Groundwater development and sustainable agriculture in the White Volta Basin, Ghana
The project's overall aim is to strengthen the hydrogeological research capacity in Ghana and to develop reliable geological/hydrological models in the White Volta Basin in Ghana.
A numerical groundwater flow model will be developed to support quantitative assessments of the spatial and temporal variations in groundwater recharge as well as the possible impact of climate change/variability on groundwater budgets and the sustainability of groundwater resources for large scale irrigation. The project is carried out in close collaboration between research groups in Ghana and Denmark and includes training of Ghanaian PhD students.
The HGG-group's part of the project is primarily to support the data collection and the processing and inversion of the geophysical data. In this context a ground based TEM survey was conducted in November 2016 for evaluations/calibrations of a larger airborne TEM-survey for the geological/hydrological model.
The results of the geophysical and hydrogeological investigations will result in an integrated assessment of a cost-effective, sustainable, and resilient irrigation scheme involving the application of groundwater resources in the area.
