The expediency of applying such an approach to assessing the seismotectonic potential in areas with weakened seismicity, which may currently be in the long-term seismic quiescence, is shown. This may be especially appropriate when assessing the seismic potential in the case of location of critical strategic structures and other environmentally hazardous facilities in such territories.","PeriodicalId":204277,"journal":{"name":"Geography and water resources","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116862854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The related social and economic strain in the region entails further decline in the living standard of the rural population and a decline in the level of agricultural production. The introduction of private land ownership and the emergence of new forms of husbandry in Kazakhstan resulted in a significant change in the spatial structure and functional development of agricultural land in the region under study. The use of land in Zhambyl region for agricultural development is based mainly on financial, economic and organizational mechanisms, while the problem of environmental effects of their transformation remains in abeyance, which resulted in the formation of an extensive, unprofitable agricultural production exposed to negative anthropogenic and environmental factors, resulting in the need to create agricultural land management strategy. The agricultural land management strategy of Zhambyl region of the Republic of Kazakhstan was developed on the basis of natural and agricultural, socio-economic, regulatory and nature protection indicators that reflect the priority activities to achieve sustainable use of agricultural land. At all stages of the development of the strategy, methodological developments and regulatory criteria adapted to the conditions of agricultural nature management were applied. The developed agricultural land management strategy is focused on the predominance of environmental priorities in land use, as a result of which agricultural land use will become cost-effective, environmentally friendly, and mutually beneficial.","PeriodicalId":204277,"journal":{"name":"Geography and water resources","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122533710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the issues of dynamic changes in the water level and the associated area and volume of water in the lake. The level of Lake Balkash is one of the main indicators of the state of the entire ecosystem of the basin. Prior to the regulation of the flow, the lake level cyclically changed, mainly between the marks 341 and 342 m BS, recently due to the period of high-water content of the incoming river flow, the lake level is between these marks. The uniqueness of the lake is that it is divided by a narrow strait into two parts with different water compositions – in the western part it is almost fresh, and in the eastern part it is brackish. Field studies were conducted in the Uzynaral Strait in the autumn of 2022, the article presents the results of this expedition.","PeriodicalId":204277,"journal":{"name":"Geography and water resources","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130374843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article examines modern methods of working with echo sounders, covering theoretical and practical aspects of using these devices. The article presents an overview of existing echo sounder classifications, methods for performing survey work in expeditionary conditions, and compiling final materials in the form of tables and vector layers. The main aspects of working with echo sounders are considered, such as equipment selection, parameter setting, conducting survey work, processing and analyzing data, and their integration with geographic information systems. Innovative developments and technologies that contribute to improving the quality and accuracy of results are described. Special attention is paid to the integration of echo sounders with other technologies, such as geographic information systems (GIS). The authors also consider practical aspects of using echo sounders in navigation, hydrography, and other areas.

The growth of summer air temperatures led to the decrease of mountain glaciations. In the last 45 years the glaciers in selected catchments of Gissar-Alay lost about 16% in area while the glaciers of the Pskem river catchment lost 27% in area. The river regimes, primarily the annual distribution of runoff react to the glacier decrease. The share of glacial runoff is over 25% in years with little precipitation, while it considerably decreases in years with abundant precipitation. One of the negative consequences of the glacier decrease is the formation of lakes in the periglacial area. The state of glacial lakes should be monitored, because they may pose outburst debris flow hazard.","PeriodicalId":204277,"journal":{"name":"Geography and water resources","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to this, the areas of protected territories, characterized by the intensity of surface washing and the regularity of the manifestation of these processes, have increased. The purpose of the study is to compile a map of the intensity of surface runoff, as well as the regularity of river watersheds in the Lankaran natural region. The conducted zoning of the territory of the Lankaran natural region according to the intensity of washing and its specific distribution characteristics has a special importance in agriculture. A variety of physical and geographical factors allowed us to draw up a map of the surface wash intensity in high altitude zones. An increase in surface runoff from the flat parts to the middle mountain belt has been revealed. The largest amount of surface runoff is observed in rivers with a flood regime in the lower border of the middle mountains, and with a mud regime – higher borders of the middle mountain belt. The intensity of surface runoff within the territory ranges from 0.011 to 0.14 mm/year. The analysis of the map of surface erosion shows that, starting from a height of more than 800 m, the amount of surface erosion gradually decreases from 0.09 mm/year due to the widespread distribution of difficult-to-erode rocks.","PeriodicalId":204277,"journal":{"name":"Geography and water resources","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121981199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
