Subbasin Table Edit Command

The Subbasin Table Edit command allows the user to edit the subbasin parameters in one dialog box for common hydrology infiltration and runoff methods. When the user selects this command, a modeless dialog box will be displayed. This dialog box contains an editable data grid listing all the subbasins in the current scenario. When the user selects a row in the data grid, the corresponding subbasin will be zoomed to the Map View (if not visible) and highlighted. In addition, the user can select a subbasin from the Map View, and the corresponding row in the data grid will be shown selected.

Follow the steps below to use the Subbasin Table Edit command:

1. From the Input ribbon menu, click the Drainage Subbasins dropdown menu and then select the Subbasin Table Edit command.
   
2. The Subbasin Table Edit dialog box will be displayed.
   

The following sections describe how to use the Subbasin Table Edit command and interact with the above dialog box.

Subbasin Parameters

The Subbasin Parameters section will display the editable data grid columns listing the subbasin parameters contained in the current scenario. Based upon the selected hydrology infiltration and runoff methods in the Project Options backstage page, as shown below, the data grid columns listing will be changed.

In general terms, the following column sections will be listed in the data grid:

Note that only the hydrology infiltration and runoff methods selected in the Project Options backstage page will be listed in the data grid if they correspond to the common hydrology infiltration and runoff methods listed below.

Infiltration Methods

The user can select the following infiltration methods from the Project Options backstage page and the associated parameters will be listed in the data grid of the Subbasin Table Edit command:

Method Name	Data Grid Column Name
SCS Curve Number	Initial Abstraction [inches/mm] Curve Number Impervious Surface [%]
Green & Ampt	Initial Content Saturated Content Initial Deficit Suction [inches/mm] Hydraulic Conductivity [(in/hr) (mm/hr)] Impervious Surface [%]
Initial & Constant	Initial Loss [inches/mm] Constant Rate [(in/hr) (mm/hr)] Impervious Surface [%]

Runoff Methods

The user can select the following runoff methods from the Project Options backstage page and the associated parameters will be listed in the data grid of the Subbasin Table Edit command:

Method Name	Data Grid Column Name
SCS Unit Hydrograph	Lag Time [Minutes]
Clark Unit Hydrograph	Time of Concentration [minutes] Storage Coefficient
Snyder Unit Hydrograph	Lag Time [minutes] Peaking Coefficient

Exporting Data to Excel or PDF

The user can export the data grid column values to Microsoft Excel or PDF documents. To export data into Excel or PDF, right-click in the data grid column and select Export Table to Excel or Export Table to PDF command from the displayed context menu.

Sending Data to the Windows Clipboard

The user can send the data grid column values to the Windows clipboard. Moving a data grid column value to the clipboard allows those values to be pasted into another software application. To transfer the data to the Windows clipboard, right-click in the data grid column and select the Copy Table to Clipboard command from the displayed context menu. The data will automatically be sent to the Windows clipboard.

After editing the desired subbasin parameters for common hydrology infiltration and runoff methods, the user can click the [Close] button to close the dialog box.
