Abstract
The development of water resources is a significant part of the integrated
development of many countries. Therefore, there is a continual need for
the comparison of water demand and available water resources.
The Government of Egypt initiated a national development plan aiming
to create new communities away from the Nile valley and Delta to absorb
a portion of the growing population and to provide job opportunities for
young generations. These development activities will need a sustainable
source of water supply.
Marriout Irrigation District was chosen as the study area because it
represents the Egyptian irrigation system at the tail end and contains all
relevant issues that would have to be analyzed in an irrigation system in
Egypt. .
Existing situation of Marriout Irrigation District, water requirements are
completely satisfied during four months. For the remaining eight months,
water requirements are partially satisfied. The water requirement is
satisfied by 91% in January. Water supply suffers a severe shortage in
February, March, April, May, June, July and August when the water
demand is only satisfied in September, October, November and
December.
Thus to solve water problem in Marriout Irrigation District an integrated
management of water resources could reduce water interruption and lead
to a sustainable development. Under the limited water resources, the
optimum utilization of water resources is most important. Thus a
framework for analysis and a computational framework have been
developed. Problems and triggers, boundary conditions, socio-economic aspects and questions to be answered by the study have been specified.
A general goal and a set of objectives and criteria have been formulated.
Four objectives have been specified concerning the following aspects:
(I)Economic; (2)Social; (3)Efficiency of water use and (4)Sustainability
as well. Seven scenarios of water resources management were proposed
in the study area in order to evaluate and develop Marriout Irrigation
District.
from the analysis it can be concluded that the existing situation gives the
best opportunity for agro-industrial output and provides with the best
insurance of food security. Proposed scenario which considers study area
has become pressurized irrigation system however insures best
agricultural output, guarantees higher income level and improved
irrigation efficiency in the meantime. This indicates that the change from
gravity irrigation to pressurized system is the major factor in obtaining
better production, better returns and better water use efficiency.
