Three-Dimensional Simulation of Flow, Salinity, Sediment, and Radionuclide Movements in the Hudson River Estuary
The three-dimensional, finite difference model FLESCOT was applied to a 106-km reach of the Hudson River estuary in New York between Chelsea and the mouth of the river. It predicted the...

A Microcomputer Program for River Sedimentation
Erosion and deposition of sediment in rivers causes numerous problems. In order to describe this process, both the hydraulic properties of the river and the mechanics of sediment transport...

SWRRB.80: A Basin Scale Model for Microcomputers
The SWRRB (Simulator for Water Resources on Rural Basins) model was developed by the USDA Agricultural Research Service to simulate the daily stream flow, and sediment loads from agricultural...

Littoral Environment Observation Program
This paper presents a method for determining the longitudinal, transverse, and vertical dispersivities of a thick aquifer for a free convection tracer test using only measurements from...

Effects of Streambed Processes on Interaction Between Surface and Groundwater
In open channel systems, the phenomena commonly referred to as 'clogging' is caused by settling of sediment and straining of suspended material as water moves...

Landform-Based Characterization of Soil Properties
A probabilistic characterization of site soil properties can be achieved with sparse site-specific data by augmenting them with data available from other sites in the region having the...

Caisson
The Jamaica Bay Water Pollution Plant was renovated and upgraded from l973-l983 and included sinking a 116 ft. x 105 ft. caisson 50 ft. deep adjacent to city streets and buildings. The...

Particle Interaction and Stability of Suspended Solids
The physics of particle interaction, which is responsible for the problem of the apparent tardy settling of suspended solids in tailings discharge slurries containing initially low concentrations...

Consolidation of Mining Wastes
This paper describes laboratory and field tests for determining consolidation properties of soft sediments, presents data on several types of mining wastes, and presents the results of...

Sedimentation and Self Weight Consolidation of Dredge Spoil
Test results suggest that self weight consolidation begins when an interface forms in the settlement column and the slurry reaches a critical concentration as a result of the solid particles...

Prediction of Viable Tailings Disposal Methods
A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for...

Convection-Diffusion Analysis of Sedimentation in Initially Dilute Solids-Suspensions
The settling of suspended solids in solids-suspensions is treated from the viewpoint of the relative fluxes established as a result of the upward diffusion of water and the downward convection...

Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...

Systems for Reducing Sedimentation in Berthing Facilities
Five systems are described which can be used to reduce sedimentation in harbor berthing areas. These systems, which are alternatives to conventional dredging, are based on either the resuspension...

Long-Term Maintenance Dredging Permits - Florida's New Approach to Regulation
Previous approaches to regulating maintenance dredging activities in Florida generally have been myopic and failed to gather information that adequately reflects the needs for environmental...

Agricultural Crop Production and Quality Effects when Soils are Amended with Dredged Lake Sediments
Lake renewal achieved by pumping loose sediment from the lake bottom requires a disposal area for that sediment and the associated water. Application of this sediment to agricultural land,...

Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...

Plant Bioassay of Contaminated Dredged Material
Contaminant mobility from a contaminated saltwater sediment placed in flooded and upland disposal conditions was studied in the greenhouse. Spartina alterniflora was grown in contaminated...

A Biogeochemical Evaluation of Disposal Options
This paper briefly reviews some of the factors that should be considered in selecting an environmentally sound disposal method for contaminated sediments on the basis of the biogeochemical...

REMOTS Sediment Profiling at the Field Verification Program
Disposal of uncapped highly polluted Black Rock Harbor muds took place in April-May 1983 at a buoy located within the Central Long Island Sound Disposal Area in 62-66 feet of water. Baseline...
