For water management purposes it can be relevant to know how water will stabilize throughout the system. This can be in a default situation, where there is a nominal amount of water in- and outflow. This can also be in a situation where the system is under duress, such as with a consistent amount of rainfall. There are multiple possible definitions of a stable water system, but a common characteristic is that the inflow and outflow match up, leading to either a consistent amount of water in the system or a predictable water rise/fall at points of measurement.
For the purposes of this scenario, a simple hydrological model will be assumed, with an inflow of water from an upstream source and a downstream means for water to leave the water system.
- Configure a base hydrological system. For the specified scenario, the rainfall overlay is recommended.
- Ensure the simulation is set up to output a reasonable amount of timeframes. For a stabilization case, one timeframe per 12 hours of simulation time is reasonable.
- Also ensure the hydrological system has appropriate inflows and outflows for the hydrological system.
- Also ensure the hydrological system has a SURFACE_LAST_VALUE result type, either as main result or as a child result type.
- Ensure the overlay is (re)calculated.
- Inspect the "Surface last value" result overlay.
- In the location where water should stabilize, place a point measurement using the measurement tool. The graph will demonstrate whether the water stabilizes, and if so at what level.
