The Volta Basin covers 400 000 km of the West-African Savanna. Agriculture is the dominant ecnomic activity. Given the extremely unreliable rainfall, irrigation development is seen as an obvious strategy to increase agricultural production. Irrigation development is mainly linked to the construction of small and medium sized reservoirs. The potential use of groundwater for irrigation is a very important issue. In this study, we present an evaluation of the conjunctive use of surface and groundwater in a representative small reservoir-irrigation system. The physical processes are modelled with WaSiM-ETH. The physical boundary conditions needed for the optimization model are then passed on to the optimization model written in GAMS, which then simulates the capture and utilization of runoff in small reservoirs. Water can be withdrawn for irrigation, or stored. Irrigation water can also be pumped from the underlying aquifer, and pumping costs are modelled as proportional to the distance to the water table.

We describe the development, calibration and preliminary application of a dynamically coupled economic–hydrologic simulation–optimization model ensemble for evaluating the conjunctive use of surface and groundwater in small reservoir-based irrigation systems characteristic of the Volta Basin, Africa. We focus on a representative small reservoir irrigation system located in the Antakwidi catchment in Ghana. The model ensemble consists of the physical hydrology model WaSiM-ETH and an economic optimization model written in GAMS. Results include optimal water storage and allocation regimes for irrigated production, given conjunctive surface water and groundwater systems. The goal of our research, conducted within the GLOWA Volta project, is to develop a decision support system for improving the management of land and water resources in the face of potential environmental change in the Volta Basin.
