long duration
Examples
- Based on the hydrodynamic theory , the riverbed deformation process of all reservoir area during long duration is investigated by using of computer numerical simulation . in the meantime , based on one dimensional sediment model , the simulation of the longitudinal scouring and sedimentation and lateral deformation in reservoir tidal flat and mainstream are researched . the quasi - two dimensional sediment numerical model forecasting longitudinal scouring and sedimentation and lateral deformation in reservoir and river are established
应用水动力学理论，以计算机数值模拟为手段，主要考虑长历时全库段的河床变形过程，在一维泥沙数学模型基础上，同时考虑水库滩槽纵向冲淤和横向变形的模拟，着重建立可以预测水库及河道纵向冲淤及横向变形的准二维泥沙数学模型。
