Geohydrologic
Geohydrologic refers to the study of the interactions between geology and hydrology, focusing on the movement and distribution of groundwater within the Earth's subsurface. This field examines the physical and chemical properties of rocks and soils that affect the flow of water, as well as the factors influencing groundwater recharge, discharge, and contamination. Geohydrologic research plays a crucial role in water resource management, environmental protection, and land-use planning.
