A Study on the Response Characteristics of Snowmelt Runoff

Abstract

In this paper, by applying the filter-separation AR method, the response characteristics and non-linear separation laws of rainfall in snow season are compared with those of non-snow season and discussed. The results of analysis are as follows:(1) There is no significant difference between the response function of inter flow system in snow season and those of non-snow season.(2) The response function of groundwater flow in snow season shows an about half peak discharge and continues a longer period than those of the non-snow season.(3) In snow season more effective rainfall are supplied to the groundwater system than non-snow season.
