Dynamic Momentum Concept in Improving Analuytical Dam Break Model

Abstract
Dam-sluice operation (or dam break) represents a crucial flood control mechanism for our environment. However, majority of current studies lacking in precision to simulate such important flow phenomenon. This study incorporates an advance and novel flow velocity shift approach to an analytical dam break model to account the dynamic impact of a sluice gate opening. The generated results provided evidences that the velocity shift directly impacts the upstream and downstream locations of the dam break wave. The results illustrate that such intense explicit analytical solutions are best suited for flows of turbulent nature, rather than that of laminar nature. Additionally, the study presented an illustration of the potency of the reduction factor α within laminar dam break waves. Various experimental measurements are adapted to validate the proposed model. The improved model provided potent evidence that the estimation of the dam break wave front location experiences a significant increase in accuracy in comparison to other models in the previous studies.
