Special features of equilibrium coastline formation at small water storage basins

Abstract

A relation between equilibrium shoreline parameters and hydrodynamics on small storage basins has been inferred from field observations. Bearing and built-up promontories length is a function of wave acceleration distance (D) and of angle (α) of wave approach: y=kDsinα, where k is proportionality factor depending on order and deflection of the equilibrium shoreline festons. For outside shore festons (arcs) y=CR where y is length of bearing promontories, R - the arcs' radius, C - deflection value. Theoretical assumptions of B.A. Popov on the wave refraction and their impact on the shore have been confirmed by data on coasts formation at small water storage basins.
