Abstract

The object of this paper is the problem of the appreciation the efficiency of flood-control measures and their influence on the channel processes at the early studies of design. A new method of the numerical modeling of effect of river training on the channel processes of mountain rivers is proposed. The example of the efficiency of this method may be the flanking dike, witch was designed on the bases of the numerical modeling dates, built on the mountain river Mzumta (Sochi, Russia). With the help of the numerical modeling of this types, most efficient type was chosen – it is the building of the flanking dike on the island, situated in the inside delta of the river and the channel dredging of the left fork. In the year 2004 all the project measures suggested had been successfully realized. The flanking dike had already seen a few large floods and now it is successfully working.
