理论建模和数值模拟将应用于河流形态的三个方面：黏性土壤中的切口沟道网络，水流在其上形成的泥沙河床的形成和有限振幅稳定性，以及水流剪切和压力作用下泥沙粒度的分选。泥沙运移和河流形态是各种土木工程和环境问题的重要因素。
英文摘要
Theoretical modeling and numerical simulation is to be applied to three areas in river morphology: incisional channel networks in cohesive soils, formation and finite-amplitude stability of sediment bedforms formed by flows over them, and sediment grain size sorting from flow shear and pressure forces. Sediment transport and river configurations are an important element in a variety of Civil Engineering and environmental problems.
