Abstract

The significant data array has been obtained within the framework of the works carried out at the Institute of Limnology RAS for assessing the water resources of the lakes of the Russian Federation. This array makes it possible to develop a detailed map of lake percentage of the Russian Federation. An analysis of the change in the lake percentage coefficient is the most convenient for estimating the spatial heterogeneity of the distribution of lake water resources. For regions located within the water deficit zone, the values of the lake percentage in different seasons and in different years may differ from the mean values obtained earlier by the authors. Analysis of changes in lake coverage in such regions is possible using satellite imagery data for different seasons of the year and for different periods of water content. A study of the dynamics of the lake water resources of the insufficient moisture regions was started using images of Landsat 5 TM Level-1. The analysis of scenes for different periods of water content in 2010 showed a 20 % reduction of the total surface water area within the five test sites located in the south of the Tyumen region for the period from May to August. The quantity of reservoirs are larger than 10 hectares has decreased with 60 to 46. Map-schemes of lake percentage for the periods of different water content for the trial territory were constructed on the basis calculation values of lake percentage. The obtained characteristics of the temporal dynamics of the surface water area, as well as the analysis of the maps of lake percentage, allow us to refine the results of the assessment of the water resources of the lakes of the Russian Federation for the regions of water deficiency.
