Risk Assessment of Lake Shore Development of Devils Lake, North Dakota
In recent years, the advent of the flood insurance programs has forced developers, financiers, and planners to deal with future high water conditions and associated risks. A reliable method...

Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...

CLNET?A Computer Model for Tracking Movement, Decay, and Concentrations Throughout Water Distribution Systems
This paper describes a computer program package for modeling the spread and subsequent decay of chlorine for modeling as water travels throughout a water distribution system. This total...

Issues in Regional Water Resources Planning and Management: A Great Lakes Case Study
This paper focuses on the obstacles and opportunities inherent in regional resource management efforts, with the Great Lakes Basin serving as a case study. The following areas are addressed:...

Statistical Modeling of Space-Time Data
A common practice in hydrogeology is to draw contour lines to depict the occurrence of spatially distributed (i.e., regionalized) variables such as groundwater elevations, aquifer properties...

Movement of Chloride Ions in a Saturated Soil Sample
A series of laboratory experiments were performed to demonstrate and track the migration of chloride ions in saturated soil samples undergoing freezing. Results from these experiments...

Sport Fish Consumption Advisories in the Great Lakes Basin: Assessment of Policy to Protect Human Health
Fish consumption advisories for Great Lakes sport fish are based on U.S. Food and Drug Administration (FDA) or U.S. Environmental Protection Agency (EPA) tolerance or action levels for...

Towards a Better Simulation of Sea States for Modelling of Coastal Structures
In the last fifteen years, techniques of wave generation have advanced to such an extent that it is now possible to exercise controls of parameters such as wave grouping, wave asymmetries,...

Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...

Rock Armouring to Unconventional Breakwaters: The Design Implications for Rock Durability
This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armored slopes. The derivation and use of a suite of engineering tests for...

Reshaping Breakwaters on the Stability of Roundheads and Trunk Erosion in Oblique Waves
The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at The Hydraulics laboratory, Department of Civil Engineering, University of Aalborg....

Hydraulic Performance of Berm Breakwaters
In recent years, the concept of unconventional rubble mound breakwaters, i.e berm breakwaters, has gained much attention among researchers and engineers as an economical method to build...

Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...

Experimental and Historical Verification of the Performance of Naturlly Armouring Breakwaters
A series of hydraulic model test were carried out to investigate the mechanism by which naturally armoring breakwaters, that is breakwaters in which the initial profile is adjusted into...

Performance of a Berm Roundhead in the St. George Breakwater System
A new harbor under construction on St. George Island in Alaska's Bering Sea is using the berm breakwater concept for protection from wave attack. Three breakwaters are included...

Berm Type Armor Protection for a Runway Extension at Unalaska, Alaska
A proposed runway extension located on the Aleutian islands was designed to withstand forces of Bering Sea storm generated waves using a unique armor protection concept. The proposed runway...

Unconventional Rubble-Mound Breakwaters?Concerns
A Seminar on Unconventional Rubble-Mound Breakwaters was held in Ottawa, Canada, on the 15th and 16th of September 1987. This paper is an attempt to summarize the general discussion that...

Water Power '87
The 1980's have been characterized as an era of uncertainty for world energy including future demand for energy, fuel prices and availability, regulatory constraints, environmental...

Foam Over Troubled Toxics
Foams are now being used to control noxious vapor emissions from hazardous waste landfills. Another use of foams is in control of vapors emitted by chemical spills and fires. This article...

Pinpointing Nonpoint Pollution
The Tennessee Valley Authority is using aerial photography to locate nonpoint sources of water pollution. These cause most of the water quality problems in the region. Failing septic tanks...
