Hydrology of the Nile BasinElsevier, 01.01.1985 - 593 Seiten A wealth of hydrological, hydrometeorological, hydrometrical and other related data covering nearly all parts of the Nile Basin is presented in this volume. After an introductory chapter on the Nile's history, chapters cover: the physiography, topography, and climate of the different parts of the Nile Basin; rainfall on the Basin, evaporation from open surfaces, and evapotranspiration from cropped areas. Rainfall data for a 30-year period from 1938 to 1967 are summarized and analyzed; evaporation and evapotranspiration measurements are presented, analyzed and discussed. In the absence of actual measurements, attempts have been made to estimate them from a number of formulae using the available climatological normals. The results obtained are important for planning, design and management of water supply and control projects, especially for irrigation and drainage. The geology of the Nile Basin is briefly reviewed and its effect on groundwater potentials, quality and quantity is discussed. Surface runoff and discharge at the key stations is covered, and an extensive review given of existing water storage, control and conservation projects in the Nile Basin.Thus the volume contains an enormous amount of data that will be of great practical value to consulting engineers. It is a book which should be in the library of all hydrological institutes and universities. |
