ASCE has honored the writing team of Daniel Valero and Daniel Bung with the 2020 Karl Emil Hilgard Hydraulic Prize for the paper “Vectrino Profiler Spatial Filtering for Shear Flows Based on the Mean Velocity Gradient Equation,” published in the July 2018 issue of Journal of Hydraulic Engineering.
In this article, the authors provide a new method to filter ADV Vectrino profiler velocity estimations in order to improve the predictions of the lowest-performing bins. The method is based on the differential equation for the mean velocity gradient, which represents a flexible differential approach for the description of the most common flows generally studied. The method can be applied to shear flows, as shown in this study, resulting in the rejection of velocity data presenting gradients that are not physically consistent.
The Karl Emil Hilgard Hydraulic Prize is presented to the author or authors of the paper that is judged to be of superior merit in dealing with a problem of flowing water, either in theory or in practice.
