A runoff simulation system for a large river basin is applied to the Shiguang River Basin (6,000km2) in China. The watershed basin is subdevided into grid boxes with about 225km2 in which rainfall and evapotranspiration are assumed to be obtained by a numerical mesoscale atmospheric model. Runoff from each grid box is calculated and routed along channel networks. The system works well and it will be applied to the Huaihe River Basin (10,000km2) where HUBEX Project is going.
