“Developing countries have few resources for ground-based hydrological investigations to determine optimal placement of boreholes for community water access. Remote sensing data are available at a variety of resolutions and sense different parameters, and are useful inputs for hydrologic models, but these data are rarely obtainable in developing countries with the parameters or resolutions necessary for hydrologic applications. This research seeks to use and improve existing remote sensing and GIS techniques to identify areas of optimal water supply in locations with limited geologic or hydrologic information, such as Gulu District, Uganda. Fusing different remotely sensed data sets can produce higher resolution data sets of some necessary parameters. This research focuses on fusing remotely sensed data sets to aid in the investigation of groundwater resources using a multicriteria decision method. This research was conducted in three phases. The first phase was a proof-of-concept study that fused Sentinel-1 synthetic aperture radar (SAR) data with unmanned aerial vehicle (UAV) acquired photogrammetry using Principal Component Analysis (PCA) to improve the accuracy and resolution of digital elevation models (DEMs) and enhance surface lineaments. This fusion technique was then applied in the second phase to Alos Palsar quad-pol SAR and magnetic data acquired in the Gulu District of Uganda. The final phase of research used the lineament map produced in the second phase as one of the datasets for a final groundwater potentiality model. The data for this particular model can be processed and a groundwater potentiality model developed in a short time span to benefit crisis and disaster affected communities in a more immediate manner”--Abstract, page iv.
