Voltage signals of several Acoustic Displacement Meters recorded at the stepped spillway of The University of Queensland

Recordings sampled at the stepped spillway of Prof. Chanson at The University of Queensland during a research stay in 2017. Flow depths measured all through the non-aerated region. The data shows growing free surface fluctuations with increasing streamwise coordinate, up to the inception of self-aeration. Data analyzed in Chapter 10 of: Valero, D. (2018). On the Fluid Mechanics of Self-Aeration in Open Channel Flows. PhD thesis, Université de Liège. Spillway geometry introduced in the work of: Zhang, G., Chanson, H. (2016). Hydraulics of the Developing Flow Region of Stepped Spillways. I: Physical Modeling and Boundary Layer Development. Journal of Hydraulic Engineering, 142(7), 04016015. The presented results were obtained in the framework of a project-related personal exchange program funded by the German Academic Exchange Service (DAAD) and Australia-Germany Joint Research Cooperation scheme with financial support of the Federal Ministry of Education and Research (BMBF).
