“…He also concluded that using station data as meteorological data source led to good and often best model efficiencies. Shaibu et al [47] used a simplified runoff model for the Black Volta basin using an adjusted monthly TRMM 3B42 product as input data and the results were encouraging (NS = 0.89).…”

“…The novelty in this study is the use of different or various optimisation methods and model performance measures for both calibration and validation, in order to assess the robustness and stability of the model in the study area. From the review of literature, it was realised that most hydrological models performed globally and locally in the sub-region more often used only one performance measure (mostly Nash-Sutcliffe (NS)) to assess the performance of the model, for example [3,20,47,54]. We believe that it is not good enough to only conclude on the efficacy of hydrological models just on the NS measure.…”

A lumped version of the conceptual HBV-IWS version (Hydrologiska Byrans Vattenbalansavdelning) hydrological model was applied on the Black Volta Catchment in the West African sub-region (a data-scarce catchment) to investigate the performance of the model in the study area. In assessing the robustness of the model and how well it performs in the study area, different optimization methods were used. The Robust Parameter Estimation (ROPE) algorithm was used to generate and calibrate 10,000 best parameter sets in a computer framework with initially set model parameter ranges. The model performed well with an average NS of 0.75 and 0.6 for calibration and validation respectively for subcatchments Lawra and Chache. The performance also improved when a higher weight was given to the low-flows during the optimization. Results also show that the model reacts well to precipitation signals. For a proper management of the water resources and hydropower in the West Africa sub-region and for good policy decisions and investments in water related projects, a robust hydrological model would be essential and crucial for the Black Volta Catchment. The results of this study will be an essential input to a further study in assessing the effects of climate change on the hydrology of the West African sub-region.

“…These changes can have direct or indirect impacts on the hydrological cycle of the watershed. According to [7], there is inter-annual variability in rainfall and runoff and the mean monthly potential evapotranspiration over the Black Volta.…”

“…In some extents, impacts on the watershed of forest changes or land use changes can be as important as those from climatic variability. A key variable that can affect runoff generation could be land cover change [7]. Climate and land use change already have a large impact on the hydrological cycle in West African countries [8][9][10].…”

Abstract:The Bui hydropower plant plays a vital role in the socio-economic development of Ghana. This paper attempt to explore the combined effects of climate-land use land cover change on power production using the (WEAP) model: Water Evaluation and Planning system. The historical analysis of rainfall and stream flow variability showed that the annual coefficient of variation of rainfall and stream flow are, respectively, 8.6% and 60.85%. The stream flow varied greatly than the rainfall, due to land use land cover changes (LULC). In fact, the LULC analysis revealed important changes in vegetative areas and water bodies. The WEAP model evaluation showed that combined effects of LULC and climate change reduce water availability for all of demand sectors, including hydropower generation at the Bui hydropower plant. However, it was projected that Bui power production will increase by 40.7% and 24.93%, respectively, under wet and adaptation conditions, and decrease by 46% and 2.5%, respectively, under dry and current conditions. The wet condition is defined as an increase in rainfall by 14%, the dry condition as the decrease in rainfall by 15%; current account is business as usual, and the adaptation is as the efficient use of water for the period 2012-2040.
