| 520 | |a"Full scale and model tests were conducted on interlocking concrete blocks which are placed in a matrix as erosion protection in urban drainage channels. It was determined that Manning's roughness coefficient "n" from scaled up model data is about 15% lower than values obtained from prototype tests. The results suggest that great care must be used when using values of Manning's "n" obtained from model tests"--Summary. |
