows a warm and relatively dry climate without remarkable fluctuation from ca. 2.1 to 1.0 Ma; and Zone III is characterized by seven cycles of warm-and-wet and cold-and-dry climate from 1.0 Ma to present, which reflect the repetition of glacial and interglacial periods. The last cold maximum at 11 m depth seems to correspond to the last glacial age around 20 kyr B.P.
The sedimentation rate of the drill-well was estimated from an approximate age-depth plot based on approximate ages inferred by comparison between the palaeoclimatic curve drawn by pollen analysis and δ18O curve obtained from planktonic foraminifers of deep-sea sediments in the Indian Ocean. Consequently, the average sedimentation rate of the uppermost part from 115 m to 11 m in depth is estimated at 104 mm/kyr.
