报告内容:Hydrologic processes are irreversible at space and time scales that are of practical interest. The irreversibility produces entropy. At steady state the entropy of a hydrologic system becomes maximum. From a statistical perspective, the maximum entropy production is the most probable state. When it rains in a watershed, part of the rainfall satisfies abstractions, such as interception, detention and depression storage, and evaporation; part enters the soil and percolates downward; and part, called rainfall excess, runs off the ground.
