Flood and Hydrological Analysis: Fish River Catchment

The Fish River catchment in Namibia is an area of concern to the Government as it is a flood prone area having registered very high floods, causing extensive damage to the town of Mariental and the irrigation schemes downstream of Hardap Dam. Measures needed to be put in place to curb further damage as the catchment undergoes its natural flood cycle. The system was modelled, and various mitigation measures were analysed and suggested for the area.

Water Availability Assessment for the Lunsemfwa Catchment

In this project an analysis was performed to determine if there was enough water to support an irrigation scheme in the upper Lunsemfwa Catchment in Zambia. The project was being developed by Nordzuker. The analysis yielded significant impacts on downstream users including the Lunsemfwa hydropower scheme and infrastructure interventions to ameliorate yield impacts were considered too expensive to support the irrigation water requirements.
