The Rainfall 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 Rainfall overlay specializes in displaying the hazard and impact of (heavy) rainfall over the project area. Based on the elevation model, terrain roughness and representations of the sewer and water systems, several result types can be generated by the accompanying Water Module.
A Rainfall Overlay Tutorial is available to get you started with this overlay.
In order to get more familiar with the different components of the Rainfall Overlay check out Quadrant 2 of the Water Module Testbed. This Testbed is available to you as a project in the Tygron Platform.
Rainfall overlay results
The Rainfall 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 Rainfall Overlay Wizard. When a simulation finishes, the module stores the result in the Rainfall overlay based on the selected result type. Only one result type can be stored per Rainfall 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 Rainfall overlay. These are known as child overlays. Again, each child overlay only stores one particular result type.
Apart from multiple result types, the Rainfall 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 Rainfall overlay results.
