Participatory service design and community involvement in designing future-ready sustainable learning landscapes
Authors: Sandström N , Nevgi A , Nenonen S 
Published: September 2019

Abstract
The United Nations Sustainable Development Goals (SDGs) work as a new agenda for sustainable development globally. Many if not most of the SDGs can be combined with different levels of education. This paper leans on previous work in Sustainable Education Design (SED), which looked at sustainability from its multifaceted angles with a broad global scope. The context of the study is a campus at a research-intensive Finnish university. The methodology entailed participatory service design approaches. For piloting, one classroom was chosen as a test bed. The data consist of workshops, use walks and structured interviews. The analysis started from identifying KPIs of sustainable learning environment creation, after which these were tested against Sustainable Education Design Criteria described in a manual book earlier. The key findings include nine preliminary alternative KPIs that were merged with previous SED criteria and related SDGs. The alternative KPIs were trialled in the test bed environment. These proposed alternative KPIs can be used as indicators for sustainability, innovation and learning during participatory change processes and in evaluating the outcome.

Authors: Spirinckx C , Thuring M , Damen L , Allacker K , Ramon D , Mirabella N , Röck M , Passer A 
Published: September 2019

Abstract
The aim of the PEF4Buildings project, commissioned by the European Commission, was to assess if the Product Environmental Footprint (PEF) method and related guidance documents developed in the framework of the Environmental Footprint pilot test phase are applicable at the building level. The project has been coordinated by VITO with TU Graz and KU Leuven as research partners. As a first step, two PEF studies on new office buildings were performed. The assessment of two office buildings allows to test the PEF method in different geographical contexts. In a second step, a possible approach to benchmark office buildings and to define classes of performance is developed. The approach is developed based on the findings of the PEF study on two new office buildings, the PEF guidance and dedicated desk research. It covers issues like how to define the reference building, how to define system boundaries, how many reference buildings should be defined and how to handle this range of different options. A third step of this study was devoted to the assessment at the building level and on how to link the assessment of the environmental performance of construction products to the assessment of a building by using the PEF method.

Abstract
The study was performed in Ha Tinh city of Vietnam and aims to investigate the current thermal condition inside houses of different urban neighborhoods by field measurement and survey. This is a starting point to develop sustainable housing and neighbourhood typologies as adaptation to climate change in the city. The survey was conducted in the summer of 2016. The analysis of the survey data showed that the satisfaction level of local inhabitants with actual thermal condition was relatively high, and the perception of those living in various neighborhoods did not differ significantly. To monitor the comfort level during summer in houses of Ha Tinh city, nine houses were selected based on their typologies and locations represented by local climate zones (LCZs). The investigation was conducted from late August to mid-October 2017. With data obtained from the field measurement, psychrometric analysis was performed and based on modified adaptive comfort model for South-East Asian people to evaluate thermal condition of considered houses. The analysis evaluated and showed explicit difference in comfort level between these housing typologies. Result of the analysis also showed a dependence of thermal comfort in different rooms of a house on their position and exposition to solar heat gained, but relation of comfort level to LCZs was not clear.

Authors: Stagrum A E , Kvande T , Engebø A , Andenæs E , Lohne J 
Published: September 2019

Abstract
The purpose of the study is to investigate data on climate implication and adaptation measures for energy use in buildings. It is based on a scoping literature review, concerned mainly with the main journals operating in the field of climate adaptation of the built environment. Research documents that significant changes are taking place due to the implications of climatic change. Studies concerning climate change impact on energy use in buildings in warm climates represent the majority of the findings. The volume of research within the consequences for the built environment in cold regions is found to be surprisingly low, especially concerning the pecuniary stakes involved. However, significant regional differences are observed. Though further research is of essence, policy/regulatory measures ought already to be taken, based on climate scenarios.

