Formation process of streamwater quality in small mountainous forested basin

Abstract

This study focused on investigating the formation process of streamwater quality in small mountainous forested basin. Streamwater and soil water quality were observed and all solutes were classified into three types. In order to comprehend the formation process of the streamwater concentration, typical two solutes, NO₃^--N and SiO₂ were picked up and the relationships among the structure of runoff components and both streamwater and soilwater concentrations were investigated. The roles of runoff components in the formation process of streamwater concentrations were qualitatively discussed.
