Елизарьев А.Н., Фащевская Т.Б., Афанасьев И.А., Кияшко И.Ю.
The indicators of sustainable development in the field of rational water use, developed by international organizations (UNO, the World Bank) were analyzed. The analysis of domestic and worldwide methodical approaches to calculation of rivers’ environmental flow as the criteria of rationing the irrevocable water resources intake was carried out. The map of environmental flow amount distribution over Bashkortostan Republic territory, via GIS-technologies was created. As a complex indicator of irrevocable water resources intake the territory water potential concept and the method of its calculation were offered. Water potential of Bashkortostan Republic territory was estimated via GIS-technologies. It was identified, that central part of Bashkortostan Republic, with a lot of industrial centers, located by the shore of Belaya River, is the most provided with water resources. It was shown, that the use of Spatial Analyst mathematical tool gives an inappropriative results in case of low developed system of hydrological monitoring.
