The instability theory of drumlin formation and its explanation of their varied composition and internal structure
Despite their importance in understanding glaciological processes and constraining large-scale flow patterns in palaeo-glaciology, there is little consensus as to how drumlins are formed. Attempts to solve the ‘drumlin problem’ often fail to address how they are created from an initially flat surface in the absence of obvious cores or obstacles. This is a key strength of the instability theory,...
متن کاملAn instability theory for the formation of ribbed moraine, drumlins and mega-scale glacial lineations.
We present a theory for the coupled flow of ice, subglacial water and subglacial sediment, which is designed to represent the processes which occur at the bed of an ice sheet. The ice is assumed to flow as a Newtonian viscous fluid, the water can flow between the till and the ice as a thin film, which may thicken to form streams or cavities, and the till is assumed to be transported, either thr...
متن کاملNonlinear Instability of Coupled CNTs Conveying Viscous Fluid
In the present study, nonlinear vibration of coupled carbon nanotubes (CNTs) in presence of surface effect is investigated based on nonlocal Euler-Bernoulli beam (EBB) theory. CNTs are embedded in a visco-elastic medium and placed in the uniform longitudinal magnetic field. Using von Kármán geometric nonlinearity and Hamilton’s principle, the nonlinear higher order governing equations are deriv...
متن کاملEffects of electromagnetic field on the dynamical instability of cylindrical collapse
The objective of this paper is to discuss the dynamical instability in the context of Newtonian and post Newtonian regimes. For this purpose, we consider non-viscous heat conducting charged isotropic fluid as a collapsing matter with cylindrical symmetry. Darmois junction conditions are formulated. The perturbation scheme is applied to investigate the influence of dissipation and electromagneti...
متن کاملMORPHOLOGY OF DRUMLINS: A COMPARATIVE ANALYSIS OF SELECTED DRUMLIN FIELDS IN NORTH AMERICA Morphology of Drumlins: A Comparative Analysis of Selected Drumlin Fields in North America
Pleistocene glaciers revealed numerous types of land formations in their retreat northward during climatic warming. The postglacial landscape contains various features, such as moraines, flutes, and drumlin fields. Drumlin fields in southeastern Wisconsin and west central New York are compared in terms of drumlin morphology to ascertain regional differences between drumlin fields formed by diff...
