Abstract: | The long-wave equations describing three-dimensional shear wave motion of a free-surface ideal fluid are rearranged to a special
form and used to describe discontinuous solutions. Relations at the discontinuity front are derived, and stability conditions
for the discontinuity are formulated. The problem of determining the flow parameters behind the discontinuity front from known
parameters before the front and specified velocity of motion of the front are investigated.
