摘要：

A recent approach to solve Richards' equation is further improved. This approach brings understanding into the physical processes of infiltration and pending. In particular we apply it to analyze the standard hydrologic tool of Time Compression Approximation (TCA). We also suggest that the new approach provides a more reliable alternative to TCA, e.g. for predicting pending time. (C) 1999 Elsevier Science Ltd. All rights reserved.
