Forecast Model of Reservoir Inflow Based on DEM and the System Development
The Digital Elevation Drainage Network Model (DEDNM) was established based on the Digital Elevation Model (DEM) with spatial watershed heterogeneity considered. The watershed was divided into a series of discrete sub-cells as the runoff generation and conflu-ence calculation unit, and the area weighting of each sub-cell was calculated. The digital hydrological model (DHM) was constituted by coupling the DEDNM with Xinanjiang mod-el, a lumped hydrological model. The integrated flood forecast system is based on a client/serve (C/S) mode. The flood forecasting system was applied in two reservoirs, Meishan Reservoir and Nianyushan Reservoir which belong to the Shiguan River watershed-the in-tensified observation field of GEWEX Asian Monsoon Experiment (GAME) project. The re-sults showed that the established forecasting system not only performs well in simulating flood process of reservoir inflow, but also satisfies the precision requirement of real-time flood forecast. This provides approaches to make full use of available spatial technologies and data for rainfall-runoff modeling and technique improvement of hydrological forecast.
