The optimum interpolation method is used to estimate radar measured rainfall which then be applied to topmodel to simulate discharge of shiguanhe catchment during the summer of 1998 in game hubex project . comparison of simulated discharges between radar and rain gauge implements over a 1500 - hour series 运用雷达联合少量雨量计方法估测流域面雨量，结合game hubex国际合作项目1998年加强观测期在史灌河流域获取的水文观测资料和topmodel进行降水径流模拟，并与稠密雨量计站网测量的面雨量进行流域出口流量模拟的对比试验。
