建立了小型水库及淤地坝泥沙淤积体的概化模型。结合水库及淤地坝泥沙观测数据,采用以小型水库的特性征曲线为基础的泥沙淤积量测算方法,对好水川流域小型水库及淤地坝淤积量进行了估算。运用泥沙淤积体规则概化的测算方法对估算结果进行验证,并推求区域侵蚀模数。该方法计算简单,结论可靠,可为进一步研究该流域的水沙规律提供理论依据,并为宁夏南部山区的淤地坝淤积量估算提出一种简便的算法。
A generalized model of sediment deposition in small reservoirs and silt reservoirs has been established. Combined with the sediment observation data of reservoirs and silt reservoirs, the calculation method of sedimentation amount based on the characteristic curves of small reservoirs was used to estimate the sedimentation amount of small reservoirs and silt dam in the Haoshuichuan Basin. The results of the estimation are verified by using the rules and generalized calculation methods of sediment deposition and the regional erosion modulus is deduced. The method is simple in calculation and reliable in conclusion, which provides a theoretical basis for further study on the law of water and sediment in the watershed and provides a simple and convenient algorithm for the siltation of siltation dams in the mountainous areas of southern Ningxia.
