Modeling the impact of climate change on water resources and soil erosion in a tropical catchment in Burkina Faso, West Africa

Subsurface sources contribute substantially to fine‐grained suspended sediment transported in a tropical West African watershed in Burkina Faso

“…They found a shift of the dominant source of sediment from agricultural soil erosion to accelerated erosion of stream banks driven by increased river discharge in the upper Mississippi River. A recent study on land use change in a subwatershed of our Burkina Faso study area shows that discharge has possibly increased by 25% between 1990 and 2015 due to a significant conversion of savanna to agricultural land (Op de Hipt et al, ). Furthermore, the findings of Op de Hipt et al () show that climate change may additionally increase discharge in the range of 19% to 36.5% between 2021 and 2050.…”

Furthermore, the findings of Op de Hipt et al () show that climate change may additionally increase discharge in the range of 19% to 36.5% between 2021 and 2050. Because of the study basin characteristics with only moderate to low upland erosion rates, the measured and forecast increasing discharges are likely to increase sediment loss not only from agricultural land but also from river bank erosion in the future.…”

Multi-Site Statistical Downscaling Method Using GCM-Based Monthly Data for Daily Precipitation Generation

“…(2) A linear relationship between P_mon and P(W|D) for each month for all sites was assumed so that the wet-following-dry transition probability can be estimated for future years, i.e., P(W|D) = a+b × P _mon (7) (3) It was assumed that the probability of occurrence of a wet day, P(W), was proportional to P(W|D). In other words, since [59]:…”

“…For future climate change projections, Global Climate Models are widely used in the fields of hydrology, biology and environmental studies. In hydrology, they are often used as inputs for hydrological models to evaluate the impact of climate change on runoff [2,3], sediment yield [4,5] and soil erosion [6,7]. However, due to the incomplete understanding of the physical mechanism of climate change and the large amount of calculations, GCM output often has coarse spatial and temporal resolutions.…”

Impact of extreme events on conversion efficiency of wave energy converter

“…HadCM3 model was developed by Gordon et al 49 at the Hadley Centre in the United Kingdom which considered the influence of both atmospheric and oceanic parameters and includes the impact of aerosol on the climate. The model was widely used for different predictive studies such as estimation of climate change impact on groundwater recharge in arid regions of Iran, 50 water availability for different types of consumption in Tanzania, 51 water resources and soil erosion in Burkina Faso, West Africa, 52 paddy irrigation water requirements in Sri Lanka, 53 estimation of future distribution of plant species in the European continent, 54 and change in Arctic sea ice thickness and area for the future time slabs. 55 HadCM3 does not include flux adjustment due to its stable control climatology.…”