Authors: Romanovs A , Tihana J , Borodinecs A 
Published: September 2019

Abstract
The article describes the methods of improving the durability of new gas pipelines, as well as examines the need of rising the level of inspection security. Reliable gas pipelines is an important safety indicator of people’s housing areas and the industrial and commercial organizations work areas. The verification of durability and tightness of gas pipelines is one of the most important inspection, which shows the existence of defects in compliance of the gas pipelines and debt construction technologies and instructions. Detected on time defects influence the number of uncontrolled natural gas leaks in the pipelines. When assessing the impact of hidden defects on the durability and reliability of the gas pipeline, the gas pipeline monitoring process was made, and the defects in the construction of gas pipelines (polyethylene, steel) and fittings were more often detected, the effect of hidden defects of gas pipelines on the safety of pipelines was analyzed. The experiments described in the article were carried out to evaluate the durability and tightness of gas pipelines by simulating the hidden defects on new installed gas pipeline in two sites: Site 1 and Site 2, both places are situated in Latvia. The obtained data was processed and reflected in tables, charts, graphs, and the results were analyzed and summarized in the conclusions, and also proposals are made to improve the problem. In the article is described a calculation methodology, which proves what needs to be improved in order to increase the safety of newly built and reconstructed gas pipelines.
The Negative Impact of Solar Reflections Caused by Reflective Buildings’ Facades: Case Study of the Nasher Museum in Texas
Authors: Abdelwahab Sahar , Elhussainy Mariam , Labib Rania 
Published: September 2019

Abstract
Large reflective facades in buildings can cause severe visual discomfort due to the reflection of sunlight falling on buildings’ surfaces. These intense reflections can cause a intolerable glare and contribute to overheating the interior of surrounding buildings. An example of reflective building materials causing glare is experienced in Dallas, Texas, where a residential tower, which was fitted with a fully glazed façade, has caused intense specular reflections into the Nasher sculpture museum. The problem has caused glare and overheating of the interior spaces in the museum, thus leading to the damage and deterioration of the sculptures on display.
In order to examine the negative impact of the Museum Tower’s reflective façade on the visual comfort inside the Nasher museum, glare simulations are carried out at different times of the year. Additionally, to examine a possible solution to the glare problem, a proposed solution of using a less reflective material on the tower’s facade is examined via glare simulations. The initial set of simulations confirmed that tower skin contributed to blinding glare particularly at 12:00 and 15:00 on the summer and winter solstice, and the spring equinox. Use of less reflective material on the tower façade concluded that the tower façade still contributed to glare and that is due to its convex geometry.
Designing liveable urban open spaces in high density cities
Authors: Thilakaratne R 
Published: September 2019

Abstract
Hong Kong is one of the densest cities compared to other metropolitan cities with population density in some districts exceeding 57,250 persons per sqkm. Hong Kong’s liveability has been affected by factors such as escalating urban density, lack of open spaces, congested living environments, air pollution concentration and high proneness to pandemics.
Due to extremely high land premiums, some residents in Hong Kong live in nano flats small as 15sqm in high-rise towers. Given the congested nature of apartments, open spaces a play a vital role contributing to residents’ psychological and physical well-being. Due to peculiar topography and extreme high density, Hong Kong open space per capita is far from the WHO recommended standards of 9 sqm per person. Most urban open spaces are pocket spaces located among developments or adjacent to traffic roads with a high ratio of hardscape compared to vegetation. Due to challenging Summer conditions in Hong Kong with high temperature, humidity and stagnant wind most urban open spaces are underutilized.
This research investigates the factors effecting enjoyment of open spaces and design factors that could contribute to improve their liveability as public amenities. Exploration is based on liveability parameters such as user comfort, user behaviour, and spatial attributes of urban open spaces. Field data was collected on seven urban open spaces within Tsuen Wan district during dry Summer days. Field data analysis was supplemented by simulation methods, photographic survey of users’ movement within open spaces and user interviews.
All open spaces are located amidst of high-density urban environment facilitating easy access to residents in the neighbourhood proving sense of security. Findings indicate tendencies in using these open spaces in the afternoon after 4pm when these open spaces cool off from solar radiation. Majority of open spaces benefited from shading effect from surrounding buildings, however the seating arrangements have not benefited from the shading. Satisfactory wind speed could be observed in four open spaces out of the seven that benefited from South and SE wind directions providing desirable thermal comfort to users. The park that consisted of the highest ratio of greenery received the lowest wind speed due walled effect created by surrounding buildings. Ironically open spaces with high percentage of hardscape areas reported better wind performance indicating the possibility of high emissivity material creating low pressure pockets drawing winds in particularly in the afternoons.

