River Regime with Special Reference to River Nile

Khalil, Mohamed Bakr

Regime theory of canals and rivers is reviewed and the concept of independent adjustment of slope, depth, and bed width was found irrelevent when applied to the River Nile channel, i.e., silt equation and flow equation. The silt equation relates the discharge, depth, and slope, and the median grain size of the bed. The factor of proportionality of the flow equation, a numerical constant, confirms that of Swiss rivers and is probably a universal constant. In the absence of a theoretical approach to regime of channels in alluvium, the Nile flow and silt equations, based on actual observations, seem to provide a suitable tool for rational calculations of current problems, e.g. resettling of the reach of the Main Nile disturbed by the construction of Aswan High Dam and design of the Jonglei canal.
