PCARES (Predicting Catchment Runoff and
Soil Erosion for Sustainability)

• GIS-assisted physical model of a landscape
• Simulates hydrology and sediment transport
• Locate soil erosion Hot Spots
• Predicts the impact of land use change on soil
  erosion, water quantity and water quality in a
  watershed
