Soil and Water Assessment Tool - Mississippi-Atchafalaya River Basin (SWAT-MARB)
Abstract: The Soil & Water Assessment Tool is a small watershed to river basin-scale model used to simulate the quality and quantity of surface and ground water and predict the environmental impact of land use, land management practices, and climate change. SWAT is widely used in assessing soil erosion prevention and control, non-point source pollution control and regional management in watersheds. ORNL and ANL contribute to this model.
Multiple Programming Languages
General Modeling Type:
Hybrid / other: Geospatial Bio-Physical Process Based Hydrological Model
Primary analytical purpose:
System level: Analysis of the effects of bioenergy and bioproduct technologies and feedstock on the landscape or relate markets. System level modeling examines effects outside the direct supply chain.
Secondary analytical purpose:
Bio-physical assessments: Assessment of potential feedstock resources based on the bio-physical properties of the feedstock/landscape and/or technical assessment of resources based on supply chains can access.
- Environmental Productivity (feedstock-related, e.g., NPP or yield)
- Soil Quality
- Water Impacts (quality and/or quantity)
