Using Muskat's and Ward's general form of Forchheimer equations, we describe the fluid dynamics by a nonlinear degenerate parabolic equation for the density. We study Galerkin finite elements method for the initial boundary value problem. The existence and uniqueness of the approximation are proved. The prior estimates for the solutions in $L^\\infty(0,T;L^q(\\Omega)), q\\ge 2$, time derivative in $L^\\infty(0,T;L^2(\\Omega))$ and gradient in $L^\\infty(0,T;W^{1,2-a}(\\Omega)),$ with $a\\in (0,1)$ are established.
