Abstract: Two simple shear apparatus (SSA), the Cambridge University SSA Mk7 and an NGI type, were used to compare the radial stresses developed in the NGI‐type SSA with the horizontal normal stresses on the plane perpendicular to ...

Abstract: This paper presents the formulation of the mechanics governing the changes in stress state from groundwater pumping. A two-layer alluvium consisting of a cemented alluvium layer on top of an unconfined aquifer alluvium ...

Abstract: Seepage erosion—in particular, slope failures (bank slumps, mass wasting)—is prevalent on most sandbars downstream from the Glen Canyon Dam, Ariz. The public is concerned about the loss of the extant biomass and recreational ...

Abstract: Previous researchers have treated the magnitude and direction of the seepage vector as independent variables and found that seepage, parallel to the surface, does not result in the minimum stable seepage slope. In the ...

Abstract: The Glen Canyon Dam, located in the northeastern corner of Arizona, is operated to satisfy peak power demands of neighboring states. The discharge regime of the dam is such that the river stage in the Colorado River ...

Abstract: The effect of fluctuating discharge from Glen Canyon Dam on downstream sandbars is of significant concern to dam operators, environmentalists, and the public. In this contribution, the observations of seepage-related erosion ...

Abstract: The results of an alternative procedure to the

Abstract: A technique is presented for determining the electrode configuration required for developing a subsurface electric field with specific direction and intensity. The complex potential offers a convenient means to describe ...
