Stationary Measurement data collection is the process of making individual velocity profile measurements at fixed locations across the width of a stream, river, or canal using the S5/M9 and then computing the resulting discharge. The key difference when using RiverSurveyor Stationary Live (RSSL) with the S5/M9 is that the entire water column is profiled at once instead of measuring at fixed depths. The program is freeware for data viewing , for data collecting the price must be discussed with the authors.
