Remediation Site Prioritization by the Risk Ranking and Filtering Method
The risk ranking and filtering (RRF) method, developed for ranking critical components of the NASA Space Shuttle, is a possible framework for the prioritization of hazardous-waste sites...
Quantifying Uncertainty in Site Characterization
The uncertainties in determining the true geologic conditions at the proposed high-level nuclear waste repository at Yucca Mountain, Nevada needed to be determined as part of the Exploratory...
Geotechnical Database Manipulation to Effect Stochastic Analysis
Existing or easily-developed databases of regional geotechnical information can be used to estimate prior probability distributions and parameters for use in stochastic analyses. Prior...
Engineering of Controlled-Drainage Systems
Soil-water management by water table control (via a dual purpose subdrainage-subirrigation system) is becoming popular in humid regions of the U.S. and Canada. Controlled-drainage is an...
Optimizing Economic Returns in Drainage Design
Soil wetness is a limitation to high agricultural productivity in Northern New York (NNY) where some 325,000 ha of cropland require drainage treatment. Drainage is needed for trafficability...
Agricultural Drains and Safety of Dams
Bonny Dam is located in east central Colorado on the South Fork Republican River. The dam's foundation is in the relatively porous Ogallala formation. Throughout the history of the dam,...
Design of Transient and Steady State Drain Spacing
Drain spacings calculated by steady state or transient equations can be made equal by adjusting the design water table height used in the equations. The adjustments are not constant and...
Influence of Irrigation on Subsurface Drainage
The influence flood irrigation has on drainage effluent in terms of discharge rates and water quality was analyzed at an artificially drained alfalfa field in Fallon, Nevada. Immediately...
Simulation of Runoff and Infiltration of Disturbed Land
Disturbances of land due to human and natural causes change the porosity and hydraulic conductivity of the soil. A simulation model of conjunctive surface-subsurface flows can be used...
ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...
A Monumental Task
The geotechnical consultants, structural engineer and contractor combined to overcome difficult soils, underground subway structures and buried utilities when building the foundations...
U.S. Navy Deployable Waterfront Facility
The U.S. Naval Civil Engineering Laboratory (NCEL) has been developing the concept of a Deployable Waterfront Facility (DWF) as part of its technology development programs for the enhancement...
Naval Homeport Facilities at Pensacola, Florida, and Mobile, Alabama
Presented herein are histories for the planning, design, and construction of the Navy's two newest homeport waterfront facilities in the Gulf of Mexico. Included are the waterfront facilities...
Draft Chapter 3?Planning and Design Guidelines for Small Craft Harbors?Inner Harbor Structures
The purpose of this paper is to present, in draft form, the third chapter of a technical report on the planning and design of small craft harbors being prepared by a special task force...
Alternative Methods of Drainage Management in San Joaquin Valley, California
The subsurface drainage and drainage-related problems in the San Joaquin Valley cost millions of dollars to the State and local economy every year. A number of actions have been proposed...
Ongoing Monitoring Results Pilot Stormwater Disposal Facilities, Pierce County, Washington
The three stormwater disposal facilities evaluated appeared to increase in pollutant removal effectiveness after approximately 4 to 5 months of operation. This may be due to the deposition...
Site Impact Traffic Assessment
Problems and Solutions
Transportation needs have traditionally derived from land use decisions. Site impact traffic analysis is a formalized process that attempts to quantify the need for transportation improvements...
Use of Manned Submersibles to Investigate Slumps in Deep Water Gulf of Mexico
The Johnson-Sea-Link manned submersible was used to investigate surface slumps in the deep water Gulf of Mexico. High quality and specifically placed seafloor cores, video tapes, 35 mm...
Old Problems and New Challenges in Marine Geotechnical Engineering
The discipline of marine geotechnical engineering originated nearly five decades ago, primarily as a result of the offshore oil and gas industry. As this industry moved into deeper waters,...
Norway's Olympic Cavern
A mountainous task had been undertaken by Norwegian firms in constructing the world's largest in-mountain colosseum for the 1994 Winter Olympic Games in Norway. The Norwegian...
