Across Africa, perennial drainage density as a function of mean annual rainfall defines three regimes separated by threshold values of precipitation. This nonlinear response of drainage to rainfall will most seriously affect regions in the intermediate, unstable regime. A 10% decrease in precipitation in regions on the upper regime boundary (1000 millimeters per year) would reduce drainage by 17%, whereas in regions receiving 500 millimeters per year, such a drop would cut 50% of surface… 
Projected impacts of climate change on groundwater and stormflow in a humid, tropical catchment in the Ugandan Upper Nile Basin
General comments The paper addresses climate change impact on water resources in the Upper Nile Basin. SWAT model is used for hydrological response simulations, while 7 climate models are considered
Sensitivity of global river discharges under Holocene and future climate conditions
A comparative analysis of global river basins shows that some river discharges are more sensitive to future climate change for the coming century than to natural climate variability over the last
Impact of climate change and irrigation development on hydropower supply in the Zambezi River Basin, and implications for power sector development in the Southern African Power Pool
ion points The irrigation abstraction points in the model are implemented as irrigated catchment areas, with a transmission link from the relevant water source and a return flow for any unused runoff
Climate Change Impacts on African Rangelands
Even though Africa has contributed the least to global greenhouse gas emissions, it is considered the continent most susceptible to climate change impacts because of 1) the large proportion of people
Climate Change and Water Supply
Climate change will have major implications on the global water cycle. Precipitation will increase in some regions but decrease in others. Snow will melt earlier in the season, and many glaciers are
Exposure of Africa's freshwater biodiversity to a changing climate
Anthropogenic climate change and increased human water use are widely expected to place great stress on available water resources across Africa and Madagascar, but the effects of these changes on
Review on Impacts of Climate Change on Watershed Hydrology
The natural environment has been highly influenced by human beings since the industrial revolution that impact human activities. There is highly increase in global temperature and the amount and
The impact of climate change on groundwater recharge and runoff in a humid, equatorial catchment: sensitivity of projections to rainfall intensity
Abstract Projected warming in equatorial Africa, accompanied by greater evaporation and more frequent heavy precipitation events, may have substantial but uncertain impacts on terrestrial hydrology.


On the sensitivity of drainage density to climate change
Drainage density reflects the signature of climate on the topography and dictates the boundary conditions for surface hydrology. Hence defining the relationship between drainage density and climate
SUMMARY Daily sampling of suspended sediment in the flooding Orange River was carried out at Alexander Bay from late February to the end of May 1988. Coupled with simultaneous measurements of water
Mean seasonal and spatial variability in gauge‐corrected, global precipitation
Using traditional land-based gauge measurements and shipboard estimates, a global climatology of mean monthly precipitation has been developed. Data were obtained from ten existing sources, screened
Intensity and spatial extent of droughts in southern Africa
The standardized precipitation index allows for monitoring the intensity and spatial extent of droughts at different time scales. We used it to do a retrospective analysis of the spatial extent of
Reconstructing Past Climate from Noisy Data
The centennial variability of the NH temperature is underestimated by the regression-based methods applied here, suggesting that past variations may have been at least a factor of 2 larger than indicated by empirical reconstructions.
Where do channels begin?
The closer channels begin to drainage divides, the greater will be the number of channels that occupy a unit area, and consequently the more finely dissected will be the landscape. Hence, a key
