【摘要】：采用模塊化開發(fā)方法構(gòu)建基于分布式水文模型DWSM的流域水沙模擬計算系統(tǒng),用以研究寧夏和內(nèi)蒙黃河段(下河沿至頭道拐)流域的產(chǎn)流產(chǎn)沙情況及水沙輸移規(guī)律。該系統(tǒng)主要針對黃河上游寧蒙河段及其相關(guān)流域,借助DWSM模型在流域計算模擬方面的優(yōu)點,系統(tǒng)集成數(shù)據(jù)庫模塊、河網(wǎng)提取模塊、DWSM伺服模塊、DWSM模型模塊以及水文成果對比與顯示模塊等主要功能模塊并調(diào)節(jié)計算參數(shù)。在介紹系統(tǒng)框架結(jié)構(gòu)、模型原理和計算流程的基礎(chǔ)上,采用寧蒙河段的實測資料對其進(jìn)行應(yīng)用驗證。計算分析結(jié)果表明,所構(gòu)建的寧蒙黃河流域水沙模擬計算系統(tǒng)在該區(qū)域具有較好的適用性。
[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.
