摘要

This research revealed the intangible benefit of preserving the downdrift eroded shoreline at Cha-Am beach, Thailand. It integrated coastal engineering and environmental economics to urge for the beach restoration. Although providing some benefits, the jetty at Cha-am beach has also created severe downdrift coastal erosion. The research began with gathering the field data required to simulate the future shoreline position. After a satisfactory model calibration was attained, the future coastline change was predicted. It was found that the updrift part of the beach would be widened by approximately 8 m/yr, while the downdrift side of the jetty would experience severe coastal erosion by as much as 13 m/yr. A valuation of the downdrift eroded shore was consequently undertaken using a willingness-to-pay (WTP) study. Four hundred sets of questionnaires were surveyed using 10 different bid amounts. A logit model was implemented and the mean WTP was analyzed. It was found that the value of the downdrift eroding shoreline was approximately THB 20.1 billion or USD 609.9 million per year. Such a huge non-market value of the downdrift beach might urge decision makers to initiate certain continuous beach restoration measures.
