Based on the reconstruction of interface variables with the fifth-order WENO, a high resolution scheme is proposed and the performance of capturing dam break waves is analyzed. With the part is linearized through Roe average, one dimensional shallow water equation is directly and decoupled solved, the velocity distribution and depth distribution are obtained. Numerical simulation shows that the decoupled schemes with WENO5 reconstruction has higher resolution and it shows the movement of dam-break.
