摘要：
The unique solvability of an analog of the first initial boundary value problem for the quasihydrodynamics equations in the shallow water approximation is established under certain conditions on the data. A solution is regular , i.e., all generalized derivatives occurring in the equation are summable to some power. The proof relies on a priori estimates and the contraction mapping principle.
