1-D AND 2-D SIMULATION OF THE FLOW AROUND DISCONTINUOUS DYKE
There are many kinds of traditional flood management in Japan. Some traditional flood managements still work as a disaster reduction system. A discontinuous dyke discussed here is one of them. The discontinuous dyke has some functions by which the river water inundated through it to the surrounding flood plains during floods. However, its hydraulic function has not yet fully clarified. In this paper, the flow around discontinuous dyke was calculated by one-dimensional model and two-dimensional model. In one-dimensional simulation, it is necessary to determine an overflow discharge equation with experiment data. From the result of previous work, the overflow discharge equation has been investigated experimentally. A good agreement between the calculated and measured data can be seen. Then, the flood flow in Kameoka Basin, Kyoto, Japan is calculated by two-dimensional model without any experimental equations of overflow discharge, and the inundation process of this area is simulated. Inundation process in this area can be simulated.
