ADV channel hydrodynamics data set for six engineered logjam structures

Using small-scale laboratory experiments, the upstream and downstream hydrodynamics of six idealised engineered logjams were investigated using Acoustic Doppler Velocimetry. Velocity profiles were measured along the channel centreline upstream and downstream of these jams. Velocity records were decomposed into time-averaged and fluctuation components, allowing the analysis of first and second order turbulence statistics at each measurement location and for each logjam. The data set comprises six excel files, with a separate file for each jam: S1 (non-porous jam), S2 (long, porous jam), S3 (long, open-porous jam), S4 (staggered jam), S5 (short, porous jam) and S6 (scaled, short, porous jam). The data for each measurement location is included in a separate worksheet, with streamwise distance expressed in vertical gap width (b₀).
