Assessing climate change impact on the hydropower potential of the Bamboi catchment (Black Volta, West Africa)
<p>This study evaluates the impact of future climate change (CC) on the hydropower generation potential of the Bamboi catchment (Black Volta) in West Africa using a conceptual rainfall-runoff model (HBV light) and regional climate models (RCMs)–global climate models (GCMs). Two climate simulat...

<p>This study evaluates the impact of future climate change (CC) on
the hydropower generation potential of the Bamboi catchment (Black Volta) in
West Africa using a conceptual rainfall-runoff model (HBV light) and
regional climate models (RCMs)–global climate models (GCMs). Two climate
simulation datasets MPI-ESM-REMO (CORDEX) and GFDL-ESM2M-WRF (WASCAL) under
RCP4.5 were applied to the validated hydrological model to simulate the
catchment runoff. Based on reference and future simulated discharges, a
theoretical 1.3 MW run of river hydro power plant was designed to evaluate
the hydropower generation. Hydrological and hydropower generation changes
were expressed as the relative difference between two future periods
(2020–2049 and 2070–2099) and a reference period (1983–2005). The climate
models' ensemble projected a mean annual precipitation increase by 8.8 %
and 7.3 % and discharge increase by 11.4 % and 9.735 % for the
2020–2049 and 2070–2099 periods respectively (for bias corrected data). On
the contrary an overall decrease of hydropower generation by <span class="inline-formula">−</span>9.1 % and
<span class="inline-formula">−</span>8.4% for the 2020–2049 and 2070–2099 periods was projected
respectively. The results indicate that projected increases in discharge
should not solely be considered as leading to an increase in hydropower
potential when prospecting climate change impact on hydropower.</p> |
