Today, demand for water is on the rise everywhere in the world, particularly in arid and semiarid countries including Iran. About 70 % area of Iran suffer somehow from the lack of precipitation. The research is dedicated to estimation of main probabilistic characteristics of river flow regulation by perspective water reservoirs with help of annual runoff process simulation by Monte-Carlo method. Results of the research allows do conclusion about possibility of application Monte-Carlo method for simulation of annual runoff and about necessary of runoff regulation by water reservoirs on the rivers of Iran – Gharasu and Hablirud. Their annual runoff regime is differing significantly. From the estimated 1000-year hydrological series were formed sequences of 2-years, 3-years, 4-years and 5-years periods. Preliminary analysis of the runoff difference integral curve and planned water loss showed that under the current situation, several consecutive deficit years are likely to exist in a row.

The world around us is very diverse physically, biologically, culturally, and so on. These diversities have provided us with many advantages so that by employing them, we can get short-term, long-term and sustainable benefits. Given the importance of the sustainable use of resources, it seems that the first step towards this purpose is identification and scientific study of these resources. Since 1990s, geologists and geomorphologists began to use the term geodiversity, which led to opening of a new direction in studies related to this subject. Given the importance of identifying potentials of geodiversity and the need for its conservation and sustainable use, this research aimed at analysis of geodiversity and its conservation and sustainable use. To this purpose, the study area based on its natural properties was divided into 3 classes. Then, for each of these classes, determinants features of geodiversity, including geology, hydrology, soil, etc., were investigated and the geodiversity index was calculated. The results showed that Class 1, located at the north of the basin, had the highest geodiversity index (6.59), mainly because of existence of calcareous formations and various geomorphologic forms, and the smallest index value (2.9) was calculated for the Class 3, which is mainly formed of alluvial deposits

Bathymetric and Bottom Temperatures GIS of the Barents and Kara Seas

The Arctic shelf is the most important link in the climatic kitchen of our planet: here, under the influence of the flow of the great Siberian rivers, a layer of freshened water is formed, blocking access to the surface of relatively warm saline waters of the North Atlantic origin, which prevents the melting of the ice cover of the Arctic basin Thus, the processes occurring in the relatively small size of the Arctic region, are able to change the state of the planetary scale system. Such active attention to this problem is associated with the development of offshore oil and gas fields. Permafrost established under the bottom of the Arctic seas occurs at a distance of up to 120 km from the coast, at a depth of several tens of meters. The temperature of the sea day is an important characteristic in assessing the state and direction of the evolution of sub-permafrost. To solve the part of this problem we tried to make bathymetric and temperature GIS of costal and offshore permafrost in Barents and Kara Seas. The GIS is based on the sea depth, temperature, and salinity of sea water collected by the marine organizations of Russia, the USA, England, Germany, Norway and Poland for the Barents and Kara Sea regions from 1898 to 1998. From all sources in the areas of the Barents and Kara Seas, more than 1,000,000 oceanographic stations were selected for processing. These maps are only the part of the GIS project.

Land use change modeling using integration of GIS-based cellular automata and weights-of-evidence techniques
Saleh
Abdullahi
In recent decades, attaining urban sustainability is the primary goal for urban planners and decision makers. Among various aspects of urban sustainability, environmental protection such as agricultural and forest conservations is very important in tropical countries like Malaysia. In this regard, prediction of future land use changes is very useful for Malaysian government. This paper attempts to propose an integrated modeling approach to predict the future land use changes using integration of GIS-based cellular automata and weights-of-evidence techniques. The cellular automata (CA) were applied for calculating land use conversion. In addition, weights-of-evidence (WoE) which is based on Bayes theory using several urban-related parameters was utilized to calibrate CA model and to support the transitional rule assessment. The results showed that the modeling approach supports the essential logic of probabilistic methods and indicates that spatial autocorrelation of various land use types and accessibility is the main drivers of urban land use changes.

City compactness assessment based on Multi-criteria decision making and Bayes theorem
Saleh
Abdullahi
In recent decades, compact urban development and smart cities are recognized as most sustainable urban form in an effort to protect natural environment and decrease air and water pollution. Therefore, evaluation of existing compactness and sustainability of an area is an essential task before the real development takes place. There are few studies regarding city compactness assessment and most of them have considered only a few aspects of compact development analysis. This paper, analyzed urban sustainability of Kajang city (Malaysia) through a comprehensive city compactness assessment using Geographical Information System and latest remote sensing technology. Mixed land use development, urban density and intensity were the main indicators of the analysis. Finally multicriteria decision-making and Bayes theorem was applied for overall compactness assessment. The results classified the zones of the Kajang city in the range of least to most compact zones with the compactness. These promising results can help local government to improve the compactness of least compact zones to make Kajang city more sustainable. Furthermore, the results revealed that efficient public transportation and proper community facilities are the key factors to achieve sustainable urban development.

Drinking water with high quality is one of our most vital resources, and when our water is polluted it is not only devastating to the environment, but also to human health. So the aim of the research is investigation groundwater quality using Schoeller diagram method in north of Fars province, southeast Iran. For determination of groundwater quality, parameters of chlorine (Cl), sodium (Na), sulfate (So4), total dissolved solids (TDS) and total hardness (TH) were used. Using Inverse Distance Weighting (IDW) interpolation maps of each parameters using inverse distance weighting (IDW) method and then fuzzy and AHP method were determined. The results of fuzzy method showed that, except the parts of south, all of the area was not suitable for So4, Cl, and Na that had the value close to 0. Also except the some parts of north was suitable for TDS and TH that had the value close to 1.

Evaluation of safety of hydraulic structures as part of the ecological monitoring of streams (for example, the Osetr river in the Moscow region) environmental aspects
Yurova Yulia
Dmitrievna
The article summarizes the results of a comprehensive environmental assessment of the Osetr river basin in 2018 based on the results of engineering and environmental surveys obtained in the framework of environmental monitoring. The current state of the dam on the Osetr river in Zaraisky district is assessed, the forecast of possible changes in the environment under the influence of anthropogenic load is presented in order to prevent, minimize or eliminate harmful and undesirable environmental and related social, economic and other consequences and preserve optimal living conditions of the population. The analysis of the current state of the problem has shown that the safety of small waterworks is reduced due to the receipt of unreliable initial data for the assessment of the environmental situation at the site, which leads to serious violations of the rules of operation, damage to dams and reservoirs and as a result has a significant impact on the environment with subsequent positive or negative effects.
