Improving Groundwater Recharge Estimates And Groundwater Management For The Cuvelai-Etosha Basin

AbstractVarious studies have shown that the use of tracer techniques such as the chloride mass balance (CMB) and stable isotopes’ methods are suitable and good practical approaches to estimate groundwater recharge. Estimating groundwater recharge improves the understanding of groundwater availability in making informed strategies for groundwater resources management. Using secondary data, this study estimated groundwater recharge within the Cuvelai-Etosha Basin (CEB) via the CMB and stable ...

Estimation Of Evaporation Losses Based On Stable Isotope Composition Of Water In The Calueque-Oshakati Canal, Namibia.

ABSTRACTThe open concrete-lined Calueque-Oshakati canal has been operational since the 1970s, carrying raw water from the Calueque Dam on the Kunene River in the Southern region of Angola to the Central Northern region of Namibia. This raw water is conveyed to the purification plants along the canal, where it is purified before distribution to towns and villages through pipelines. This thesis presents the findings on the estimation of evaporation losses using the stable isotopic composition o...

Assessment Of Floodwater Harvesting Infrastructures In The Namibian Cuvelai-Etosha Basin

AbstractThe Cuvelai-Etosha Basin lies in north-central Namibia and due to the prevailing climatic situation, the basin is dominated by strong seasonal and annual variations of either very dry conditions with drought or heavy flooding in certain years.A growing population in the Cuvelai-Etosha Basin has resulted in increased demand for water for daily use and agricultural activities. Floodwater Harvesting Infrastructures are considered to be a more effective way to solve those problems. Hence ...
