Use of rubber dams for flood mitigation in Hong Kong - Discussion

The writer is encouraged that more and more inflatable dams are being built in the world for a wider variety of purposes. Both Vietnam and Bangladesh recently saw their first inflatable dams. In addition, higher dams are also possible. The writer wishes to point out that apart from the dam's capability for flood mitigation there are other notable advantages. Inflatable dams may be installed in extremely cold climates. Steel gates may be "frozen" (gate jamming) under such temperatures, whereas inflatable dams are still operable. Another problem associated with "frozen" steel gates is the flooding upstream caused by ice formation at the steel gates. Broadwater Dam, Missouri River, Montana (Bridgestone 1982, 1997) is an example of such an application in a cold climate.
