The general method of constructing high-resolution schemes to solve 2D shallow water equations is studied. Using the technique of group velocity control
some high-resolution schemes are obtained
such as three-order upwind group velocity control schemes and four-order group velocity control schemes. Using the dispersion and anisotropy measurement
a criterion to evaluate approximation degree of difference operators to differential operators is obtained.
