Abstract. An integrated model is being developed to advance our understanding of the interactions between human activities, terrestrial system and water cycle, and to evaluate how system interactions will be affected by a changing climate at the regional scale. As a first step towards that goal, a global integrated assessment model including a water-demand model is coupled offline with a land surface hydrology – routing – water resources management model. In this study, a spatial and temporal disaggregation approach is developed to project the annual regional water demand simulations into a daily time step and subbasin representation. The model demonstrated reasonable ability to represent the historical flow regulation and water supply over the Midwest (Missouri, Upper Mississippi, and Ohio). Implications for future flow regulation, water supply, and supply deficit are investigated using a climate change projection with the B1 emission scenario, which affects both natural flow and water demand. Over the Midwest, changes in flow regulation are mostly driven by the change in natural flow due to the limited storage capacity over the Ohio and Upper Mississippi River basins. The changes in flow and demand have a combined effect on the Missouri summer regulated flow. The supply deficit seems to be driven by the change in flow over the region. Spatial analysis demonstrates the relationship between the supply deficit and the change in demand over urban areas not along a main river or with limited storage, and over areas upstream of groundwater dependent fields, which therefore have an overestimated surface water demand.

The advantages of the basin approach in the study of regional water use are justified in the article, water management areas according to the water management division of the Russian Federation were used as territorial units of the study. A universal methodic for the integrated assessment of the region’s water management activities was developed, based on geo/information technology. Stages of the study are described, including water management of the area, ranking based on the total anthropogenic load on water bodies and river basins, zoning of the territory to optimize the target use of water resources. The GIS of water use of the Lake Baikal basin is developed on the basis of governmental statistics, mass media examples of organization of water management data, as well as the results of automated mapping of water bodies. The results of water management regionalization are presented and spatial regularities of water use organization in the investigated territory are revealed. The ranking of river basins and water bodies according to the degree of anthropogenic load has been carried out, ecological problems of the region have been identified and their spatial localization has been fixed, the exact locations of pollution sources and their influence on water management have been established. Zoning of the territory under study for targeted use of water resources was proposed, five unique zones were identified, differentiated according to the special conditions for the formation of water resources and the specific use of water bodies, as well as the nature and intensity of the current and forecasted water use. A set of measures to optimize water use within the zones of targeted use of water resources is proposed.

The based on the data of laboratory studies, an integrated assessment of the quality of water resources the village of Mala Belozerka. Analytical researches have search character of an integrated estimation of level of pollution of district and are executed by a method which is offered by researchers Kryzhanovsky E.M. and Davydov I.V., is of a recommended nature and based on the algorithm of the officially approved methodology of the KND 211.1.1.106 "Organization and implementation of observations of surface water pollution (in the system of the Ministry of Energy)". According to the results of the calculation of the total pollution rate, it was found that the local water resources are characterized as dirty, despite the relatively high quality of groundwater, which is used as a source for drinking water supply to the rural population.
