A Review of Climate Change Scenarios and Preliminary Rainfall Trend Analysis in the Oum Er Rbia Basin, Morocco

"The paper reviews the existing tools methods and general literature which deal with the construction of climate change (CC) scenarios and with the assessment of impacts of these scenarios on water resources. It further examines the existing CC predictions specific to Morocco. The paper further describes the publicly available hydrometeorological time series data, which could be used to quantify the future CC scenarios for a river basin in Morocco (Oum er Rbia) and a smaller irrigation scheme within it (Tadla), located in the western part of the country. The data indicates that the impact of future CC on water resources at smaller scales such as smaller river basins, specific water resources and irrigation systems has to date not been properly addressed and, therefore, constitutes a niche for immediate research."
