Summary: Inflatable flexible membrane dams (IFMD) have been used
for the past 40 years in river and coastal engineering
applications. Despite an increasing interest for IFMD, little
information is available on the hydrauli performances of IFMD
during overflow periods. Overflow situations may occur with
deflated or inflated membranes. Both situation are described. It
has been recognised that overflowing waters may induce some form of
fluid-structure interactions, which might cause vibrations of the
IFMD structure, leading to damage or destruction of the membrane.
Several flow instability mechanism are reviewed and associated
hazards are discussed. For overflow situtations above inflated
dams, new flow calculations are detailed and the results give new
information on the wall pressure distribution along the downstream
face of the dam. A mechanism of cavitating flow separation is also
explained.

13 pages, Brookhaven National Laboratory, Upton, NY The evaluation of the potential for slope sliding and/or liquefaction failure of earthen dams subjected to earthquake loadings is most often based on deterministic procedure of both the excitation input and of the physical model. Such treatment provides answers in the form of either factor of safety values or a yes or no as to whether liquefaction will occur or not. Uncertainties in the physical...
