摘要
介绍了一个复杂的严格基于物理概念的水文/侵蚀数值模型InHM (Integrated Hydrology Model)的模型结构和控制方程.InHM通过求解水流在地表和空隙介质中的偏微分流动方程,而不是应用经验/半经验公式或回归关系,来模拟水文响应.模拟的水文响应结果被用来驱动一个泥沙搬运算法.InHM考虑的水文响应过程包括蒸发蒸腾、入渗、地表产流、地下水运动(饱和/非饱和)、地表水运动等.InHM考虑的地表侵蚀过程包括由于雨滴溅击和地表水流引起的泥沙颗粒侵蚀、搬运和沉积.
The model structure and governing equations of a rigorous complex physics-based hydrologic-response/erosion model, Integrated Hydrology Model （InHM）, are introduced. Instead of deploying empirical/semi-empirical equations and regression relationships, InHM simulates hydrologic-response based upon solution to the partial-differential equations governing water flow within porous media and on the surface. The simulated hydrologic-response was then employed to drive a sediment transport algorithm. Hydrologic-response processes considered by InHM include evaporatranspiration, infiltration, surface runoff generation, groundwater flow （ saturated/unsaturated）, and surface water flow. Erosion processes considered by InHM include detachment ,transport, and deposition caused by both rainsplash and hydraulic erosion.
