Flood modelling evaluation in river meandering channel under tidal effect

Flood is one of the disasters in this country where around 29,000 km2 of 9% of the country are exposed to flood disaster. The purpose of this study is to develope a physical model under tidal influence for meandering in river channel and to assess the floodplain and water level for various flow cond...
