Data for: Experiment on hydrodynamic characteristics of plunging flows in bedrock canyon bends

The dataset is about the hydrodynamic characteristics of plunging flows in bedrock bends. The dataset includes raw data of bed topography of the Ciping Reservoir canyon section of Jinghe River and the bed of the flume experiments, flow field along the center profiles of plain- and undulating-beds conditions, and the bed shear stress of plain- and undulating-beds conditions.,
The bed topography measured at the Ciping Reservoir canyon section of Jinghe River, China, measured by actual survey and aerial survey by UAV.
The bed of flume experiments measured by laser in undulating-bed conditions.
The flow field measured by ADV.

A generalized physical model was built to investigate the hydrodynamic characteristics of the plunging flows in a constant curvature flume with flat and undulating beds, respectively. We first measured the topography of canyon section located near the Ciping Reservoir of Jinghe River, and scaled the bed topography to flume. The flow field including time-averaged velocity, depth-averaged velocity, and turbulence characteristics measured by ADV (Acoustic Doppler Velocimeter). The characteristics of plunging flows could obtain from flow field such as the relative of plunging flows (*umax/umin*) and the strength of velocity inversion (*ηmax*).
