The Sura River Basin Water Bodies’ Fractal Parameters

The Sura river basin water bodies (a river network with 800 watercourses and he Penza reservoir, the biggest on this territory with about 100 km2 water area) have been studied from the fractal geometry positions. The Sura River basin river network is characterized by Huck hydrological law. For the first time we present the methods of the river network fractal dimensionality determination with the use of Horton law and state the traditional approach with the use of the divider method. We have calculated fractal dimensionality of the Sura River basin river network by the both methods and have compared the results. As for the Penza Reservoir filled in 1979, we accurately hydrographically studied the banks, bottom and morphometric parameters as current in 2005. We give the method of box-counting, for the first time with its help we have calculated the reservoir bank lime fractal dimensionality. By the shape index, we have characterized the map layout of the Penza Reservoir and defined its place in the developed reservoirs’ classification according their map configuration complexity. This work material is meant as a supplement to the Scheme of the Sura River basin water bodies’ integrated use and protection.
