Sentences with phrase «hydrologic model»
A hydrologic model is a computer-based tool that helps scientists and engineers understand and predict how water moves and behaves in a specific area, such as a river basin or watershed. It takes into account factors like rainfall, evaporation, soil characteristics, and topography to simulate and study the flow of water through the landscape. This information can be used to make informed decisions about water management, flood forecasting, and understanding the impact of human activities on water resources. Full definition
