An index to characterize the spatial distribution of land use within watersheds and implications for river network nutrient removal and export

摘要: The spatial distribution of land use and associated nutrient inputs may influence the efficacy in-stream removal however, effect source location on N watershed export has not been quantified. We present skewness index, a metric to quantify within watersheds. Using this index river network nitrogen model, we quantified varying developed two watersheds export. quantity as well runoff affected Because is bypassed when sources are skewed towards mouth, alone can double aquatic removal. Nutrient distant headwaters maximized which in turn reduce
