Investigation of hydroelectric energy potential of the Zab River Basin using geographic information systems and remote sensing methods

The article describes experience of using geographic information systems in archaeological research of the Brovarka river basin. This river is а part of surface waters of Pereiaslav region and it is located in the south-eastern part of the region. The study of sites in the region began in the middle of the XIX century. From this time until the end of the 1960s the research focus was concentrated only on the certain objects of the micro-region. During the next period (up to the early 1990s) the several field studies was conducted on the territory, that allows to accumulate many archaeological materials. Despite the aforementioned, yet the purposeful study of the territory was not carried out. In the early 2000s a generalization of information about archaeological sites in the micro-region and their further field survey was started. So, we have begun a comprehensive study of archaeological sites, lined up within the Brovarka river basin. The need to operate a large amount of diverse information and to attract a wide range of sources has forced us to use new approaches in the study of the past of the region: the use of geographic information systems, remote sensing data and GPS positioning. The main research focus was concentrated on the study of the ancient settlement systems. The study was carried out in the context of the implementation of following three areas: а records of archaeological sites, an analysis of the spatial characteristics of ancient settlement systems and use of remote sensing data for different research needs. The particular features and results of their implementation are proposed in this publication.

Accurate information on the state of water resources in the Lake Victoria watershed is crucial for planning and sustainable development in the East African region. This region largely depends on its natural resource-base for economic development, and therefore comprehensive information on its resources dynamics is key in implementing poverty alleviation strategies, improving human condition and preserving the biological systems upon which the region‘s population depends. This chapter focuses on key issues, which have emerged as a result of population growth and development in the region. The research on which this chapter is based aims to address the concerns on land use and settlement trends in the study sites, vulnerability of the communities to water stress and sustainability of the livelihood systems in the watersheds of Nzoia River Basin (Kenya), Nakivubo Wetland (Uganda) and Simiyu River Basin (Tanzania). These communities engage in unique land use practices that have intensified environmental degradation in recent times. The research adopts a multi-disciplinary approach in bringing to the fore the various processes affecting watershed resources use and management in the selected wetlands of the Lake Victoria Drainage Basin (LVDB). The data presented covers trends in vegetation cover loss, pesticide pollution and general water quality parameters. Geographic information systems (GIS) and remote sensing techniques were employed to unveil land use patterns that have resulted in the degradation of the watershed. Wetland degradation levels have been characterized using secondary data generated by analytical techniques. New emerging challenges of environmental degradation caused by industrial, domestic and agricultural activities are presented and discussed. The potential of the new science of hydroinformatics in integrated watershed management through mathematical modeling, geographic information systems analysis and water supply management is highlighted.

Purpose: determination and analysis of the relevance of the geographic information systems (GIS) use in assessing the degradation degree of agricultural land as a result of erosion processes. Discussion: the article is devoted to the problem of studying modern methods for assessing the state of agricultural lands subject to negative processes. Water and wind erosion (deflation) are the most widespread and harmful types of soil degradation. So, water erosion (19.32 % of the territory of the surveyed lands) is the most widespread on the agricultural lands of the Russian Federation. The main tool for identifying soil degradation processes is the monitoring system, and the most effective and promising method for assessing the degree of land degradation is the Earth remote sensing (ERS) method. All of the above, together with reclamation techniques (land reclamation, field-protective afforestation, etc.) is a means of preserving and improving the quality of agricultural land resources, including those prone to erosion and deflation. The main advantages and examples of detecting soil degradation using remote sensing data are presented. The analysis of information on the spread of negative processes on the lands of the Russian Federation is carried out. Based on the analysis of the current state of land erosion, it becomes urgently necessary to carry out a set of measures to stabilize and restore the fertility of agricultural land. Conclusions: objective and reliable data on the state of soil erosion can be obtained only by combining ground (agrochemical surveys) and remote sensing methods of the Earth. Since the assessment of the degree and territorial distribution of soil degradation types can be carried out with high reliability using aerospace photography materials and ground-based research data, it is necessary to use remote sensing methods of the Earth and geographic information systems more widely, in addition to field surveys.

Geographic Information Systems (GIS) are shown to provide a number of capabilities which are of particular use to river basin operation and planning. GIS systems have the ability to display and graphically summarize both the input data for the analytical models and the results of application of management models using that data. The graphical display of input data can assist interpretation of conditions within the basin through depiction of spatial and temporal patterns in that data. GIS can also reduce the time required to enter data and improve the reliability of that data by reducing the errors in the data. The ability to display the results graphically improves the man-machine interaction which is generally accepted as being an integral part of multi-objective water resources analysis. Another important role for GIS is its use as an efficient interface between the data base and the operational computer models. It is asserted, however, that GIS should not be considered a means of providing final answers to complex water resources planning issues. It should be seen, rather, as an important component of Decision Support Systems by which information on the basin issues is transferred to the decision maker for his consideration. Specific aspects of the application of GIS are discussed in relation to a hypothetical river basin system used primarily for hydroelectric energy generation.
