Abstract

This data set contains the data used in the manuscript "Experimentally mapping water surface elevation, velocity and pressure fields of an open channel flow around a stalk" by Moreto, Reeder, Budwig, Tonina and Xiaofeng. The manuscript report the results of an experimental investigation of the time-averaged velocity and three-dimensional pressure fields, quantified in a set of laboratory experiments using stereo particle image velocimetry (SPIV) coupled with a refractive index-matched fluid, for an open channel flow around a barely submerged vertical cylinder as a model for a plant stalk over a plane bed of coarse granular sediment. Full velocity and pressure fields were generated around the cylinder and directly adjacent to the stream bed. The pressure field was calculated using the Rotating Parallel Ray Omni-Directional integration method to integrate the pressure gradient terms obtained by the balance of all the Reynolds-Averaged Navier-Stokes equation terms, which were evaluated with the SPIV measured velocity data at multiple closely-spaced parallel and aligned planes. The detailed mapping of the pressure field allows us to derive the water surface profile that was deformed by the submerged cylinder. This is the first time that such velocity and pressure fields and reconstructed water surface elevations are characterized experimentally for a three-dimensional free surface flow with irregular floor contour in a full-scale flume experiment.
