4 CONCLUSION
The Bluewater development is a prestigious, major European project. To the
author's knowledge, it includes the first reinforced soil structure designed and
constructed over a geomembrane lining. This design solution is rigorous,
innovative, and economic.
The three types of facings used for the steeply sloping lakes all exhibited
unique features. Each satisfied the design function but required different degrees
of installation manpower and time and material costs.
