A large industrial facility in the west of France was impacted by a flood in January 1995. Costs associated with the disruption in one week of production were estimated at $15E6 US. In response to that event, Woodward-Consultants International (WCI) was retained to design remedial measures to prevent a flood recurrence that would affect production. In addition to estimating the 100-year flood and designing a perimeter wall, the effects of a rise in the groundwater table under the site were also evaluated. This paper discusses the investigative efforts and computer modeling results aimed at estimating the change in groundwater levels over time along the site perimeter and the recommendations made to address the problem.
