GIS-based pollution hazard mapping and assessment framework of shallow lakes: Southeastern Pampean lakes (Argentina) as a case study
The assessment of water vulnerability and pollution hazard traditionally places particular emphasis on the study on groundwaters more than on surface waters. Consequently, a GIS-based Lake Pollution Hazard Index (LPHI) was proposed for assessing and mapping the potential pollution hazard for shallow...
