Abstract

A common method for estimating mean flow speeds in studies of surface runoff is to time the travel of a dye cloud across a measured flow path. Motion of the dye front reflects the surface flow speed, and a correction must be employed to derive a value for the profile mean speed, which is always lower. The laboratory experiments suggest that the use of dye timing as a method for estimating v be abandoned in favour of precision depth measurements and the use of the relation v = Q/wd, at least within the laminar flow range tested
