Abstract
A one-line analytical model of groin impact on a sandy beach suggested before by the authors is further developed in this work. The new version of the model considers trapping capability of groins to be dependent on shoreline displacement associated with infilling of inter-groin compartments. Thus, a feedback is implied between accumulation rate and evolution of shoreline contour which tends to its equilibrium state. It is shown that accumulation in a groin field is governed by rather fine mechanism operating in a relatively narrow range of conditions. The groin system is most efficient when the step of the groin field coincides with the length of an influence zone of a single structure. This in its turn leads to an optimal relation between the length of the structures and the distance between them. The model calculations demonstrate the ability to control the groin system operation by changing its parameters.
