Abstract: | The solvability of the problem of the flows resulting from the incidence of a discontinuous wave on a bottom step is studied
using a single-layer shallow water model. Solutions in which the total energy of the flow is conserved at the step and those
in which it is lost at the step are considered. Regions of double and triple hystereses in the obtained self-similar solutions
are found. An analogy is drawn with the problem of single-layer flow over a bottom obstacle.
