Suction Controlled Penetration and Shear Tests

The Boundary Layer Downstream of an Interrupted Suction Slot

Using Suction to Minimize Sand-Bed Scour
An unprotected cylindrical pier was exposed to the erosive forces of unidirectional currents with superimposed waves traveling with or against the current. The same set of tests was repeated...

Soil Moisture as a Factor in Subgrade Evaluation
The pretesting treatment is for the purpose of providing soil specimens having moisture conditions similar to those under the pavements. This is a necessary step in the laboratory evaluation...

Jet Boosting in Hydraulic Dredging
The introduction of a jet boost into the suction line of hydraulic dredgers is employed widely, the objective being to enhance production without increasing the capacity of the main dredge...

Local Erosion Caused by Rapid Forced Infiltration
Examination of the stream bed over a water intake buried beneath it revealed a scoured hole with a dune downstream. Laboratory experiments result in the same kind of feature, providing...

Influence of Suction and Blowing on Entrainment of Sand Particles
The influence of suction and blowing on the rate of entrainment of sand particles was studied experimentally. For the range of grain sizes (130 - 570 μm) suction always reduced sediment...

Flow Field Surrounding a Suction Pipe Inlet

Water Deficits—Irrigation Design and Programming
Irrigation system design and economic analysis of proposed irrigation schemes require quantitative prediction of relationships between crop production and water use. In keeping with recent...

Simulation of Post-Irrigation Moisture Movement
The transpiration-induced moisture removal by the plant roots is represented by a negative source term in the Darcy equation. When the soil is wetted to near saturation, the moisture flow...

Breakout Resistance of Objects Embedded in Ocean Bottom
Soil resistance to withdrawal is found to be greatly affected by failure patterns. For relatively shallow anchors in undisturbed dense and stiff soils general shear along a convex, torical...

Dredging Methods for Deep-Ocean Mineral Recovery
A great deal of interest has been generated in recent years in possible recovery of minerals from the marine environment. Mineral resources of the sea are listed and the most promising...

Supership Effect on Waterway Depth and Alignments
Superships require special deep-water berthing and moorings, and special alignments of channels. Their wide bams, flat bottoms, restricted maneuverability, long stopping distance and associated...

Experimental and Numerical Study of Column Drainage
The status of research studies concerned with the vertical drainage problem is examined and the need for additional work on the comparison between measured and predicted water content...
