In this study, the relationship between water quality (as represented by major inorganic ion
concentrations) and land use characteristics is examined for a small river basin which runs …

To assess the influence of land use pattern on the major ion chemistry of river water,
seasonal changes in major ion concentrations were studied in the Shimousa Upland, Japan …

Recent research and monitoring undertaken by various institutions have emphasized
measurements of river-water quality. Based on the results, government agencies have set …

This study investigated the relationship between land cover and the water quality variables
in the rivers, which are located in the Yamaguchi prefecture of West Japan. The study area …

The quality of drinking water (tap, ground, and spring) in Toyama Prefecture, Japan was
assessed by studying quality indicators including major ions, total carbon, and trace metal …

Seasonal and spatial variations in major ion chemistry and isotope composition in the rural-
urban catchment of the Shigenobu River were monitored to determine the influences of …

This study was carried out to evaluate the quality of river water by analysis of land use in
drainage basins and by estimating the N budgets. The drainage basins of Shibetsu River …

Inland rivers play a key role in supplying water for domestic and agricultural purposes in
Asian arid inland basin. This paper investigates the chemical composition of precipitation …

We investigated the effects of natural environments and human activity on Lake Biwa,
central Japan. We determined the concentrations of 19 elements and the compositions of …

Researchers generally accept that land use types within a watershed closely relate with the
water quality characteristics of streams. Despite numerous studies investigating the …
