Verification of Reproducibility of Overflow/Breakwater Flow and Flow Rate by Integrated Flood and Inundation Analysis With Water Level as Boundary Conditions

Key Points

• The aim is to verify the reproducibility of overflow and breakwater flows using integrated flood analysis with water level as boundary conditions.
• Conducted stationary and unsteady experiments on overflow and breakwater flows.
• Used experimental results to assess the accuracy of flood and inundation analysis.
• Evaluated flow rates and surface profiles during overflow and breakwater occurrence.
• Flood and inundation analysis generally replicates flow rates during overflow events.
• Reproducibility of flow and surface profiles decreases near breaching areas due to inadequate energy loss evaluation.
• Findings highlight the need for improved models to better assess flows surrounding breaching sections.
