| Loopnet model was developed to simulate unsteady flow in the looped network channel, considering change of the time and space. In this study, the looped solution algorithm was derived and the accuracy and stability of the model was tested. The Gulpo river system was used to calculate the flood water levels considering the hydraulic structures, tidal effect and inflow hydrographs. The result of the simulation showed that the accuracy and stability of this model was reliable. The change of flood water level of the Gulpo River system and the spillway section were not greatly affected by the operation water level of the navigation channel. But this analysis showed that roughness was one of the very important physical factor in changing flood water level. |
