Understanding the hydraulics of flow over vegetation is very important to support the management of fluvial processes. The present research work experimentally investigates the flow over flexible vegetation. Experimental data collected in a straight flume having a bed covered by grass-like vegetation have been used to analyze different flow characteristics for flexible submerged elements. Experiments were conducted for both artificial as well as natural vegetation. An important parameter of sand bed channels, downward seepage, was considered in the present work on vegetated channel. Two different seepage percentages, 10% and 15%, were considered for exploring the change in flow characteristics with respect to no seepage case.enCIVIL ENGINEERINGThesis
