Validation of SWRRB?A Simulator for Water Resources in Rural Basins
The three major components of SWRRB are weather, hydrology, and sedimentation. Processes considered include surface runoff, return flow, percolation, evapotranspiration, transmission losses,...
Surface Erosion Control on Roads in Granitic Soils
The impact of forest road construction on water quality and fish habitat is a serious problem for engineers, hydrologists, and foresters. Control of surface erosion is an important and...
Modeling Off-Site Impacts
The off-site impacts of a flood water control program were evaluated by applying the SWRRB (Simulation of Water Resources on Rural Basins) model to a treated basin, primarily agricultural,...
Prediction of Nutrient and Heavy Metal Transport Capacities of Suspended Sediment in the Southwestern United States
SEDCON, a computerized prediction technique (using forest type and geology as inputs) has been developed to estimate the impacts of land management practices on physical and chemical characteristics...
Application of Phosphorus Models to New Mexico Reservoirs
Many empirical, mass-balance phosphorus models have been developed and tested on northern, temperature lakes and previously published. Fourteen of those published models were tested on...
Microcomputer Application in Predicting Upland Erosion
An erosion-deposition model, originally developed for a mainframe computer, was adapted for an Apple IIe. With minimal adjustment it can also be used on other personal microcomputers....
Fate and Transport of Metals in a River System
A steady-state model was developed that describes the fate of metals in a shallow river system. Settling and resuspension of solids were defined through empirical equations relating a...
Understanding Secondary Clarifier Behavior
The author has developed a graphic procedure for analyzing the hydraulic behavior of settling tanks. Data have been used in numerous cases to devise low cost in-tank and external improvements...
Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
Four sectors of the western Adriatic coast, each with a different feature, represent the test areas to evidence the differences between the two textural classifications of sediments by...
Contained Dredged Material for Open Ocean Disposal
An intensive series of investigations were conducted on the sediments deposited in Craney Island, a 1012 hectare contained disposal facility in the Port of Hampton Roads, VA. Geographic...
Dredge Material Evaluation Through Harbor Characterization in New England
The New England Division (NED) of the Corps has recently developed a broad based methodology for simultaneously evaluating dredging projects that are in close proximity and which would...
A New Method for Effective Beach-Fill Design
Beach nourishment with sand fill has been extensively used to restore recessional beaches, but the success of this method has been variable due to a poor understanding of sediment dispersion...
Guidelines for Beach Nourishment: A Necessity for Project Management
This paper outlines detailed studies that have been performed on recently completed projects to assess the fill sediment redistribution and profile response. This compilation of data has...
Dune Construction on Perdido Key, Alabama
In recent years, the Alabama coast has experienced significant pressures for development. To make development compatible with beach preservation, the Alabama Department of Environmental...
Low-Cost Stacked Block Revetments for Great Lakes Shores
Two stacked-block revetments, the product of emergency conditions and budget limitations, were constructed at Illinois Beach State Park on Lake Michigan in April 1982. The revetments,...
Studies in an Unproductive Coastal Lagoon in South Texas: A Case Against One-Time Sampling for Environmental Assessments
This study illustrates the problems inherent in attempting to write an environmental assessment based on inadequate or misleading data. Results can be biased against environmental preservation...
Sea-Level Rise and Marsh Vertical Accretion Rates in Chesapeake Bay
Chesapeake Bay marshes, in their wide variety of vegetation types, salinity ranges, and environmental settings provide a unique perspective on the relations between marsh vertical accretion...
Modification of the Sedimentary Environment During Construction of the Hart-Miller Island Diked Disposal Facility
The state of Maryland contracted for the construction of a diked disposal facility. Research investigations were conducted to assess the impact of the dike construction on the environment...
Geomorphic Processes and Stability of Coastal Wetlands
Theoretical stability analyses of coastal wetland systems typically show that the key determinant of stability is the rate of operation of geomorphic processes. This implies that if the...
The Suwannee River Estuary: Cohesive Sedimentation
Cohesive sediment dynamics as effected by salinity intrusion are described for the Suwannee River Estuary, a large estuary flowing over the very shallow limestone shelf of Florida's...
