Spatial variation impact of landscape patterns and land use on water quality across an urbanized watershed in Bentong, Malaysia

Landscape patterns and land cover changes critically impact the hydrological cycling of pollutants and affect receiving water quality significantly. Understanding spatial distribution and allocating water pollution sources are vital elements in implementing effective water resource management practi...
