could promote the accuracy of the scheme up to about two times higher, but the cost of computing will increase more than the JS 7th order one. So, we conclude that employing 7th order of JS-WENO leads to higher accuracy with less computational costs....

membership function is introduced. The proposed method is able to provide a continuous estimate of the head along horizontal axis with high accuracy, low computational cost while avoiding from getting involved into complex mathematical equations. Experiments...
