Consolidation of Permafrost upon Thawing
Methods of predicting initial consolidation upon thawing and the subsequent consolidation with time under increasing pressures are presented in terms of changes in unit weight. Procedures...
Monitoring of an Ocean Dredged Material Disposal Site
The Tampa Harbor Project involves deepening and widening approximately 50 miles of existing shipping channel in Tampa Bay, Florida, with the removal of approximately 70 million cubic yards...
Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...
Shoaling Problems and Improvements Sunny Point, North Carolina
The Military Ocean Terminal, Sunny Point (MOTSU), is located on the Cape Fear River, approximately 18 miles downriver from Wilmington, North Carolina. The facility has experienced significant...
The National Dredging Data Management System
The ADDAMS computer program is a collection of user-friendly computer models for planning, designing and managing confined disposal areas. Models which can be used to determine the size...
Linear Programs for Dredging Management Decisions
Recurrent economic concerns facing decision makers in the dredging industry are considered. Problems related to contract bidding, project planning and resource utilization are formulated...
Soil Analysis and Dredging
Analysis of soils before dredging can make or break a dredging project. It is seldom possible to obtain all of the information needed for selecting equipment and estimate outputs. The...
An Application of Acoustic Core Analysis
This technique has shown itself to be extremely successful at Roberts Bank, in a highly variable bottom material, where shallow depths were not a significant problem, and some borehole...
Hydraulic Uncertainty in Risk Analysis
Considerable effort has been expended in defining and evaluating hydrologic uncertainties; however, the analysis and evaluation of hydraulic uncertainties has received little attention....
Analysis of Partially Filled Circular Storm Sewers
The classic design approach uses Manning's formula. Comparisons between analytical results obtained in this manner and the many available experimental results indicate substantial...
Accurate Computation of Nonlinear Advection
Advection, the transport of a quantity by the mean velocity, is a process which appears in virtually all equations of free-surface hydraulics. The demonstrated accuracy and efficiency...
Stability of Method of Characteristics
For the analysis of waterhammer, the first-order accurate method of characteristics (MOC) has been widely used for which Courant condition for stability has been developed neglecting the...
Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...
A Three Dimensional Hydraulic Jump
A study is conducted to define the three-dimensional hydraulic jump that occurs in a rectangular channel downstream of a rectangular contracted sluice gate. A sequent depth ratio equation...
Reservoir System Management for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...
Unsteady Mixing of a Buoyant Jet into a Reservoir
A buoyant effluent was dyed with fluorescent dye on two occasions to determine its mixing characteristics and flow path through a small hydropower reservoir located in south central Arkansas....
Thermal Breakup Predictions on a Regulated River
The thermal breakup process which occurs on the Peace River in Alberta, Canada is described. A quantitative technique which uses the energy budget to explain the celerity of the breakup...
Simulation of River Ice Cover Growth and Decay
A model of ice cover thermodynamics was used to simulate ice growth and decay along the international section of the St. Lawrence River for the winter of 1980-81. At the air-ice interface,...
Mathematical Modeling of River Ice Process
Computer modeling of flow and ice conditions in a river is an important element in the planning of water resources project in northern regions. River ice processes are closely related...
The Importance of Nonlinear Wave Interactions Under Ice
Waves under ice interact at the second order in wave slope. Because of this, a monochromatic wave train impinging on an ice sheet can transfer a significant amount of energy to its own...
