Draghead Designs vs. Production
This paper discusses the development and design of draghead configurations for silt materials and describes a testing program designed to determine the most efficient range of the controllable...
Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
Reservoir Outlet Extended Above Silt to Prevent Clogging
Accumulation of silt in an on-stream water storage reservoir almost completely buried the concrete tower originally provided as an outlet intake shaft for releasing stored water through...
Recording River and Reservoir Water Depth
At the Kerr Reservoir on the Roanoke River in Virginia and North Carolina, reservoir bottom was surveyed before reservoir filling and twice thereafter, to determine rate of siltation....
Vibroreplacement and Reinforced Earth Unite to Strengthen a Weak Foundation
Two relatively new engineering concepts in the U.S. were successfully used to solve a difficult soils problem. A highway skirting Idaho's Lake Pend Oreille was built on a...
Channel Siltation Determined with Side-Scan Radar
Of the new electronic means to measure water depth, side-scan sonar is unusual in that it gives not just a cross-section of the bottom but a semi-3-D picture of the bottom surface. Experienced...
