Analysis of Transient Seepage Through Levees
… methods of evaluating levees with respect to seepage, erosion, piping and slope instability. Transient seepage analyses provide an effective method of evaluating seepage through levees and its potentially destabilizing effects. Floods against levees usually last for days or weeks. In response …

Transient Seepage Analysis for Levees and Dams: Numerical and Monitoring Approaches
An investigation into the transient impacts of flood loadings on earthen embankments was conducted. Two embankments were instrumented and monitored over a period of four years. One of these embankments was a levee located along the Mississippi River just north of Cairo, Illinois. The other …

The relationship between slope stability and pore-water pressure in highly plastic clay in the Carrot River Basin
… head versus time boundary condition for the transient groundwater seepage model. Factors of safety were calculated throughout the course of the flood event with pore-water pressures characterized by the transient seepage model. Factors of safety predicted with the transient seepage model …

Effects of Reservoir Releases on Slope Stability and Bank Erosion
… determined by each of the methods was used for transient seepage modeling and the modeling results compared to the actual ground water table measured in the field. The results indicate that although the hydraulic conductivities determined by in situ tests were much larger than those typically …

Rapid Drawdown Analysis using the Finite Element Method
… analysis of RDD, especially using uncoupled transient seepage analysis, was shown to be inappropriate because important aspects of soil behavior are ignored. Consolidated-undrained strength tests on compacted clay specimens highlighted the importance of relative compaction on undrained …

Ground Improvement for Liquefaction Mitigation at Existing Highway Bridges
… of their inability to adequately account for the transient response. Equivalent-linear dynamic response analyses indicate that significant shear strains, pore water pressures and accelerations will develop in the improved ground when the treated-untreated soil system approaches resonance during …