The application of geometric models for the study of hydrological regime of protected shallows in reservoirs
Authors: Poddubnyi S A 
Published: September 2019

Abstract
This study considers the possibility of using geometric models in the study of individual elements of hydrological regime in different types of protected shallows in the Upper Volga reservoirs. Three types of models were chosen and verified. The formulas for calculating the bathygraphic curves of geometric figures approximating the beds of protected shallows are determined. Classes with different morphometric characteristics are identified using non-hierarchical cluster analysis for each type of shallows. Model calculations of areas and volumes of shallows are carried out depending on seasonal changes in water level, as well as estimates of thermal content, average monthly water balance and water exchange in the shallows.

Abstract
The values of maximal daily precipitation in the Amur River basin obtained using two different methods are considered. The first one is based on the hydro-meteorological approach to calculate the probable maximum precipitation. The second one is developed by the authors; it combines several statistical methods for calculating the values of the hydro-meteorological characteristics of low probability. Comparison of the results obtained by the two methods is made.
Scenario of expected climate and change of surface drain in north Kazakhstan
Authors: Cherednichenko A V , Cherednichenko Al V , Cherednichenko V S 
Published: September 2019

Abstract
Taking into account local peculiarities of the territory, scenarios of changes in temperature and precipitation for the future up to 2040 -2050 are built. On this basis, estimated probable change in runoff due to expected climate changes. The scenarios are based on physical laws, consisting in the presence of links between climatic fluctuations contained in time series of temperature and precipitation and climatic fluctuations in the indices of the general circulation of the atmosphere, identified on the basis of harmonic analysis. It is shown that one should expect stabilization of temperature in the region and even some decrease in it with a constant amount of precipitation. This will positively affect the surface runoff.

Glacier runoff and regime of rivers with glacial power (a case of study: Naryn river, Kyrgyzstan)
Authors: Akmatov R T , Alamanov S K , Choduraev T M , Pochechun V A 
Published: September 2019

Abstract
In this paper, we considered the glacial runoff of the Bolshoi and Kichi Naryn rivers, as well as their large tributaries which are main sources of the Toktogul water reservoir. Taking into account that rivers with glacier melting feeding form their water flow mostly during summer months, it would be interesting to analyse their water regime during warm seasons. All tributaries of the Naryn River demonstrate the runoff decrease from June to August; while the main channels of the Chon and Kichi Naryn themselves have another dynamic. In July, the seasonal snow cover already melted and the runoff formation occurs as a result of glacier melting that depend on monthly average temperatures. In August, the monthly amounts of precipitation and temperatures have decreasing trends that lead to immediate decline of the runoff volumes. Interestingly those fluctuations of precipitation and air temperatures and their impact on the glacier runoff forming have little impact on the total runoff volume of rivers. So, the glacial component in the run-off forming has exceptional value for the Naryn River during the summer period.
The effect of flow velocity distribution on matter transport in a curved channel segment with the effect of moving ships taken into account
Authors: Maslikova O Ya , Gritsuk I I , Debol’skaya E I 
Published: September 2019

Abstract
Ship transport produces a special type of bank waves, which have a specific effect on the boundaries of water bodies other than that of the wind-induced waves. In addition, the extent of frozen-bank erosion at a bend of river channel is determined by the entering flow velocity, which can increase in winter because of channel constriction due to freezing or ice jams and gorges. The accompanying vortices have a considerable effect on the flow velocity pattern.

