The system of equations of one-dimensional shallow water over uneven bottomin Euler's and Lagrange's variables is considered. Intermediate system ofequations is introduced. Hydrodynamic conservation laws of intermediate systemof equations is used to find all first order conservation laws of shallow waterequations in Lagrange's variable for all bottom profiles. The obtainedconservation laws are compared with the hydrodynamic conservation laws of thesystem of equations of one-dimensional shallow water over uneven bottom inEuler's variables. Bottom profiles are given for which there are additionalconservation laws.
