| The summary table is a new tool to allow the user to view calculations along cross-section arcs in their project. To use the summary table, you must have a cross section coverage, centerline coverage, and geometry (i.e. grid, mesh, scatter). To access the summary table, right-click on the 1D-Hydraulic Cross-Section coverage and select '''Summary Table...'''.

| ==Summary Table Options==
| |
| The ''Summary Table Options'' dialog is where the user will specify which calculations are desired, as well as which geometry to use, and which portions of the cross section should be used.
| |
| | |
| ===Data Source===
| |
| | |
| The data source button is used to select the geometry that has the datasets for the calculations.
| |
| | |
| ===Cross section options===
| |
| There are three options for the cross sections: Full cross-section, Main channel only, and Overbanks and main channel.
| |
| *''Full cross section'' – This option is used when there is no cross-section database, overbanks have not been specified, or if the calculations should be done over the entire cross-section.
| |
| *''Main channel only'' – This option can only be used if there is a cross-section database. The calculations will be performed only on the main channel portion of the cross section , defined as the space between the right and left overbanks.
| |
| *''Overbanks and main channel'' – This option can only be used if there is a cross-section database. The calculations will be performed on three separate portions of the cross section: the left overbank, main channel, and right overbank.
| |
| | |
| ===Datasets===
| |
| After selecting a data source, the spreadsheet will be populated with all of the scalar datasets that belong to the data source. For each dataset, the user can toggle on minimum, average, and maximum to be calculated, as well as select the dataset timestep to be used. To calculated the minimum, maximum, and average values for each cross-section, SMS will interpolate the values from the dataset to the points along the cross-section. These interpolated values will then be used to determine the minimum, maximum, and average value.
| |
| | |
| ===Defaults===
| |
| The '''Select defaults''' button will search for common dataset keywords in the list and automatically turn on the average calculation. The keywords are: "water_elev", "wse", "vel_mag", "vmag", and "froude".
| |
| | |
| ===Advanced Calculations===
| |
| Some other helpful calculations are available in the "Advanced Calculations" section.
| |
| *''Flow'' – To calculate the flow over the cross sections, it is necessary to specify a velocity dataset (vector) and a depth dataset (scalar). SMS will then calculate the flow over the cross-section at the specified timestep.
| |
| *''Width'' – To calculate the width of the cross sections, it is necessary to specify an elevation dataset and a water surface elevation dataset. SMS then compares the water surface elevation with the cross-section elevation to determine the width.
| |
| | |
| ==Summary Table==
| |
| Once all of the options are set, click on '''Generate table...''' to have SMS compute the desired values and display them in a table.
