On flood control aspect,it has three functions of flood,detention and desanding,especially the function of desanding can slow down the rising speed of the river bed.

The floodplain on the lower Yellow River is of an important place for flood channel,flood detention,desanding and 1.

The influence of sediment subsiding on the index of the reservoir eutrophication;

Experiment study of flow s adjusting with flow board in sediment basin;

It is pointed out that adopting reservoir instead of sediment basin is feasible.

Grain-size characteristics of aeolian deposits in the shelterbelt of railway at Shapotou;

The data of sudden change of the main flow observed in a large-scale desilting basin located behind the main dike in the lower Yellow River indicated that the Markov probability prediction method can be used to predict the numbers of sudden change of the main flow with accuracy.

In this paper,according to the theory of over-satnrate transport concentration,the author puts forward calculation method of the whole process of silt movement on movable bed in desilting basin,including all calculations such as hydraulic factors,sedimentation rate,sedimentation feature and period etc.

The paper also provides structural drawings of the desilting basin and the storage tank with volu.
