Stochastic Uncertainty in a Dam-Break Experiment with Varying Gate Speeds
Journal of Marine Science and Engineering, 2021 Uncertainties inherent in gate-opening speeds are rarely studied in dam-break flow experiments due to the laborious experimental procedures required. For the stochastic analysis of these mechanisms, this study involved 290 flow tests performed in a dam ...
