Abstract

Plain of Reeds, a wetland of Mekong Delta of Vietnam has a very special geologic feature. This area is a contiguous zone between ancien and new alluvia layers which cause sudden change of geology; in addition, the density of river and canal is very high. Because of the geologic alterability and design mistakes, many incidents of traffic constructions have occurred in the Plain. Statistically, most of the incidents are from the careless geology survey and the subjectiveness of designers. This paper presents some road and bridge incidents in the Plain, causes, and recovery plans. The article also proposes solutions for new traffic constructions in such environnment.
