Abstract: In Mediterranean coast, North Africa both fresh groundwater and surface water supplies are insufficient to meet the expected increases in water demand.Wise strategies for water development have to be establishing a fully utilize the surface and groundwater resources at economic costs.Therefore, detailed groundwater investigations will be undertaken aiming to elucidate the principal hydrogeological aspects of the areas; West of Suez Canal in Egypt and Derna NE Libya.As a basic requirement, the groundwater of this areas is evaluated for different purposes.Mismanagement of groundwater in the coastal areas leads to water quality deterioration due to saltwater intrusion.Studying saltwater intrusion and up-coning phenomenon is mandatory requirements for groundwater management in coastal aquifers.The Pilot area of Libya concluded that the flow in fractured media and saltwater intrusion.The results are promising to predict the aquifer response against changing the pumping rates.the drawdown in groundwater levels were found to be 0.142 and 0.4m which led to up-conning of values 5.68m and 16 m.due to pumping rate of 10 and 20 l/s respectively.Based on groundwater data water wells, water productivity maps and digital elevation models (DEM) were used in simulating the groundwater flow in the study areas and by using the Herzberg Equation and other governing equations, the up-coning was estimated.The Pilot area of Egypt ended to construct allowable rate map.Prototype of mobile application is prepared for allowable pumping rate and EC / Crop salinity stress.
