Abstract
Riparian vegetation plays a crucial role in determining the flow behavior in the channel. The effect of flow on the slope and main channel varies based on the size, type, and density of floodplain vegetation in a compound channel. Though vegetation distribution in different water bodies is non-uniform, most studies mainly concentrate on uniformly distributed vegetation with fixed vegetation height. Laboratory studies were conducted to address this issue as it was not explored properly. Experiments were performed by taking partially vegetated rectangular channels and compound channels. Rectangular channels were considered to compare flow between homogeneous height/single-layered partially vegetated channels and heterogeneous height/multi-layered partially vegetated channels. Compound channels of three bank angles, namely 310, 450and 900 were considered with vegetated floodplains.
