STUDY ON THE MATHEMATICAL MODEL OF NON-STEADY WATER-SAND MOVABLE BED OF SEDIMENTATION RESERVOIR

Based on the river dynamics and sediment movement, the quasi two-dimensional sedimentation model is established simulating the relationship between the turbulent mixing in flowing water and sand movement. The model which is constructed on the basis of sand continuity equation and riverbed deformation equation have overcome the deficiency in the former theory, in which the formulas for calculating the sand carrying capacity of flow, dynamic tough force of movable bed, sediment motion and exchange, sediment composition are more accurate and reliable. The Model has laid a scientific basis for the study of sedimentation reservoir operation mode.
