Water isotopes in modern engineering hydrology play a crucial role in understanding the movement, origin, and age of water within hydrological systems. Stable isotopes of hydrogen (²H) and oxygen (¹⁸O), along with radioactive isotopes like tritium (³H), are increasingly used as natural tracers to study precipitation sources, evaporation effects, recharge processes, and interactions between surface water and groundwater. In engineering hydrology, these isotopes support the design and management of water supply systems, flood control, and groundwater sustainability projects by providing precise data on water pathways and residence times. Their application enhances traditional hydrological methods, offering a powerful toolset for addressing complex water resource challenges under changing climatic and anthropogenic pressures.