Authors: Ipyana M , Mikova K D 
Published: September 2019

Abstract
Every year flooding of Songwe River has brought severe problems in the lower part of its catchment located in Kyela District. Floods lead to loss of people’s lives, destructions of infrastructures and properties. This study made floods analysis and short-term prediction of water stages. The study used rainfall data of Tenende weather station and water levels data at Kasumulu gauge station for identification of the flood patterns. Floods were grouped into three categories: floods with single peak, floods with several peaks and sprawled floods. The study recommends for the introduction and implementation of flood prediction practices, flood policy, and flood fight education, as well as continuous training of local residents on the best suitable traditional and modern ways of flood management practices and how to mitigate the floods effect.
Long-term dynamics of mercury pollution of the Bratsk reservoir bottom sediments, Baikal region, Russia
Authors: Pastukhov M V , Poletaeva V I , Tirskikh E N 
Published: September 2019

Abstract
This paper discusses the results of the monitoring of anthropogenic mercury contamination of the upper part of Bratsk reservoir. The paper shows that in the long-term, (1998-2018) there is an ongoing decrease of Hg concentration in the surface layer of bottom sediments. At the same time the study demonstrates that 20 years after the cessation of mercury electrolysis at the Usoliehimprom chemical plant, Hg concentration in the bottom sediments exceeds background levels by 5 to 54 times. Significant part of the Hg in the bottom sediments is stored in organic form, which is potentially dangerous since it may cause secondary contamination of aquatic environment and hydrobionts. The high amplitude of water-level fluctuations in the reservoir is one of the main factors influencing the distribution of mercury in the surface layer of bottom sediments and preventing the sealing of contaminated bottom sediments by terrigenous material.

Published: September 2019

Abstract
This research examines the characteristics of spatial distribution of As, Pb, Hg, Cd, Zn, Ni, Co, Cu, Cr in bottom sediments of Ust-Ilimsk reservoir. Two zones of the reservoir with elevated accumulation levels of potentially toxic elements have been determined: Vihorevsky bay (inflow from anthropogenic sources) and the reservoir area near the dam (inflow from natural and anthropogenic sources). Mobility of studied trace elements and the probability of the secondary contamination has been assessed based on the determined speciation of trace elements in bottom sediments.
Nutrient and organic matter dynamics in Lake Glubokoe
Authors: Tereshina M , Erina O , Vilimovich E , Sokolov D , Korovchinsky N 
Published: September 2019

Abstract
In this paper we present the results of field observations carried out at Lake Glubokoe (Moscow Region) in 2017–2019. Basic characteristics of the vertical distribution of main nutrient elements (phosphorus, nitrogen, and silicon) and organic matter (COD and chlorophyll-a) content are shown, along with their seasonal ranges. Due to the lack of surface runoff into the lake, the concentrations of total phosphorus and nitrogen are generally low throughout the year, with almost total depletion of inorganic phosphorus in the epilimnion during the growing season. Sufficient microbial activity allows most of the inorganic nitrogen to be presented in the nitrate form, except for late summer and fall, when plankton death rate exceeds bacterial nitrification capacity. During the period of hypolimnetic anoxia, significant amounts of mineral phosphorus and ammonia nitrogen are released from the bottom sediments. COD value shows a correlation with the intensity of both phyto- and zooplankton growth, which also affect the nutrient content.
Phosphorus accumulation in a lowland reservoir during the spring flood
Authors: Sokolov D I , Erina O , Tereshina M A , Puklakov V V 
Published: September 2019

AbstractOn the basis of detailed observations of 1984, 2012 and 2016 we estimated the accumulation of reactive phosphorus in the Mozhaysk reservoir during the spring flood. The results of this assessment depend on the completeness and origin of the used data: the absence of discharge gauging stations on the tributaries of the reservoir introduces an error of 30-40%, a decrease in the frequency of water quality monitoring from daily to 2 times a month or the use of empirical dependences in the absence of monitoring – up to 50-60% or more. During the flood, an overwhelming amount of reactive phosphorus accumulates in the reservoir due to a significant inflow (50-60% of the annual) and low outflow (from 1 to 13% of the annual). Over the past 30 years, there has been a significant reduction in the external phosphorus load on the reservoir.
