Welcome to the Hydrology in Sub-Saharan Africa Portal
Nowcasting in Sub-Saharan Africa
This portal is designed to help forecasters in Sub-Saharan Africa to predict severe convective storms over the next few hours using near-real time satellite data — a process known as nowcasting. It has been developed by UKCEH scientists working in partnership with forecasters and researchers in Africa and the UK. The portal has been developed under a series of projects funded by the Natural Environment Research Council (NERC), UK Research and Innovation (UKRI), and the Foreign, Commonwealth and Development Office (FCDO).
Projected future changes in river flows across West Africa
The data presented in this portal shows gridded hydrological model estimates of projected future changes in monthly mean river flows (m3s-1) and changes in annual maximum river flows (%) at a ~10 km resolution across West Africa. In order to assess the impact of projected climate change on river flows during the high flow season across West Africa (August to November), resulting from the rainy season in July to September, changes in monthly mean river flows were estimated for each CMIP5 and CMIP6 ensemble member. Changes are calculated between historical and projected future periods using CMIP5 climate model data (hydrological change is calculated between two 30–year periods: 1970–1999 and 2005–2099) and CMIP6 (change is calculated between 1970–1999 and 2015–2100).
