Cotonou is the largest city in Benin, Africa with a population of 1.5 million. The city relies on groundwater wells, some with increasing levels of salinity (salts). Certain wells have been abandoned because they exceed the taste threshold for chloride. Future groundwater development must be managed so long-term threats to water quality are minimized while the rate of water production remains sufficiently high to serve the population. Our team developed a calibrated groundwater management tool with a user manual that demonstrates how to modify the model. This management tool allows agency personnel to assess the impact of present and future water development strategies. The tool also allows agency personnel to determine the flow pathways of groundwater under various well location and pumping discharge scenarios.
