【摘要】：采用模块化开发方法构建基于分布式水文模型DWSM的流域水沙模拟计算系统,用以研究宁夏和内蒙黄河段(下河沿至头道拐)流域的产流产沙情况及水沙输移规律。该系统主要针对黄河上游宁蒙河段及其相关流域,借助DWSM模型在流域计算模拟方面的优点,系统集成数据库模块、河网提取模块、DWSM伺服模块、DWSM模型模块以及水文成果对比与显示模块等主要功能模块并调节计算参数。在介绍系统框架结构、模型原理和计算流程的基础上,采用宁蒙河段的实测资料对其进行应用验证。计算分析结果表明,所构建的宁蒙黄河流域水沙模拟计算系统在该区域具有较好的适用性。
[Abstract]:A water and sediment simulation system based on distributed hydrological model (DWSM) was established to study the runoff and sediment yield and sediment transport in the Yellow River region of Ningxia and Inner Mongolia (from Xianhe to Tou Dao Guai). This system mainly aims at the upper reaches of the Yellow River and its related watersheds. With the help of the advantages of the DWSM model in the basin calculation and simulation, the system integrates the database module. The main function modules such as DWSM servo module, DWSM model module and hydrological data comparison and display module are used to adjust the calculation parameters. Based on the introduction of the system frame structure, the model principle and the calculation flow, the practical data of the Ningmeng River reach are used to verify its application. The results of calculation and analysis show that the simulation and calculation system of water and sediment in the Ningmeng Yellow River basin has good applicability in this area.
