Different flow pafterns of density currents in reservoirs are discussed. In delta region, lateral density currents from non-stratified flow in the main channel occurs resulting in floodplain deposits with silt and clay. Density current deposition downstream of the topset bed forms wedge-shaped deposit along the reservoir. When a density current reaching the dam under backwater effect, muddy lake deposit may occur before the dam with adverse impacts.
