In order to mitigate the flood, weirs were also used as the flood mitigating structures but no study has been found in which efficacy of energy dissipators downstream of weirs is checked either experimentally. Present work is an attempt to study the

Assessing drag force and Reynolds stresses in turbulent flows is crucial for evaluating the stability and longevity of hydraulic structures. Yet, this task is challenging due to the complex nature of turbulent flows. To address this, physical models
