ALONGSHORE WAVES IN TRAPEZOID CANALS

SH. GAGOSHIDZE
(Georgia)

Alongshore waves are dominant in open river and maritime canals. For water area, from one side limited by arbitrarily sloped shore endlessly running deep into the sea, they were studied by Stocks, but due to significant mathematic difficulties for total depth canals the amount of accurate solutions is limited by just some private cases which are hardly applicable in practical use.

Some results of approximate solution of the problem about propagation of alongshore waves laying over the stationary flow in trapezoid canal are presented. The solution is based on the application of direct Galorkin-Kantorovich method in three-dimension linear equations for wave hydromechanics written in cylindrical coordinate system. The obtained solutions maintain the three-dimension structure of the waves over the shore slope and lead to the results easily applied in the design.
