Water Balance Equation Numerical : Engineering Hydrology
Jun 17, 2024 · It is also called the continuity equation or conservation equation. In other words, it is the balance of the input and output of water within a given area taking into account net changes in storage.
A system could be a lake or reservoir, or a catchment, an agricultural field, or even a suburb in a city. In fact, we can do a water balance at the global scale. The approach can be expanded to undertake …
