Infiltration Grid Properties

The Infiltration Grid Properties dialog box allows the user to define various infiltration grids and their properties, style the border associated with the infiltration grid polygon, change the image’s transparency, and display the infiltration grid legends in the Map Data Layers panel and/or on the Map View.

Follow the steps given below to open the Infiltration Grid Properties dialog box:

  1. Click on the […] button next to the Infiltration grid name in the Map Data Layers panel.
    […] button next to Infiltration grid name in the Map Data Layers panel.Note that the Infiltration grid name is generated under the Map Data Layers panel after computing the infiltration using the Compute Infiltration command. To learn about the Compute Infiltration command, refer to this article in our knowledge base.
  2. The Infiltration Grid Properties dialog box will be displayed.

The Infiltration Grid Properties dialog box contains three tabs as described below:

  • General Options
  • Loss Parameters
  • Spatial Reference

General Options

Various sections of the General Options tab are described below:

  • General Information
    This section contains read-only information about the location of the infiltration grid file, the cell dimensions, the cell count, and the grid dimensions.
  • Default Elevation Grid Stylization
    This section defines the elevation grid stylization. It allows the user to set border color, border size as well as display an infiltration grid legend in the Map Data Layers panel and/or on the Map View after running the Compute Infiltration command. To learn about the Compute Infiltration command, refer to this article in our knowledge base.
  • Fill Transparency
    This section is used to change the transparency of the image so that the user can see through the image to the background Base Map. A transparency value of 40 to 50% works well.

Loss Parameters

The Loss Parameters tab consists of the Infiltration Layer Definition table. In this table, the software automatically defines a one-to-one mapping of infiltration parameters such as Land Type, Curve Number, Initial abstraction, and Minimum Infiltration Rate. The user can also edit the infiltration parameters from the table.
Loss Parameters tabbed panel

Clicking on the […] button in the Min Infiltration Rate(in/hr) column will display the Typical Exfiltration Rates lookup table dialog box, which shows the typical infiltration rates.

To learn more about the infiltration methods and associated parameters, refer to this article in our knowledge base.

Note that the Loss Parameters tab panel content changes depending upon the infiltration (loss) method (Deficit Constant, SCS Curve Number, or Green and Ampt) used for computations in the Select Infiltration Method of the Compute Infiltration command. To learn about the Compute Infiltration command, refer to this article in our knowledge base.

Spatial Reference

The Spatial Reference tab allows the user to view the details of the project’s CRS. Refer to this article in our knowledge base to learn more about spatial reference.
