Critical Storm Summary Results Table

Once the critical storm analysis is complete, this table displays the results of the analysis.

On the right-click context menu of any column, you can use "Dendritic Sort (Upstream -> Downstream)". This is the same sort option found in FlexTables.

	Export	Exports the contents of the table to tab or comma-delimited text files.
	Copy	This button will copy the current selection in the table. The drop-down also provides the option to copy the column headers. You can also right-click in the table to get the same copy options or use CTRL-C to copy the contents of the selection (this excludes the headers).
	Edit	This will open the table editor to select or deselect columns to show in the table.
	Zoom	This will zoom to the node in the selected row. If multiple rows are selected, the last row selected will be used for the zoom.
	Find	Use this button to find any text in the table.
	Report	The button generates a report for the table. The drop-down menu contains "Report Current Time Step" and "Report in XML". The "Report in XML" will generate an XML Report that can be modified by applying a different XML Template.
	Options	This button provides options to create a selection set, add to a selection set and remove from a section set. You can also access the critical storm status options from the drop-down menu.
	Select In Drawing	This button provides a drop-down with the following options: Select in Drawing - selects the nodes selected in the table in the drawing, clearing the existing selection. Add to Selection - adds to the current drawing selection, the currently selected nodes in the table. Remove from Current Selection - removes from the current selection, the currently selected nodes in the table. Select within Current Selection - selects within the current selection the selected nodes in the table removing all other elements from the selection. Select from Drawing - selects the nodes in the current drawing selection in the table. If the node is not in the table, it is not selected. Other element types are ignored completely.

There are twenty-two (22) available columns in the table. By default, all columns are available in the table. You can modify which columns are included by using the Edit button in the toolbar. The available columns are as follows:

* - this column shows the color selected for the status of the node.
Status - either OK, Surcharged, Overflow Risk, or Overflow. See the Critical Storm Analysis section to see how each status is determined.
Node - this is the label of the node analyzed.
Element Type - the type of node - i.e. Manhole, Catch Basin, etc.
Downstream Pipe - this is the label of the downstream pipe connected to the node.
Critical Scenario - this is the label of the critical scenario for this node.
Critical Storm Event - this is the storm event assigned to the scenario in the rainfall runoff alternative.
Soffit (Pipe) - this is the soffit of the downstream pipe.
Elevation (Rim) - this is the rim elevation of the node.
Freeboard (Required) - the required depth below the rim elevation that is used to determine the lower limit of the overflow risk status.
Freeboard Elevation - this is the rim elevation of the node minus the freeboard depth.
Freeboard Height (Minimum) - this is minimum distance of the Hydraulic Grade (Maximum) below the Elevation (Rim) for the critical scenario. This value will be negative if the element is flooded.
Hydraulic Grade (Maximum) - this is the maximum hydraulic grade of the node for the critical scenario.
Depth (Surcharge) - this is the derived surcharge depth of the node for the critical scenario. The surcharge depth is the difference between the maximum hydraulic grade and the pipe soffit.
First Surcharge (Return Period/Duration/ Rainfall Curve) - this is the label of the first scenario that surcharged for this node. The format is return period/duration/profile.
- To calculate this, the results for the scenarios are inspected, starting with the shortest duration for the smallest return period, and increasing to the longest duration for that return period, then proceeding to the next smallest return period and the shortest duration for it, and so on, until the first scenario that causes surcharging is found.
- The return period and duration are retrieved from the scenario's storm event.
- The rainfall curve is the label of the dimensionless curve used to generate the storm event, if available. If this is not available, it is shown as <unavailable>.
Flow / Capacity - this is the ratio of the maximum flow in the downstream pipe over the full flow capacity of the downstream pipe.
Flow (Maximum Overflow) - the maximum overflow at the node for the critical scenario.
Volume (Overflow) - the total volume of overflow coming out of the node for the critical scenario.
First Overflow (Return Period/Duration/Rainfall Curve) - this is the label of the first scenario that overflowed for this node. The format is return period/duration/profile.
- To calculate this, the results for the scenarios are inspected, starting with the shortest duration for the smallest return period, and increasing to the longest duration for that return period, then proceeding to the next smallest return period and the shortest duration for it, and so on, until the first scenario that causes overflowing is found.
- The return period and duration are retrieved from the scenario's storm event.
- The rainfall curve is the label of the dimensionless curve used to generate the storm event, if available. If this is not available, it is shown as <unavailable>.
Volume (Pipe, Discharge) - the total pipe volume out of the downstream pipe of the node.
Velocity (Pipe, Maximum) - the maximum velocity of the downstream pipe.
Flow (Pipe, Maximum) - the maximum flow in the downstream pipe.

Once the Critical Storm Table is closed, in order to re-open it, the user must rerun the critical storm analysis.
