River basin is a unit of natural runoff process and it can be considered as an assembly of flux network of water and various materials including sediment and nutrients. Inside a river basin, various landscapes are distributed, and landscape is composed of physical background, bio-chemical actions and biological aspects in associated with the local ecosystem. When the fluxes pass through a landscape, they are changed in quantity and quality and bring about various ecosystem services. Due to population increase and economic efficiency with urbanization, artificial facilities and flux networks have been added to connect multiple basins. These artificial systems have consumed fossil fuels, emitted green house gas, and degraded ecosystem. Outflow fluxes from multiple rivers degrade our facing coastal area in particular bay area. Multiple river basins connected with artificial flux networks, including a facing bay area, is here called river basin complex, where eco-compatible management methodology is required.In the present study, we have developed an integrated numerical model for eco-compatible management of river basin complex around Ise bay in Japan, which includes following 2 sub-models: (1) Flux network model and (2) Ecosystem models of various landscapes. The model can describe the change of the material fluxes and ecosystem services under the various social scenarios on the Ise bay river basin complex.
