Conceptual Remarks on The Solutions of Prospective Problems for The Development of El-Wadi El-Gideed Wells Field.(Dept.C)

Abstract

Egypt as an arid zone has utilized irrigation from the earliest times to grow various crops and continually establish the roots of civilization allover the country. Irrigated agricultural development and reclamation of new land have highest priority in the present world where production of foodstuffs must keep pace with a very rapidly increasing population rate. Since great attention was directed toward El-Wadi El-Gideed area, extensive research and field works were carried out in the attempt to reclaim vast areas there and converted from plain gel low desert to productive green lands. This is for a sound ground water basin development leading to well developed agricultural zone with truly economic water development controled by systematic management, avoiding any striking discrepance between the major anticipated objectives of the project. Most of the prospective problems and expected difficulties are fully identified and proposed solutions are domonstrated. Conceptual remarks were focused on: oonstructional precautions and selection of deep-well turbine pumps, hydrologic equilibrium, . excessive well 1088es, safe yield and overdraft, excessive discharge (over-pumping) from an aquifer and specific capacity of a well, the drawdown and recovery curves, the rate of recovery in pressure wells, style=text-decoration: underline; confined aquifer and multile interfering well systems, corrosivity of pumped water and precautions against pipes corrsion and finally the deterioration of ground water quality. Several local examples accomodating with the environmental circumstances of the area under investigation were displayed and proposed analyses and procedures for satisfactory solutions were discussed and fully represented. The research paper le concluded by itemizing few of the anticipated gains as well as the prospective side effects of the over-pumping activities under extensive rates. Pew concluding remarks and recommendations are also provided; hoping to be, along with the context material presented, to be useful to all those engaged generally in irrigation and water development and those who are doing their extreme efforts to achieve anticipated progress in El-Wadi El-Gideed, Egypt.
