About This Book

A technical survey of the Nile and its basin that maps the river's course, slopes, velocities, tributaries, and catchment areas, and analyzes seasonal discharges and climate. It reviews major lakes and channels—Victoria, Albert, the White, Blue and Atbara systems—and the Sudd and branch streams, with measured sections, gauge data, and maps. Practical chapters discuss soil, basin and perennial irrigation, flood behavior and protection, and proposals for dams, reservoirs and inter‑basin works to secure perennial supply and flood control. A final contribution treats Egypt's oases and regional geology, detailing rock formations, stratigraphy, and economically useful materials.
