Abstract

Wappapello Dam was constructed in 1938 near the New Madrid seismic region. Loose sands in the dam foundation led to concern for liquefaction and embankment sliding if a large earthquake were to occur. However it was also recognized that the operation of the dam for flood control results in relatively low reservoir levels the majority of the time, substantially reducing the risk of earthquake-induced flooding. Because of these factors, a probabilistic analysis was performed to assess the likelihood of the combination of required events leading to an earthquake-induced pool release. Results of such analyses provide better information on which to make both quantitative and qualitative judgements regarding remedial action.

Probabilistic Analysis of Earthquake-Induced Pool Release

Wappapello Dam was constructed in 1938 near the New Madrid seismic region. Loose sands in the dam foundation led to concern for liquefaction and embankment sliding if a large earthquake were to occur. However it was also recognized that the operation of the dam for flood control results in relatively low reservoir levels the majority of the time, substantially reducing the risk of earthquake-induced flooding. Because of these factors, a probabilistic analysis was performed to assess the likelihood of the combination of required events leading to an earthquake-induced pool release. Results of such analyses provide better information on which to make both quantitative and qualitative judgements regarding remedial action.
