Abstract
Velocity distribution over pronounced rough surfaces shows a deviation from  log- law for small values of y. In the case of duned bed, this distance may be 0.5  to 2 times the dune height. The concept of additional mixing length was used to  obtain a log- law which shows deviation in velocity from log- law near the bed  and constants appearing in the equation were evaluated using experimental  data from flume studies.
