The Toudaogou River Basin is one of the many rivers with high annual runoff volume but without glacier meltwater feeding in arid area in China. It is of popular sense for utilizing water resources and constructing water conservancy projects in the moderate and small drainage basins without glacier meltwater feeding in arid area in China to analyze the features of suspended silt discharge in the Toudaogou River Basin. The main factors affecting suspended silt discharge include the terrains, landforms, precipitation, flood, etc. In this paper, the data measured in the Toudaogou River Basin for more than 20 years were analyzed using the principle of mathematical statistics. It was found that an annual suspended silt discharge in such arid drainage basin could be as high as more than 20 times of the average value, and these features of suspended silt discharge could be referred in surveying and designing water conservancy projects.
