Basic water model use case (Water Overlay)

For all effective uses of any variant of the water overlay, it is strongly recommended to load in data for a stationary water system. The behavior of any water, whether it's pre-existing, expected inflow, or due to natural event or calamity, is affected by the presence of features which can capture or steer water in other directions. The more real-world hydrological features and hydrological constructions are loaded in, the more accurately the water flow can be simulated.
