ECOMSED 水动力和泥沙输运模型，它可以较为真实地模拟环流、温度盐度、粘性与非粘性泥沙的输运、沉积与再悬浮。包括以下几个模块：水动力模块、泥沙输运模块、风驱波浪模块、热通量模块和粒子示踪模块。-ECOMSED is a three-dimensional hydrodynamic and sediment transport model. The hydrodynamic module solves the conservation of mass and momentum equations with a 2.5-level turbulent closure scheme on a curvilinear orthogonal grid in horizontal plane and σ-coordinate in the vertical direction. Water circulation, salinity, and temperature are obtained from the hydrodynamic module. The sediment transport module computes the sediment settling and resuspension processes for both cohesive and noncohesive sediments under the impact of waves and currents. The hydrodynamic component is same as the ECOM3D/POM model.
