Groundwater Overlay
The groundwater overlay is an implementation of the Water model optimized for calculating the flow of underground watertables. This implementation focuses on water flowing at a low speed, and on the functioning of the water system without calamitous events such as breaches.
Use cases
The groundwater overlay can be used and is recommended when exploring the following use-cases:
- Modeling a static, low-speed water system
- Modeling the long-term effects of excessive rain or excessive drought on the water table
- Modeling the spread of chemicals through the underground, carried along by water
Using the overlay
It is important to model a fully functional static water system for any relevant use of the groundwater overlay. After setting up the static water model, additional effects can be modeled to account for special circumstances. This has the added benefit of creating a control-state, to which results of calamities can be compared.
Geo data
The following data needs to be prepared, so that it can be loaded in and used by the water model's calculations: Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist Template:OverlayChecklist
Environmental effects
Consider the duration you want your simulation to last, and whether you wish to account for rainfall in your model. The following environmental data needs to be prepared, so that it can be configured and used by the water model's calculations:
