17. Edges

The Edges button opens a window that allows the user to review and change settings associated with the discharge computations. This window has a table containing the edge setting and graphs to evaluate The Edges window displays a table that lists the edge settings and graphs that show the data used to compute the left and right edge discharges. Edge settings can be edited by clicking the appropriate row and column in the table.

Summary Table

1. Summary Table
The Summary Table shows the edge settings and resulting discharge. Edge settings can be changed by clicking the appropriate column in the table. For details on editng the edge setting see Edit Edges.
 
Filename—Filename of transect.
Start Edge—Specifies at what edge the transect was started (Left or Right).
Left Type—Specifies the type of edge for the left bank.
Triangular—Sets the left coefficient to 0.3535.
Rectangular—For TRDI and QRev processing (WR2 and RSL data), sets the left coefficient to 0.91. For SonTek processing, an equation is used to set the coefficient (Mueller, in review).
Custom—Allows the user to type a custom coefficient in the Left Coef column.
User Q—Allows the user to not specify a coefficient but rather to specify the discharge in the left edge by entering the discharge in the Left Discharge column.
Left Coef—Coefficient, C, in the equation () for computing the left edge discharge.
Left Distance—The user measured distance (L) from the end of the transect to the water’s edge on the left bank.
Left # Ens—The number of ensembles specified to determine the water velocity (V) and depth (D) for the edge discharge equation.
Left # Valid—The number of left edge ensembles that contain valid data that is used to determine the water velocity (V) and depth (D) for the edge discharge equation.
Left Discharge—The discharge computed or entered (User Q) for the left unmeasured edge.
%—Percent of total discharge in the left edge.
Right Type—Specifies the type of edge for the right bank.
Triangular—Sets the right coefficient to 0.3535.
Rectangular—For TRDI and QRev processing (WR2 and RSL data), sets the right coefficient to 0.91. For SonTek processing, an equation is used to set the coefficient (Mueller, in review).
Custom—Allows the user to type a custom coefficient in the Right Coef column.
User Q—Allows the user to not specify a coefficient but rather to specify the discharge in the right edge by entering the discharge in the Right Discharge column.
Right Coef—Coefficient, C, in the equation () for computing the right edge discharge.
Right Distance—The user measured distance (L) from the end of the transect to the water’s edge on the right bank.
Right # Ens—The number of ensembles specified to determine the water velocity (V) and depth (D) for the edge discharge equation.
Right # Valid—The number of right edge ensembles that contain valid data that is actually used to determine the water velocity (V) and depth (D) for the edge discharge equation..
Right Discharge—The discharge computed or entered (User Q) for the right unmeasured edge.
%—Percent of total discharge in the right edge.

Edges Graphs

3. Edges Graphs
The data used in the computation of the left and right edge discharges are displayed in the Left Edge and Right Edge panels. The transect data displayed are selected by clicking on the filename in the table. The filename of the transect being displayed is below the table and just above the left and right edge panels. Each edge panel contains a color contour graph of the water speed and a ship track graph. These graphs only contain data from the edge ensembles. The color contour graph should be used to evaluate the consistency of the depth and water speed. The ship track graph should be used to evaluate boat movement during the collection of the edge ensembles. The black square also indicates the end of the transect closest to shore. The blue arrows represent the depth averaged velocity vectors.
