Climate Risk Portfolio Screening of 83 Sluice Gates in Kien Giang Province, Vietnam

This report is the end result of a climate risk assessment (CRA) for the coastal sluice gate system in Kien Giang. The objective of this work package is to develop a set of standard but up-scalable criteria for the assessments of other cases of sluice gate system in Mekong Delta in general and Kien Giang province in particular. As sluice gate itself is adaptive infrastructural component of the entire sluice gates system in every locality, with function to regulate salt-fresh water in the context of climate change, the assessment results and recommendations of this work package are expected to provide inputs and solutions for a harmonised operation and maintenance for the current sluice gates and design for future sluice gates. To achieve the above objectives, this report has developed a rapid CRA method (namely PIEVC Scanner) for the coastal sluice gate system in Kien Giang province based on a similar process to the PIEVC Protocol, including five major steps of project definition, data gathering and sufficiency, risk assessment, engineering analysis, and recommendations.

An advantage of PIEVC Scanner is the ability to assess the responses of infrastructure components for each infrastructure group (e.g., monolithic concrete or
pillar dam) under the impacts of climate and hydrological factors in different geographical regions. As a result, the PIEVC Scanner will provide the corresponding risk matrices for different climate and hydrological regions.
