The major issues concerning water development and management include water conservation and the efficiency of water use, cost recovery, social and environmental factors. So continuous monitoring is essential to evaluate the reclamation impacts on the groundwater potentiality such as Esna Area. The main objective of this work is to determine the new development areas in Esna during the period from 1984 to 2011 using remote sensing technique. The impacts of the present and future development have been evaluated by using the two-dimensional numerical groundwater flow Simulation Package (visual modflow 4.2). The package is used to construct and calibrate a numerical model that can be used to simulate the response of the aquifer in the study area under implementing different management alternatives in the form of changes in piezometric levels and salinity. From land use maps of the study area in the year 2011, a lot of changes in development areas especially out the border of the old land were observed. The change in land reclaimed area was estimated with 44% in the period from year 1984 to 2011. This development accompanied with draw down about 2.5 meters through this period of time. The authors recommend applying different kinds of change detection technique on the study area. Comparing between results, continuous monitoring of the development area is highly recommended.
