Nutrient Concentrations in Different Land Use Types along River Riana, a Tributary of the Kuja Migori River Kisii – Kenya

Jomo Boston Siriba, Zipporah Gichana & Reuben Omondi · International Journal of Environment and Climate Change · 2026

River systems draining catchments with diverse land use activities are increasingly vulnerable to nutrient enrichment, which poses significant risks to aquatic ecosystem health and downstream water quality. This study assessed spatial and temporal variation in nutrient concentrat...
