Rain Garden

Action Type: Draw Polygon on Terrain (not allowed on scenarios with start time > 0)

Purpose and Effect: This action is part of the nature-based solutions action set. It allows users to create a zone with enhanced infiltration properties. It may feature a designated storage and a constant loss rate. Rain gardens are typically filled with aggregate or other porous materials to promote infiltration.

The primary difference from the generic nature-based solutions is that the default parameters are configured to reflect the infiltration properties commonly found in materials used for rain gardens.

To study the effects of rain gardens, users can switch between various visualizations in the Visualization Settings Panel, under the Layers: Visualization category. Begin by activating the terrain overlay and then color the terrain based on a soil property. Options include Infiltrated Height, Stored height, Lost Height, and others.

Additionally, users can also display information as labels through the action tool panel. For a more detailed analysis, label plots are also accessible through the action tool panel. Keep in mind that the \(x\)-axis always shows the entire scenario duration. To complete the plot, simulate until the scenario concludes.
