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...
Hypsometry as a Tool for Calculating Coastal Submergence Rates
A contemporary rise in relative sea level is slowly submerging the outwash plain which lies behind Long Island's barrier beaches. While relative sea level change rates vary...
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...
Longterm Changes of Tidal Regime in the German Bight (North Sea)
Sea level changes are caused by astronomical tides (periodical changes), meteorological, geological and oceanographical conditions, vertical movements of the earth's crust...
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...
Simulation of Marsh Growth Under Rising Sea Levels
A method for computation of the rise of a marsh surface is presented that includes the effects of tidal and sea level variations, aggregation and deposition of cohesive suspended sediments,...
Using Microcomputers for Groundwater Flow Analysis
Micro-computers offer an effective and efficient method for rapid and comprehensive analyses of groundwater flow. There are now numerous codes which have been developed specifically for...
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,...
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...
Mackenzie River Breakup: Ft. Simpson to Ft. Good Hope, N. W. T.
Breakup progression on the Mackenzie River in 1982 and 1983 is described. Two types of breakup, and two types of ice jam formation associated with these, were identified. The major role...
Stochastic Analysis and Modeling Levels of a Land-Locked Lake for Resource Development
Lakes are valuable natural resources that can be tapped for recreational, agricultural and other extensive lake side developments. Natural variability of lake levels is an important factor...
A New Panama Canal?
The Panama Canal is expected to be obsolete by the end of the century. Already there are serious problems with ship traffic through the Canal: volume of traffic is down, average transit...
Pier Stabilization Eliminates Need to Reconstruct Damaged Bridge
After an ice jam near a six-span bridge restricted normal water passage, the ensueing high velocity water caused underscouring of one of the piers, leaving it ineffective as a bridge support....
Multimillion-Acre Tea Bag
Just as pouring the same cupful again and again through a tea strainer makes bitter tea, so irrigating again and again with return-flow water concentrates salts in the water supply. While...
Atlanta's New Airport Terminal�One Year Early, Within Budget
At Atlanta's new airport terminal complex the landside functions (ticketing and baggage) are in a two-building complex, and the airside activities (airplane gates and waiting...
Best Ways to Dewater Dredged Material
Left to its own devices, fine-grained dredged material placed in confined disposal areas reaches an equilibrium water content near its Atterberg liquid limit. The high water content of...
Intermediate Service Levels in Water Distribution
This paper is concerned with design standards for secondary water distribution networks. Based on field studies in the Middle East and Africa, mathematical equations were developed for...
Hydraulic Fill Dams/Earthquake Stability
The 1971 San Fernando earthquake near Los Angeles, Calif., generated concern for the stability of hydraulic fill dams. Two dams located near the fault were damaged severely. The shaking...
