Abstract

The seasonal variation of the quality of stream water in a snowy temperate area, where rain or temporary warming can cause frequent melting at the surface of snow cover, even in mid‐winter, was studied. Monthly runoff is highest in the snowmelt seasons March and April, and lowest in November. Since floods in the rainy season or in the autumn rainy period take place irregularly, they contribute little to monthly runoff. In winter, as with the snowmelt season, the proportion of HCO~3~^−^ in stream water is relatively low, while the proportions of Cl^−^, NO~3~^−^ and SO~4~^2−^ are relatively high. In mid‐winter and during the snowmelt season, the amount of each ion clearly indicates that stream water quality is strongly influenced by snow meltwater. Copyright © 2003 John Wiley & Sons, Ltd.

## Abstract The near‐stream zone has received increasing attention owing to its influence on stream water chemistry in general and acidity in particular. Possible processes in this zone include cation exchange, leaching of organic matter and redox reactions of sulphur compounds. In this study the i
