%X This data set was completed in the bend flume of the State Key Laboratory of hydraulic engineering simulation and safety, Tianjin University. The experiment aims to explore the mechanism of dike collapse by measuring and analyzing the change law of hydraulic factors in the breach shape and breach area during the collapse of cohesive soil dike under freeze-thaw conditions. The data set includes the transverse width and vertical depth of the breach, the water levels in front of the dike, behind the dike and in the Bacher trough, the flow at the Bacher trough, and the flow velocity at the measuring points, including the diversion velocity in the X, y and Z directions.
