The coupled SWAT-MODSIM model is a program that links the SWAT and MODSIM models
for better integrated water resource planning and management. Optimal water allocation among
competing users including hydropower generation is missing in SWAT. The main feature of MODSIM
DSS is in allocating available water resources to different users optimally, irrespective of what
sources they come from. That is why the idea of coupling SWAT and MODSIM as two powerful tools
for modeling both water availability and water allocation (management) is a very attractive idea.
