dc.descriptionAbstract: The fluid shear stress applied to the underside of a simulated floating Ice cover was measured in a laboratory flume. The measured values were compared with values of the shear stress computed from the von Karman-Prandtl velocity distribution fitted to the velocity profiles measured beneath the cover. For the lower velocity runs (~0.079 m/s) the measured and computed values of the shear stress were in close agreement. At the high velocity flows (~0.137 m/s) the measured values were roughly one-half those calculated from the velocity distribution. As the underside of the cover became increasingly rougher, the position of maximum velocity moved closer to the bottom of the channel. It was shown that the Darcy friction coefficient is exponentially related to a normalized ice cover thickness, which suggests that it is a measure of the roughness of a fragmented ice cover.-
