Hi my name is Nick Stasulis and I work with the Maine Office of the New England Water Science Center. In this video we will outline the process of editing vertical information using the SonTek RSSL software.

During playback and review of measurements made with RSSL you may find entries that are incorrect and need to be fixed, such as incorrect transducer depth or incorrect screening distance for the M9. Other data quality issues like velocity extrapolation or user input water depth may need adjustment, too.

These issues can be addressed by double clicking on an individual station in the contour plot. A vertical dialog box will appear. Editable boxes in the center of the dialog are Transducer Depth, User Input Water Depth and Screening Distance, as well as the coordinate system. All of these entries can be changed for one station or applied to all stations using the checkbox here. Be aware that the user input depth should likely only apply to that one station.

Evaluation of extrapolation methods is covered in a separate video, but these settings can be changed by selecting the profile extrapolation button here and making edits in the box that appears. Notice you can apply this setting to all stations. Often this is done for the entire measurement and only on a section by section basis if a section is significantly different from the typical profiles of the other sections, so the examination should concentrate on the main part of the channel where the majority of discharge is.

The velocity correction factor should not need edits routinely, and the gage height information can be edited as well.

In the system page, there are several other fields in the system settings than be edited as needed, but understand they apply to the entire measurement.
