In an experimental investigation of the density current inflow into reservoir, the influence of
bed slope (0.000 to 0.003), type of suspended particles (salt and two sizes of sediment particles) and
advance distance (at three sations) on density and velocity profiles were investigated. Experiments
were carried out in a tilting flume. Observations and measurements showed that the velocity and
density profiles nondimensionalized with integral scales, in the same current but at different stations
were the same. Furthermore, there was a fairly good similarity between the velocity profiles
measured for types of currents flowing on different slopes. The dimensionless density profiles
measured in different current types were not similar. Turbidity currents with coarse sediment had an
almost linear density profile near the bed, whereas the saline density currents showed an almost
constant relative density near the bed.
