The Ultimate High Tide
Unprecedented consumption of fossil fuels and clearing of vegetation have spurred interest in the greenhouse effect. Under this scenario, a build-up of carbon dioxide and other gases in...

The Impact of Selected Sea Level Rise Scenarios on the Beach and Coastal Structures at Sea Bright, N.J.
The physical impacts of selected sea level rise scenarios on the shoreline of Sea Bright, New Jersey, are investigated. The sea level rise scenarios chosen for investigation were developed...

Water Use Forecasting and Evaluating the Effects of Conservation Measures
The City of Austin, Texas, instituted mandatory restrictions on water use during a summer drought in 1984 when water use levels beyond 150 million gallons per day stressed the city's...

Regional Target Level Modification for Groundwater Quality
A procedure for modifying an optimal regional potentiometric surface designed solely on the basis of quantitative considerations, is described. These modifications are based on quality...

Direct Filtration of High Turbidity Water Using Contact Flocculation
It is shown that the system of bed contact flocculation followed by standard dual media filters provides a viable alternative to both conventional as well as direct filtration, particularly...

Streamflow Losses, Consequent Flow Through a Thick Unsaturated Zone, and Recharge to an Unconfined Aquifer
Two experiments were conducted in conjunction with a 23-day aquifer test made in south-central Arizona to determine (1) water loss from a natural channel and (2) flow through a 330-foot-thick...

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...

A Tidal Gauge System in New York Harbor
For over a year, a Real Time Wind and Water Level Telemetry System (RTWLTS or Tidal Gauge System) in New York Harbor has been generating real time data 24 hours per day on actual harbor...

Sea Level Rise and Wetland Loss
Increasing concentrations of carbon dioxide and other gases are expected to raise global temperatures several degrees in the next century. Such a global warming could raise sea level a...

Litigating the Invisible Boundaries of Tidelands and Wetlands
The author urges uniformity in standards for establishing the two invisible lines that are dominant in coastal law, i. e. , the main high water line and the wetlands line. A high degree...

Rising Sea Level, Storms, and Coastal Erosion at Ocean City, Maryland
This paper describes the 'greenhouse effect', and its impact on future sea level rise; provides an overview of the possible impacts on Maryland and other coastal...

A Microcomputer System for Processing Analog Hydrologic Data
Microcomputer software was developed to digitize, filter, and view data from analog charts of gate operation and water level before being transmitted to a mainframe computer for data base...

Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...

Lake Water Level and Sediment Management—Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...

A Self-Updating Algorithm for Real-Time Flood Forcasting

Response of a Meandering River to Artificial Modification

Cutoff Bendways and the Legal Dilemma Regarding Property Ownership

Evaluation of a Contaminated Aquifier's Restoration Potential

Economics of Groundwater-Pumping Level Statutes
Pumping from one well may lower the water table in another to the point where pumping from it becomes unfeasible. Problems exist in allocating the increased costs of pumping caused by...

Overtopping of Flood Control Levees and Floodwalls
The risk of overtopping can be significant for flood control levees or floodwalls, and the consequences can be costly and potentially catastrophic. Designs using superiority can force...
