Channel hydrology, hydraulics, and sediment composition are key variables to calculate vertical and horizontal channel movement. There are a variety of published methods available for estimating channel bed scour that were highlighted in the PRCI Phase A1 report. This report seeks to further the understanding of these methods by comparing computed scour derived from the published methods to actual measured observations in the field. Depth measurements were collected across a transect(s) at six study locations during a variety of flows over the 19-month study period (March 2020 through September...
