Assessment of geoecological conditions and the depletion risk of the river Belaya catchment area

At the present time water resources in the Republic of Bashkortostan (Russia) are exposed by negative anthropogenic influence. Natural processes also contribute to the depletion of water resources. The implementation of the water management system raises a number of methodological problems: the uncertainty of the criteria for assessing the ecological status of water bodies; the complexity of the relationship between the quantitative and qualitative characteristics of the water body due to the regional natural, anthropogenic, climatic features of the territory. The aim of this study is to development of a method for calculating the risk of water resources depletion. The method was tested on the river Belaya (Republic of Bashkortostan, Russia) catchment area. In calculating of water resources depletion risk several parameters were taken into account in particular: the area of watershed, catchment data of surface water and groundwater, data of land use, the average annual runoff, karst phenomena, vegetation. In this paper we use the method of import of geo data containing the soil composition, vegetation, geological structure and forest to assess the ecological condition of the river Belaya. There are defined the catchment areas of the river Belaya, which required immediate management solutions. Mapping of the Belaya River catchment areas requiring immediate management decisions was carried out
