Working with Rain Gage nodes

A Rain Gage node can be located anywhere on the map - you will specify in your Subcatchment nodes which Rain Gage should be used.

The Rain Gage node Properties Window is shown below.

Click in the Name field, type a new name and press the Enter key on your keyboard to adjust the label provided to your rain gage. This is populated by default based on values set on the Model Defaults window, recall how to edit these defaults from the Urban Networks section.Note that if you change the name of a node, this label will be automatically updated in any connecting links so there is no further work to be done.

The X-coordinate and Y-coordinate are automatically filled based on the node icon location in the map view. Note again, this can be located anywhere on the map - you will specify in your Subcatchment nodes which Rain Gage should be used.

A Description and/or Tag can be optional provided. You may find tags helpful to group components together - this can be a way to categorise specific nodes. To edit these, click in relevant the field, type a new value, and press the Enter key.

The Rainfall format must be provided. Use the dropdown provided to select the type of rainfall data from INTENSITY, VOLUME or CUMULATIVE, and the time interval of this data.

A value can be provided to take Snow Catch into consideration. This factor will be set to 1.0 by default.

A Data Source must be selected from the dropdown and two options are provided for this. The Timeseries option requires a Series Name to be specified in the Timeseries fields below. The field will show with a * initially. You can select a pre-defined series if you have one available, or define a new series.

Defining and editing a time series is performed in the same way to as described in How to define direct inflow, and we refer to user here for further details on this method.

The File options requires additional parameters to be provided in the Data File fields below. We refer the user to the Urban Rain Gage Node section of the technical reference for further details on this method.
