The analysis of a world database of formation of proran of low pressure soil dams which parameters contact the volume of a reservoir and a pressure is provided. The numerical method considering connection of reservoir volume with a pressure, the areas of a mirror with a pressure and taking into account additional factors of particle size distribution of soil and their mechanical-andphysical propertiesoffered.
.pro-wounds, soil dam, reservoir volume, pressure on a dam, particle size distribution, mechanical and physical properties of soil.
