WRRS research focuses primarily on complex and interrelated geologic and environmental problems using field-based data, satellite remote sensing techniques, and numerical models. The research weaves four interconnected threads related to water resources: (1) addressing issues pertaining to the sources, distribution, sinks, fluxes, and mechanisms of groundwater recharge on local and regional scales; (2) development and assessment of hydrologic models using both field-based data and cost-effective technologies to quantify, forecast, and better understand water resources; (3) advancing the science of satellite applications in hydrology and geology; (4) evaluating groundwater potentialities using near-surface geophysics, isotope geochemistry, and remote sensing. WRRS research is primarily focused on arid to semi-arid environments or within data-sparse environments (e.g., Egypt, Morocco, Kuwait, Pakistan, Saudi Arabia).
