SIMULATION OF RUNOFF DISCHARGE AND MATERIALS FOR ISE-BAY RIVER BASINS

Abstract

A river basin is an assembly of flux net work. It is recognized that ecosystem in a river basin plays a role to change the fluxes and to bring ecosystem service.

We developed hydrological and material cycle simulation model. This simulation model is composed of two parts: slope and river channel. The model contains to artificial flux changes such as dam, life drainage and sewage disposal plant. This model has been applied to the Ise-bay river basins. As a result, we found that the simulation results agree with field mesurements.
