Method of forecasting coastal and submarine slope erosion at the lee side of hydrotechnical constructions

Abstract

Equation for the dimensionless curve is introduced describing the intensity of the coastal and submarine slope erosion. The length of the eroded coast and the intensity of erosion are deciphered by the curve in relative units, on individual points. Initial data are: the direction of the resultant of wave regime, the length of the construction and the point of maximum erosion during the first years of its operation. Corresponding coefficients are determined in some ports of the Baltic Sea. Calculations are given for the port of Ventspils, where was obtained a suitable convergence of calculation values and of the processes of coastal erosion during 60 years.
