GEPIC

GEPIC is a GIS-based agroecosystem model integrating a bio-physical EPIC model (Environmental Policy Integrated Climate) with a Geographic Information System (GIS). The GEPIC model can be used to simulate the spatial and temporal dynamics of the major processes of the soil–crop–atmosphere-management system.

The model has been used to study crop production, agricultural water uses, impacts of climate change on water and agricultural systems, virtual water and water footprint, biofuel-water relations on large scales (global, national, and river basin). It can also be used in other research areas e.g. water quality, N cycle, C cycle, water and wind erosion etc.

GEPIC is a public domain program, and as such may be used and copied free of charge for non-commercial uses. The current program is version 1.0.
