Hydrological modeling is a scientific process that involves the simulation and prediction of water-related processes within a watershed or water system. This includes the study of precipitation, evaporation, runoff, infiltration, and groundwater flow. The goal of hydrological modeling is to better understand and predict the movement and distribution of water within a particular area, which is crucial for water resource management, flood forecasting, land use planning, and environmental conservation. Various techniques, such as statistical models, physical models, and computer simulations, are used in hydrological modeling to simulate the complex interactions between water, soil, vegetation, and climate variables. By accurately representing these processes, hydrological models can provide valuable insights and inform decision-making in a range of fields, from agriculture and urban planning to climate change mitigation and disaster risk reduction.
