Analytical approximation to the solutions of Richards' equation with applications to in®ltration, ponding, and time compression approximation
نویسندگان
چکیده
A recent approach to solve Richards' equation is further improved. This approach brings understanding into the physical processes of in®ltration and ponding. 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 ponding time. Ó 1999 Elsevier Science Ltd. All rights reserved.
