【摘要】 分析改进的TOPKAPI模型的结构组成,并对模块计算做出相应调整.以地理信息系统技术为支撑,基于数字高程模型的数据构建数字流域平台,根据土壤、植被类型等资料建立属性数据库,结合空间水文气象资料,将改进的TOPKAPI模型应用于半湿润的洛河上游卢氏流域的洪水预报,并进行分析评价.应用实例表明,改进的TOPKAPI模型结构合理,在洪水预报应用中能取得较好的效果,具有一定的适用性.更多还原

【Abstract】 The structural composition of the improved TOPKAPI model was analyzed, and the corresponding adjustment was made to the module computation.Based on the support of GIS technology,the improved TOPKAPI model was applied to the forecast of the flood events in semi-humid Lushi River basin in the upper reaches Luohe River by establishing the digital basin platform based on DEM data and the attribute database of soil and vegetation types and by combining with spatial and hydrometeorological data.The relevant analyses and evaluations were performed. The application example indicates that the proposed model is reasonable in structure and leads to satisfactory results of flood forecast,and it is practical.更多还原
