Visualizing and understanding the aquifer system based on reliable borehole data is increasingly essential in groundwater management and sustainable development. With the possibility of breaking down the wells, decision-makers got extremely concerned about finding the best location for drilling new groundwater wells. Therefore, three-dimensional hydrogeological modeling and visualization of the aquifer system can be used as a decision-aiding tool for selecting the optimum site for drilling new groundwater wells. To build an accurate and reliable 3D model based on geophysical and hydrogeological data, it is essential to develop a workflow methodology that considers the variety of these available borehole data. This method has been developed by a combination of well-logging data (Gamma-ray, SP, and Resistivity) and analyzing step-drawdown pumping tests for 79 groundwater wells, in addition to remote sensing data such as a digital elevation model (DEM) with a high spatial resolution and Landsat images to visualize the surface and subsurface of the study area. Several aquifer properties and characteristics are discussed in this study to help in selecting the optimal well location. Moreover, the 3D hydrogeological model is introduced to visualize the lateral and vertical distribution of the lithostratigraphic layers and to understand the effect of basement rocks on drilling new wells. Three specific suggestions are proposed to enhance the application and efficiency of this 3D modeling and to provide a reference for future applications and developments.
