Abstract

A mathematical model is used for the estimation of the annual sediment yield resulting from rainfall and runoff at the outlet of Nestos River basin (Toxotes, Thrace, Greece), where the ecologically interesting Nestos delta exists. The model is applied to that part of Nestos River basin (838 km2) which lies downstream of three dams. Two dams (Thissavros and Platanovryssi) have been already constructed, while the third one (Temenos) is under construction. The model consists of three sub-models: a rainfall-runoff sub-model, a surface erosion sub-model and a sediment transport sub-model for streams. This model is also capable of computing the annual erosion amount and sediment yield in the individual sub-basins

土壤侵蚀与输沙的分布式模拟
一个数学模型用于估计Nestos河流域(Toxotes,色雷斯,希腊)出口的降雨和径流造成的年泥沙产量,生态上有趣的Nestos三角洲存在于此。该模型适用于Nestos河流域(838平方公里)的部分,位于三个水坝的下游。两座大坝(Thissavros和Platanovryssi)已经建成,而第三座大坝(Temenos)正在建设中。该模型包括三个子模型:降雨径流子模型、地表侵蚀子模型和河流输沙子模型。该模型还能计算出各子流域的年侵蚀量和产沙量
