“…However, groundwater in bedrock The hydrogeological settings are mainly dominated by the lithological properties of the selected study area where porosity or secondary porosity (e.g., fracture) can provide space to store and trap water [30][31][32][33][34][35]. This information is included in the map of the hydrogeological unit to provide a conceptual hydrogeological model and characteristics [36][37][38][39].…”

Due to rapid urbanization, the development of megacities and metropolises worldwide is creating water scarcity, social-environmental risk, and challenges to the regions where water supply from rivers and alluvial aquifers is insufficient and unstable. Groundwater exploration in fractured bedrock of mountainous regions is thus a crucial issue in the search for substitute water resources. To achieve cost effectiveness on groundwater exploration, the use of comprehensive remote sensing (RS)- and geographic information system (GIS)-based models appears feasible. The required parameters selected and analyzed from the literature depend on the hydrogeological characteristics. This study intends to investigate and improve the proposed parameters and data sources upon those presented in the literature. A total of 17 hydrogeological units of concern was delineated from 105 complex geological formations of the geological sections and main rock types. The other parameters related to groundwater potential were derived from the digital elevation model and Landsat imagery. In addition, 118 drilling cores were inspected and in-situ well yield data from 72 wells were employed to assess the normalized groundwater potential index in the raster-based empirical GIS model with a higher spatial resolution. The results show that the accuracy of the interpretation of groundwater potential sites improved from 48.6% to 84.7%. The three-dimensional (3D) visualization of a thematic map integrated with satellite imagery is useful as a cost-effective approach for assessing groundwater potential.

“…Questions have been raised as to whether the underlying geologic setting could be a factor in flow losses in the study area. The presence of diabase dikes that intersect the river could act as impermeable boundaries to groundwater discharge (McSwain, 2009). Diabase dikes are high-angle, vertically intruded geologic features of mafic igneous rock with less thickness than length.…”

Mike Schlegel and Mr. Sydney Miller (formerly) of the Triangle J Council of Governments; and Mr. Mick Noland of the Fayetteville Public Works Commission. Their foresight and leadership in areas of water management as well as their assistance and support of this study have improved the understanding of the complex flow patterns in this reach of the Cape Fear River. The authors gratefully acknowledge the assistance provided by Ms. Ashley Hatchell and Mr. Tony Young of the U.S. Army Corps of Engineers, Wilmington District, during the study. Ms. Hatchell and Mr. Young collaborated with the U.S. Geological Survey on flow releases from Jordan Lake Dam during synoptic discharge measurement runs and other critical data-collection events. Progress Energy Carolinas provided assistance in this investigation. The authors acknowledge Mr. Mick Greeson and Ms. Robin Bryson for their support in the operation of a streamgage on the diversion canal adjacent to the Cape Fear River. Mr. Greeson and Ms. Bryson were instrumental in providing data concerning water withdrawals from the Cape Fear River into a regional power plant and in obtaining permission to operate a cluster of groundwater piezometers on property owned by the company.
