Specialized geoinformation system for automated monitoring of rivers and reservoirs
In recent decades, significant changes in the state and hydrological regime of water bodies have been observed under the influence of global and regional changes in the climate system and the impact of anthropogenic factors on the territory of the Russian Federation. It is known that the characteristics of reservoirs and watercourses, such as the area of water surface, the level and volume of water, the change in the area of sand deposits in river beds, and the processes of glaciation, are of fundamental importance for understanding and assessing the degree of impact of climate change and anthropogenic activity on water resources. This work provides description of a specialized geo informational system (GIS) for automated monitoring of the Siberian internal water bodies. It uses optical and radar remote Earth sensing data from Landsat-8, Sentinel-1, and Sentinel-2 spacecrafts. It also demonstrates GIS architecture, core modules and features. The technological features of the system, the sequence of processing and visualization of satellite data are presented. The proposed solution is a specialized content management system for website, which takes into account the specificity of GIS web applications. The paper presents the results for this system usage to track area dynamics of sand deposits in riverbeds, ice surface on water reservoirs and flood assessment. This system can be used to solve applied and fundamental tasks of hydrology of inland water resources.
