“…This relatively low baseflow is attributed to the short duration and high intensity of rainfall. In addition, in the arid context, there is little groundwater‐generated baseflow as the water table is generally below the level of the stream bed (Shahin, ). The greatest values of total water yield (run‐off plus lateral flow and baseflow) are observed from January to March (Table ).…”

The Merguellil catchment (central Tunisia) is a typical Mediterranean semi‐arid basin, which suffers from regular water shortage aggravated by current droughts. Over recent decades, the continuous construction of small and large dams and soil and water conservation works (i.e. contour ridges) have taken place within this watershed. However, little is known about the effect of these water‐harvesting systems on the water balance components of arid or semi‐arid basins. In this paper, we present the results of a study, which evaluates the impact of the contour ridges on water balance components and erosion at basin scale by using the soil and water assessment tool model (SWAT). Large dams were modelled as reservoirs, small dams as ponds and contour ridges as potholes that fill with water and increase the percolation into the aquifer. The model predicts that contour ridges produce annually a reduction of 32 and 21% in surface run‐off and river discharge, respectively, and an increase in aquifer recharge of 50%. At the same time, retention of a large proportion of entrained sediment (26%) was modelled.

“…Rainfall in Morocco is dominated by three main factors; winter cyclonic depressions, topography and convection. The precipitation, in general, decreases from north to south and from west to east (Shahin, 2007). Several studies have identified strong links with inter-annual precipitation variability and the NAO index (El Hamly and Sebbari, 1998;Knippertz et al, 2003).…”

“…The wind system is controlled by the SW Monsoon during July to September and a south-easterly directed wind regime (Shamal), which mostly prevails during the winter months. The annual variability of the solar radiation flux is 400e700 W m À2 , the mean wind speeds range from 5 to 8 m s À1 , and the potential evaporation is 2000 mm per year (Shahin, 2007). As the most prominent landform in eastern Arabia, the Oman Mountains obtain comparatively high amounts of precipitation due to the orographic effect: the weather station Saiq records an average yearly precipitation of 330 mm (Kwarteng et al, 2009).…”
