Abstract

This Report documents key observations of a reported flooding incident that occurred at the Shatin Hospital in October 2016. The flooding incident was probably caused by the blockage of stream flow due to presence of a steel flexible barrier which had trapped significant amount of stream loads. This study covers a review of overseas design practice and technical guidance on the use of flexible barriers traversing across a stream course. Based on the findings of this study, preliminary recommendations pertaining to the detailing of flexible barriers that traverse a stream course are provided, with a view to minimising trapping of stream loads.
