Numerical modeling of tides in the late Pennsylvanian Midcontinent seaway of North America with implications for hydrography and sedimentation
, JOURNAL OF SEDIMENTARY RESEARCH, Vol: 77, Pages: 843-865, ISSN: 1527-1404A novel numerical model (the Imperial College Ocean Model, ICOM) is used to simulate tidal circulation in shallow epicontinental seas connected to large, open oceans. ICOM is validated using the present-day North Sea and applied to predict tidal range in the late Pennsylvanian Midcontinent Seaway (LPMS) of North America. The model simulates the effect of the principal tidal constituents (astronomical tides) as well as the tide propagating from the adjacent open ocean (co- oscillating tide). Two ‘‘base-case’’ Pennsylvanian paleogeographies were tested: (1) a maximum sea-level highstand and (2) the early stages of a transgression. Sensitivity tests determined the importance of paleo-water depth and coastline uncertainty on the prediction of tidal range. During the highstand, tidal ranges in the craton interior (Midcontinent Shelf, Illinois and Appalachian basins) are consistently predicted as microtidal (, 2 m tidal range). Such low tidal ranges would have inhibited water-body mixing in the LPMS, promoting stratification. This, combined with the influx of oxygen-poor water from the Permian Basin to the west and high organic input from tropical rivers, may have contributed to the deposition of ‘‘core’’ black shales in LPMS cyclothems. Conversely, a mesotidal to macrotidal diurnal (once-daily tide) regime is predicted for the early transgression in a large-scale embayment in eastern Kansas due to resonant amplification of diurnal tidal constituents. Pennsylvanian strata here have been ascribed to a mesotidal to macrotidal setting and include cyclic rhythmites that suggest a strongly diurnal system, as predicted by ICOM.

The pre-failure deformation of an embankment predicted by two kinematic hardening models
, Pages: 447-453This paper presents a comparison of the pre-failure behaviour of an embankment when its clay foundation is modelled with two kinematic hardening models. The paper shows that the pre-failure deformations are not only influenced by non-linearity but also by the stiffness response predicted in both compression and extension paths. © 2006 Taylor & Francis Group.

The effect of compaction on bulk permeability of stiff clay and mudrock - Field experience from embankment dams
, Pages: 797-807The permeability of in-situ clays and soft mud rocks is strongly affected by slightly open fissures. These are difficult to discover from site investigation as the permeability of the parent intact material Is very low. This is measured by laboratory tests and, often, by in-situ tests. It is difficult to prove the absence of open fissures and low bulk permeability. This causes uncertainty in the use of these materials as impermeable seals. However, field experience is that when these materials are placed as fills using modern plant, a uniform low permeability results. There is much experience in the construction of the cores and fills of embankment dams. This experience is reviewed.

Paper: The bearing capacity of a circular footing under 'punch-through' failure
, Ground Engineering, Vol: 39, Pages: 42-44, ISSN: 0017-4653Finite element analyses performed with the Imperial College Finite Element Program (ICFEP) were carried out to perform a parametric study of the bearing capacity of a circular footing on layered clays. Eight noded isoparametric solid elements and six noded, zero thickness interface elements were used with reduced integration. A modified Newton-Raphson approach with an error controlled sub-stepping stress point algorithm was used to solve the non-linear FEAs. The data generated showed existing methods of analysis to predict overly conservative foundation capacities.
