Modelling Land Use Change and Nonpoint Source Pollution Potential Using Remote Sensing and Geographic Information System Technology (open access)

Modelling Land Use Change and Nonpoint Source Pollution Potential Using Remote Sensing and Geographic Information System Technology

In this study Geographic Information System (GIS) technology was integrated with remote sensing techniques in order to determine the potential for nonpoint source pollution in the Lake Palestine and Cedar Creek Reservoir watersheds of North Central Texas. The Universal Soil Loss Equation was used to determine soil erosion potential from the watersheds, and export coefficients were used to estimate nutrient loadings into the reservoirs.
