摘要

In this paper, we used Green-Ampt and Parlange models to simulate infiltration responses for five different typical European top soils. Different rainfall distribution types and surface storage capacity, with the same cumulative rainfall amount and rainfall interval were used to design four scenarios for simulating heavy rainfall condition in case 1. While nine scenarios were designed by different ponding depths and different functions of ponding depth with time, to simulate ponding condition in case 2. Numerical experiments showed that the sequence of soil infiltration capacity is coarse & fine & very fine & medium & medium fine, consistent to the sequence of soil saturated hydraulic conductivity Ks. Other variables, such as cumulative infiltration, runoff and the time when runoff occurs are also affected by Ks, soil water retention curve, and surface storage capacity. The parameters of soil water retention curve are the next most important factor. And more, hs is also important for Green-Ampt model. Surface storage capacity can not only reduce the runoff but also lag the time of runoff occurrence. Reponses under different rainfall conditions vary largely, so exterior conditions should be paid more attentions when using Green-Ampt model. However, responses under different ponding distribution vary less. Thus, if ponding depth distribution is complex, constant ponding distribution type can be assumed for simplifying when Parlange model is used.
