Reservoir dam break simulation experiment water tank

The utility model relates to a reservoir dam break simulation experiment water tank which comprises a reservoir, four supporting columns are fixedly installed on the top of the reservoir, an experiment tank is fixedly installed on the tops of the four supporting columns, a cover plate is arranged on the top of the experiment tank, and an adjusting box is fixedly installed on the top of the cover plate. According to the reservoir dam break simulation experiment water tank, by arranging the gradient adjusting assembly and the dam break control structure, when needed, the angles of the first gradient plate and the second gradient plate can be adjusted through the gradient adjusting assembly, and therefore reservoir dam break experiments under different river bed gradients can be carried out; the height of the movable plate in the vertical direction can be adjusted through the motor, the rotating rod and the winding wheel, then the flow of water flowing through the movable plate can be controlled, the influence o
