Title: Behavior and Training of Gash River
Author: Abbas Abd Alla, Ibrahim
Abstract: The study of the nine kilometers stretch in the neighborhood of Kassala town revealed that the River Gash is an ephemeral influent river. It usually flows from July to September. It has a braided pattern, with high sediment content, of 15200 p p.m., in suspension, and 56.3kg/sec. as bed load. Its bed has an average slope of 0.0013, while its banks are subjected to failure by toe erosion seepage and saturation. Discharge records from 1907 shows that Kassala was frequently affected by floods. Investigation of these floods indicated that average annual yield reached 650 M.M3 annual mean maximum discharges approached 360 M3/sec., while the extreme maximum recorded discharge was 770M3/sec. Training of the River Gash and protection of Kasha town by the existing spurs and dikes along the middle three kilometers reach, within the nine kilometers stretch, was critically examined. The main aim was to obtain a meandered channel, not only to pass the flood flows, but also to train the river and protect the town. The extension of spurs and dikes upstream and downstream of the existing ones, was found to be the best measure to fulfill these requirements.
