| Abstract: | The bed roughness using the powerfully computational and plotting ability of MATLAB, illustrates all the progress about programme by using observation data. This program was applied to compute the bed roughness directing to the model test in Water Conservancy Institute in Shenyang Agricultural University. At the same time the sensitivity of bed roughness was calculated due to the coefficient of local head loss with this program and it was found that the coefficient of local head loss has great influence on bed roughness. |

| Keywords: | MATALB bed roughness cubic spline interpolation coefficient of local head loss |
