Some of the methods for determination the velocity through constrict gap in cases of closing of in tidal regions and land out off the sea

Abstract

   The closure of the final gaps is one of the most difficult parts for the construction of the dams in tidal regions. The changes of velocities in the closure gap during the closure period can be computed. An attempt is made to introduce some formulae or the methods in which we can determinate the velocity of flow in the closure gap in order to apply in the construction of hydraulic works. These are also the results of a research part are done by working group of the Water Resources University.
