The dam is comprised mainly of a zoned earthfill embankment of 50.2m maximum height and a crest length of 2649m. Outlets consist of a concrete intake structure, a ‘Dry tower’, a D-section concrete conduit under the embankment, a spillway with 100m wide ogee crest and a discharge channel excavated in rock.
The dam has an embankment volume of about 4Mm3. The project, which includes the construction of Nora weir, is a masonry structure with flood embankments on the flanks and a combined volume of 18,229m3. Water from the dam would be expected to benefit irrigation schemes in Marsha and other surrounding commercial farms.
