Calculation of wave conditions in water area with sharp bottom unevenness

Abstract

Design of marine hydraulic structures is associated with definition of design wave conditions close by these structures. Safety and economy of hydraulic structures depend exactly on characteristics of wave conditions. In this paper, we consider two methods of obtaining the design wave: analytical calculation using Building Codes and Regulations of Russia and numerical modeling. The MIKE 21 software package was used in this case to perform the numerical simulation. A feature of the considered area is the unevenness of the bottom relief of the water area. The purpose of the article is to show clearly, how much characteristics of the design wave can be overstated when calculating in according to the normative document that does not take into account features of the water area.
