Abstract

This paper gives mathematical details and sample applications of SWAGMAN Farm (SWAGMAN, SaltWater and Groundwater Management), a farm-scale hydrologic economic model that integrates agronomic, climatic,irrigation, hydrogeological and economic aspects of irrigated agriculture. The model is capable of determining optimum mix of land use to keep watertable and soil salinity within acceptable limits while maximising the economic returns. Alternatively, the model can simulate water and salt balance and economics of a given cropping preference. Web-based and Geographic Information Systems versions of the model are available for integration with the environmental reporting systems of the irrigation areas.
