Influence of immersion depth of the sheet pile on the intensity of suffusion processes in pressure hydraulic structures

The research examines the influence of constructive features of a pressure hydraulic structure on the intensity of suffusion processes in the tailwater. The equations of non-vortex filtration fluid motion under a hydraulic structure in the form of a sheet pile wall are calculated by the finite eleme...
