Effect of uncertainties in breach location and breach mechanisms on risk‐related classification of off‐stream reservoirs

open access: yesJournal of Flood Risk Management, Volume 18, Issue 1, March 2025.
Abstract Off‐stream reservoirs are artificial water storage structures that increase the flood risk of an area. In some places, related risk reduction plans are based on a risk classification of these structures, which follows local water resource management regulations. These classification methods typically follow deterministic qualitative guidelines
