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 [[Water model#Breach|breaches]].
The Groundwater overlay calculates and visualizes the movement of water underground and the resulting [[Ground watertable result type (Water Overlay)|watertable]].

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

It is important to model a fully functional static water system for any relevant use of the groundwater overlay.

Groundwater overlay

The Groundwater Overlay is a variant of the Water Overlay, which in turn is a grid overlay. Water overlays are connected to the Water Module, a complex hydrological calculation module within the Tygron Platform.

The Groundwater overlay calculates and visualizes the movement of water underground and the resulting watertable.

In order to get more familiar with the different components of the Groundwater Overlay check out Quadrant 4 of the Water Module Testbed. This Testbed is available to you as a project in the Tygron Platform.

Groundwater overlay results

The Groundwater Overlay is a Water Overlay that is connected to the Water Module. This Water Module performs two dimensional grid based water simulations for a large set of input data and parameters, configured mostly through a related Water Overlay Wizard. When a simulation finishes, the module stores the result in the Groundwater overlay based on the selected result type. Only one result type can be stored per Groundwater overlay.

The Water Module however, is not restricted to generating only one type of result. Instead it can produce multiple unique result types for one single simulation. Fortunately it is possible to add additional result type overlays which relate to a particular Groundwater overlay. These are known as Result Child Overlays. Again, each child overlay only stores one particular result type.

Apart from multiple result types, the Groundwater overlay can also store result data of multiple, intermediate simulation results, instead of just a single end result. These intermediate simulation results are known as timeframes.

For the full list of result types, see List of Result Types.

For other results, which are not overlay results, but still related to the simulation for a particular Rainfall overlay, see Groundwater overlay results.

Improvements year round groundwater calculations.
