The present study applied a numerical model to investigate various configurations of the perched beach including submergence ratio of the breakwater, groin with/without gap, the gap width/location and emerged/submerged groin. These configurations have been compared from the point of view of wave heights, currents velocities, flushing and shoreline changes to develop general guidelines for the design of similar constructions. An actual scale model of a perched beach designed and constructed to provide a safe swimming conditions. The project area is constructed along the North-West coast of...

To analyze and evaluate the effect of releasing flow discharges on river meandering and the scour at the bridge piers. This part of river meandering includes 13 piers distributed on 3 bridges. The meandering reach is located on Rosetta branch in Egypt. It is consisting of two successive bends of length of 9.0 Km from Km 145.00 to Km 154.00 D.S of El-Roda Gauge at Kafr El-Zayat City. This reach is selected to conduct the current investigation. Several sorts of data were collected including site maps, velocity measurements, bed samples, hydrographic survey data, water levels and discharges at...
