To track water in a hydrological system, i.e. find where water from a specific point flows to, it is possible to artificially add a chemical emitter in the water system. Any water passing through that building will pick up the chemical. By having a result type added which highlights that chemical, the flow of the water can be tracked quite accurately.
For the purposes of this scenario, a simple hydrological model will be assumed, although the same technique can be used for breaches and other calamitous scenarios. We will also assume we can use the TRACER_A particle as our "tracker". We will track any water flowing through a specific location.
If TRACER_A is already in use for another purpose, any other tracer can be used. At least one tracer should be unused in order to fulfill this use-case. The instructions on this page will assume TRACER_A.
Requirements
Before implementing this use-case, make sure you have a basic water model set up. For the specified scenario, the ground overlay is recommended, though any variant will work.
Also ensure the following in your project, if possible:
- The hydrological system has some input which allows or causes water flow. An inlet, a pump, or even an incline would be sufficient.
- The hydrological system has a TRACER_A result type, either as main result or as a child result type.
- The simulation is set up to output a reasonable amount of timeframes. For most simulation durations, 25 to 50 timeframes will suffice.
Steps
The use-case can be implemented through the following steps.
- Configure a base hydrological system.
- Find the location, from where you wish to track the water, using the 3D Visualization.
- Add an above-ground building to that location. A building with the function "reeds" often works best, as it can be placed both on land and in water.
- Add the "TRACER_A" attribute to the added building, with a value of "1". See How to add and remove an Attribute
- Ensure the overlay is recalculated.
- Inspect the "Tracer A" result overlay. The greater the concentration of the tracer in any given location, the more water from the inlet has flowed there.
- Select the "play" option in the overlay's legend. The animation will show the flow of the water from the indicated location.
Notes
- To track water from different locations or sources (inlets, or other buildings), add the chemical attribute to the building of which you wish to track the water.
- To track water from different sources collectively, each source can be configured with the same chemical attribute. (In the specified example, multiple sources can be provided with the TRACER_A attribute.)
- To track water from different sources with the ability to differentiate between what water came from which specific source, each source can be given a different tracer to produce.
