Abstract: Levee seepage analysis for design often uses steady-state analyses, which produce conservative results. Transient seepage analyses are appealing because they can account for time-dependent flood loadings. Uncoupled transient ...

Abstract: External water level variations, such as rapid drawdown or flood loading, change the internal pore pressures in an embankment as a result of changes in the boundary conditions. Three different effects result: (1) changes ...

Abstract: Following Hurricane Katrina an extensive investigation of the performance of floodwalls in the New Orleans area was undertaken by the U. S. Army Corps of Engineers and others. This investigation included detailed study of ...

Abstract: The U.S. Army Corps of Engineers’ blanket theory has been successfully used to evaluate levee underseepage for many years. The method was developed from closed-form analytical solutions based on the principles of groundwater ...

Abstract: Consolidated-undrained tests on saturated compacted clays are used to provide strengths for design scenarios such as rapid drawdown, rapid flood, and earthquake loading of dams and levees. Geotechnical engineers have long ...

Abstract: TWO subdivisions in southern California constructed on compacted‐sandy‐clay fills up to 100 ft thick experienced settlement damage several years after construction. These fills were designed and constructed using the same ...

Abstract: Slope stabilization procedures for six landslides in the Niigata prefecture in Japan afforded an excellent opportunity to examine the residual drained shear strength of weathered mudstones. Installation of 3 m diameter ...

Abstract: The engineering behavior of low-plasticity silts is more difficult to characterize than is the behavior of clay or sand. Due to their tendency to dilate during shear, establishing a consistent and practically useful failure ...
