Results (Water Overlay)

When a simulation for a particular Water Overlay is completed, the results of the calculation as well as large amounts of additional information and visualizations are made available for analysis.

Grid Overlay results

Main article: Result type (Water Overlay)

Depending on the configured result type, various results are stored as numerical values in a grid spanning the project area. The stored values and their context depend on the selected result type. These grid results are not only stored for the Water Overlay, but also for its related Result Child Overlays. Additionally, apart from the end result, multiple intermediate timeframes may be generated and stored for each result child overlay.

Object output

Several result parameters in formulas used for hydraulic structures or hydrological features are recorded in an Attribute for that Item, as an Attribute array with one value per timeframe. This is to facilitate in-depth analysis of throughput and functioning of many geographical features in the Water Overlay. The following are supported:

• Object flow output. Water flowing through a hydraulic structure or hydrological feature.
• Object height output. The (changing) datum height of the hydraulic structure or hydrological feature.
• Object datum output a. The (changing) water level datum of the hydraulic structure or hydrological feature at interaction side a.
• Object datum output b. The (changing) water level datum of the hydraulic structure or hydrological feature at interaction side b.

Water balance

Main article: Water balance (Water Overlay)

For a quick overview of where water in the model came from and where it has ended up, the water balance can be inspected. This is intended for verification that across the entirety of the model, all water is accounted for and there are no unexpected points where water comes from or ends up.

System visualization

Main article: System visualization (Water Overlay)

Because the water system is composed of many hydrological features which move water around, insight into how the model facilitates water flow is necessary to understand how the initial circumstances lead the the outcome they do. The system visualization shows the various connections between locations in the model, and the locations of boundary conditions. Both a low level and a high level visualization is supported.

Weather visualization

Main article: Weather visualization (Water Overlay)

Based on the results computed by the Water Overlay, a visually engaging effect can be shown in the 3D visualization where water appears on and flows across the surface.

Debug information

Main article: Debug info (Water Overlay)

For the purposes of debugging the simulation, and getting a quick insight into some of the numbers relevant to the simulation as a whole. This is mostly for determining whether the simulation has been configured well enough to provide a realistic model.
