“…The results of the simulation process by applying the second proposed scenario (an increase in the daily pumping rate for all operating wells by 15 %) indicate that the predicted head at the year 2050 points to Table 2. These results are more or less comparable with the results of Youssef et al (2012).…”

“…Also, in the southwestern area, it is noted that the contour head is not affected by pumping during the simulation period. This may be attributed to the high values of hydraulic conductivity characterized to this locality (Youssef et al 2012).…”

“…This may be attributed to the presence of relatively high sand-clay ratio in the aquifer lithology with low groundwater recharge rate characteristic of these aquifer localities. Otherwise, the middle part of the model domain is not affected by this phenomenon due to the effect of the great aquifer thickness and the presence of thin clay layers rather than the geologic structural impact (Salem et al 2010;Gad et al 2011;Youssef et al 2012). Also, in the southwestern area, it is noted that the contour head is not affected by pumping during the simulation period.…”

Management of groundwater resources is very important for regions where freshwater supply is naturally limited. Long-term planning of groundwater usage requires method-based new decision support tools. These tools must be able to predict the change in the groundwater storage with sufficient accuracy and must allow exploring management scenarios with respect to different criteria such as sustainability and cost. So, a multi-objective optimization algorithm is used for groundwater management problem. In this paper, a genetic algorithm (GA) with two additional techniques, Pareto optimality ranking and fitness sharing, was applied to simultaneously maximize the pumping rate and minimize pumping cost. The methodology proposed herein has more Pareto optimal solutions, however, it is desirable to find the ones scattered uniformly over the Pareto frontier to provide a variety of compromise solutions to the decision maker. A groundwater resources management model is performed through a combined simulation-optimization model. This model is called the multi-objective genetic algorithm (MOGA) for optimization which combines the MODFLOW and GA. MOGA model applied in Wadi El-Farigh, Egypt, to develop the maximum pumping rate and minimum operation cost as well as to predict the future changes in both pumping rate and pumping operation cost. Model makes a feasible solution in groundwater management. Finally a compromise solution is presented from a set of Pareto optimal solutions to help the decision maker.

“…Steady increase of Egypt's population must be faced by enhanced sustainable of management of newly reclaimed soils, such as Wadi El-Natrun region. The groundwater in this region is considered as a unique water resource for the irrigation purposes (Youssef et al, 2012). During the recent years, increasing obstacles to meet the increasing the demands for domestic supplies and expansion in desert reclaimed soils has raised concerns for the sustainability of the groundwater resource (El Arabi, 2012).…”

Wadi El-Natrun region has recently undergone extensive urban and agricultural expansion. The main water resource for irrigation in this region is the groundwater aquifer. Extensive use of the aquifer water could cause a shortage in water storage and secondary salinization for this water, and a crop yield reduction. So, the objective of this study is to set efficient strategy to ensure long-term sustainability of the region's agricultural production. The electrical conductivity (EC) database of the baseline period (1966-2014), for twenty-seven wells of Wadi El-Natrun, were used to apply the time series statistical analysis to forecast EC data of the future period (2015-2050). Multitemporal forecasted EC data was used to classify the groundwater, detect the annual and periodical changes of groundwater salinity, and determine the periodical and annual water potential risk to salinity hazards. The results of the forecasted EC data indicated that the category of very salty groundwater dominated in the northern sector, while the moderately salty and salty groundwater categories dominated in the southern sector. The annual changes of groundwater salinity increased through the period of 2015-2050. The increase ranged from 0.95% to 1.35% with annual mean of 1.13% for the southern and northern sectors. The forecasted EC and an innovative and interpretative scale were conducted to estimate the periodical (PPRSH) and annual (APRSH) water potential risk to salinity hazard of the future period (2015-2050). The results indicated that the classes of no risk and moderately potential risk were dominant in the southern and northern sectors. Regarding the crop yield, in 1966, about 68.80% of the area under investigation produced 100% of citrus yield and 30.62% of area produced from 75 to 99% of the yield, while 89.9% of area produces 100% of tomato yield and 10.1 % of area produce between 75 to 99% of yield. Based on the forecasted groundwater salinity in 2050, the area of 100% of citrus production will be reduced to 1.41% and 52.64% of the area will produce less than 75%. At the same time, 16.44% of the area become out of citrus production. The area of 100% of tomato production will be reduced to 27.3% and 38.15% of the area will produce less than 50%.

Egypt is arid country in Africa, but has a large hydro geologic potential with many aquifers widely distributed throughout the country. Egypt is facing increasing water needs, demanded by a rapidly growing population, by increased urbanization, by higher standards of living and by an agricultural policy which emphasizes expanded production in order to feed the growing population. The effect of intrusion of seawater in coastal aquifer in western north coastal aquifer of Egypt is studied. The shape of the fresh-salt water interface and the water table profile is drawn by using Glover equation. The objectives of strategy of aquifer management are studied. The effect of increasing water table and salinity on the crop revenue is studied in Bahr Mashtoul canal command area as a case study by using OPDM model. The effect of the change in groundwater quantity and salinity from on the total gross revenue of total command area and on the gross revenue of each crop is calculated.
