Diffuse agricultural pollution is a leading contributor to surface water degradation, particularly in regions undergoing rapid land use change and intensification. In many developing countries, conventional assessment approaches fall short of capturing the spatial complexity cumulative nature multiple environmental drivers that influence vulnerability. This study addresses this gap by introducing Integral Index Vulnerability Contamination (IIVDC), spatially explicit, multi-criteria framework combines Analytical Hierarchy Process (AHP) with Geographic Information Systems (GIS). The IIVDC integrates six key indicators—slope, soil erodibility, use, runoff potential, hydrological connectivity, observed quality—weighted through expert elicitation mapped at high resolution. methodology was applied Guachal River watershed Valle del Cauca, Colombia, where pressures are pronounced.

The total maximum daily load (TMDL) system divides the watershed into unit basins for implementation and evaluates water quality by assessing whether targets have been achieved based on investigated data through continuous monitoring. River is influenced amount type of pollutants entering river, making monitoring, along with analysis evaluation, essential ongoing development policies systems aimed at improving quality. In this study, basic management were gathered analyzing pollution contributions main river (the Seomjin River) its tributaries, identifying major pollutant sources, conducting trend analyses. delivery Seombon D basin, one watersheds in South Korea, shows a rapid increasing (BOD, 1.2–2.4, 2020), which different from B Boseong River, also tributary. increase presumed to be due characteristics D, including inflow sources C, an upstream point. basin located middle that divide stream Korea A, B, E, F. This thought specific D’s influence C basin. contribution rate it was found area 38.42–120.08%), higher than self-purification capacity believed contributed improvement It manage sustainably improve Therefore, managing deemed necessary further enhance D.
