Project description
This feasibility study for the design of reservoirs in Morocco involved several typical solutions: buried and surface reservoirs both, of either circular or rectangular section, and with capacities for 500 m3, 1.000 m3, 2.000 m3, 2.500 m3 and 5.000 m3. The structural solution to all possibilities was to use reinforced concrete, combining retaining and structural walls and also inner columns. The main constraint was to develop an optimisation of the structures according to their volume, i.e. number of compartments and necessary intermediate columns. This study allowed to have a close estimate of costs and visual impact for each reservoir, according to the shape, location, volume and number of compartments.
The reservoirs were designed to address the issue of insufficient irrigation water supply of the country. The dimensioning of the infrastructures was therefore based on the in situ characteristics, to determine reservoir volumes appropriate to the actual conditions. The goal of the study was to provide a variety of alternatives, according to the crops and areas in need of irrigation. The various solutions were presented according to rootstock type, watering efficiency, crop coefficients, reference evapotranspiration and hydraulic conductivity, among other parameters.
The study presented surface and buried reservoirs of circular and rectangular shape, with volumes ranging from 500 m3 to 5.000 m3.
