Bed shear stress measurements in rough beds flows through sparse array of rigid emergent vegetation

This dataset provides the hydraulic boundary conditions, bed shear stress measurements, and double-averaged velocity measurements collected in flume experiments presented in the article "Bed shear stress model for rough bed flows through rigid emergent vegetation" (Aliaga & Aberle, 2025). This research characterizes bed shear stress and double-averaged flow characteristics in rough-bed flows covered with sparse arrays of rigid emergent cylinders. For this purpose, a novel adaptation of a shear plate was used to directly measure the bed shear stress acting at the canopy scale. These bed shear stress measurements were analyzed in relation to spatially averaged near-bed flow quantities for two array densities and a reference scenario without cylinders. The primary outcome of this research is the formulation of a bed shear stress model for rough-bed flows covered with rigid emergent vegetation.
