The objective of the present study is to investigate performances of the first, the second and the third order accurate methods for the calculation of inviscid fluxes in the shallow water equations. For this purpose, Roe's flux difference splitting method with MUSCL interpolation scheme is applied to solve the two dimensional shallow water equations. In the above mentioned methods, minmod slope-limiter is applied. A partial dam-break problem and circular dam-break problem are analyzed in order to compare the performance among the presented schemes. The results indicate that differences between the first-order upwind scheme and higher order ones are clear while those between the second and the third are slight.
