Abstract

Field observations were carried out for the purpose of understanding the characteristics and the movement of suspended sediment which was carried by flood and then resuspended in the reservoir. From the analysis of water quality, the correlation of turbidity to SS and T-P was clearly defined, which can be useful for estimating the amount of SS and phosphorus flowing into the reservoir.<br>The current in the reservoir during the flood is numerically simulated using 3-D k-ε turbulence model, the result of which reproduces the turbidity profiles and the sedimentation distribution. These were in accordance with the measurement, and the model presented in this paper will give valuable information for the management of reservers.
