Hydrodynamic modeling is a scientific method used to simulate the movement of water in various environments, such as rivers, lakes, and oceans. This modeling helps researchers understand how water flows, how it interacts with the surrounding landscape, and how it can be affected by factors like rainfall, tides, and human activities. These models use mathematical equations to represent the physical laws governing fluid motion. By inputting data about water depth, velocity, and other variables, scientists can predict changes in water behavior, which is essential for managing resources, predicting floods, and studying ecosystems like wetlands and estuaries.
