| Abstract |
Many computer models have been used for estimating the water quality and evaluating countermeasures. The models such as QUAL2E, STREAM, WASP, CE-QUAL have been applied in the waters so far. Some modeller assumed either that the flow of the waters is steady or that the storage change of the waters is negligible. And someone excluded hydraulic part from the quality simulation. It may cause inaccurate estimations of water flow and quality, particularly when the waters have seawards boundary and more inflow than outflow, etc. In order to show the velocity for water quality simulation of Paldang lake in dynamic condition, RMA-2 was performed with the monthly flow rate in 1997. The velocity was more sensitive to turbulence exchange coefficient than Manning`s n in Paldang lake. The results of simulation show that flows reverse around the Sonae island in late Summer because of less outflow than inflow and flows blocked by dam. |
