One-Dimensional Velocity Distribution in Open Channels Using Tsallis Entropy

Assuming time-averaged velocity as a random variable, a one-dimensional velocity distribution for wide open channels was derived by maximizing the Tsallis entropy, subject to mass conservation. The derived distribution was tested by using field and experimental data and was also compared with other well-known velocity distributions. The Tsallis entropy-based velocity distribution was found to predict the velocity near the bed well.
