摘要：
Assuming time-averaged velocity as a random variable, a two-dimensional (2D) velocity distribution in open channels was derived by maximizing the Tsallis entropy, subject to mass conservation. The derived distribution was tested using field data and was also compared with other two-dimensional velocity distributions. The Tsallis entropy-based velocity distribution was found to predict the velocity near the boundary well. DOI: 10.1061/(ASCE)HE.1943-5584.0000610. (C) 2013 American Society of Civil Engineers.
