Developing Findings of Fact for a Hazard Mitigation and Preparedness Plan for the City of Waldport/Alsea Bay Area, Lincoln County, Oregon
Marine erosion attributed to the effects of the 1983 El Nino resulted in the loss of the distal tip of Alsea Spit in 1985 enlarging Alsea Bay inlet by 300% and subjecting the City of Waldport...

Assessing Changes and Their Real Impact

The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...

Building a Team, Not Just a Building
The best way to resolve construction disputes is to head them off. And the best time to step in is before your contractor is hired. In the private sector, there is no reason to open the...

Long-Range Forecasts of Water-Supplies
Many engineers and water-users have an urgent need for reliable predictions of future rainfall and water supplies, extending many months or years ahead. Correlation of known historic rainfall...

Considerations in Applying the 1985 HCM Procedures
The paper examines the impact of critical assumptions in the 1985 Highway Capacity Manual (HCM) procedures on the resulting measures of effectiveness -- volume/capacity ratio, delay, and...

Estimating Future Traffic Volumes at the Intersection Level
This paper uses the experience gained on a number of regional and sub-area studies in the northeast to illustrate how measured and forecast traffic information can be combined to predict...

Trip Table Estimation from Observed Traffic Volumes
This estimation technique identifies the most likely trip table to produce a specified set of traffic counts when assigned to a representative highway network. The resultant table is derived...

Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...

Evaluation of Safety Alternatives by Benefit/Cost Analysis
There is an increasing awareness of the need to use limited highway safety funds on projects that offer the greatest benefits. This paper describes the development and application of a...

Design & Construction With Shrinkage-Compensating Concrete Using ACI 223-83

Response of Great Salt Lake to Climate Variability
Levels of Great Salt Lake, Utah, have fluctuated through a range of 6. 2 m in the historic record since the 1840s. In water years 1983-1984, the lake rose 2. 9 m in response to record...

Estimating Climate Change From Hydrologic Response
In the eighty-one hydrographically closed basins within Nevada many large lakes developed during the pluvial climate of the Pleistocene. Pluvial lake area and tributary basin area have...

Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...

Stochastic Design of Wastewater Storage Ponds
The authors combine the principle of mass conservation with basic ideas from probability theory and then apply Monte Carlo simulation techniques to develop a family of design charts called...

Changes in Management: International Great Lakes
Unprecedented changes in the binational management of the Great Lakes are underway. Problems and programs to solve them increasingly are being considered on an ecosystem (comprehensive,...

The Training of the Owner
Engineers would do well to explain to their clients just what the role of the engineer is. The place to start is with one's ability to produce a perfect set of plans. Imperfections...

Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...

Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...

The Recovery of Monterey Bay Beaches After the Winter Storms of 1982-83
The El Nino conditions of 1982 and 1983 produced unusually frequent and intense storms along the central California coast. These storms produced much greater than normal beach erosion...
