Storage Tanks: Going Above Ground
Until just a few years ago, the traditional replacement for a leaking underground storage tank was a new UST. But in September 1988, EPA finalized new regulations for UST systems containing...
Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...
An Experimental and Analytical Study of the Shoreline Response to Non-Parallel Breakwaters in Oblique Waves
REsults of an experimental and analysis study single breakwaters on oblique waves are presented. Three orientations of the breakwaters are studied, those being parallel to the shoreline,...
A Sonobuoy-Sized Expendable Air-Deployable Directional Wave Sensor
Obtaining wave information from small expendable air-deployable buoys is important for numerous military operations, civilian applications, and research purposes. Such buoys may be deployed...
Wave Runup on and Wave Reflection from Coastal Structures
Wave runup and wave reflection are two of the most important, easily quantifiable variables that influence the design of coastal structures. Unfortunately there are very few comprehensive...
Decay of Random Waves on Non-Monotonic Profiles
A model is presented to calculate the decay of random waves in the surf zone with special focus on non-monotonic profiles. A wave-by-wave approach is employed to derive a model that requires...
Experimental Study of Undertow and Turbulence Intensity Under Irregular Waves in the Surf Zone
Experiments are performed in a two-dimensional wave tank with a sloping beach. Irregular waves are generated and the water particle velocity is measured in the surf zone with a laser Doppler...
Modeling Bottom Friction in Wind-Wave Models
Effects of bottom friction in wind-wave models are investigated, with an emphasis on wave-induced bottom roughnesses (moveable-bed effects). A state-of-the-art bottom friction model is...
Estimating Laboratory Wave Reflection Using Laser Doppler
Estimates of irregular wave reflection in two-dimensional laboratory wave tanks are typically accomplished using an array of spatially separated wave gauges. This paper presents a frequency...
Breaking Wave Measurement by a Void Fraction Technique
Breaking of steep surface gravity waves in seas under moderate to strong wind forcing always involves the entrainment of air into the water column below the air-sea interface. As such,...
Bio-Remediation of Simulated Fire Training Facility
A leaking aviation fuel underground storage tank system utilized for fire fighting training at the Will Rogers World Airport was removed by Oklahoma City Department of airports personnel....
Optimization of Reservoir Releases to Control River Sedimentation Using Differential Dynamic Programming
A new methodology is developed to address sedimentation control in alluvial rivers downstream of reservoirs. An optimization model is posed as a discrete-time optimal control problem to...
The Application of Streamflow Duration Curves in Water Resources Engineering
Streamflow duration curves are a useful graphical and analytical tool for illustrating the relationship between the frequency and magnitude of daily streamflow. They are commonly used...
Prediction of Gravel Bedload with SAM
Bedload measurements for Little Beaver Creek in Colorado were used to test the sediment transport functions included in SAM. The test results showed that Toffaleti predicts total bedload...
Procedures for Evaluating the Effects of Sedimentation on Flood Hazards in Urbanized Areas in the Southwestern U.S.
Urbanization of watersheds in the arid Southwestern U.S. creates problems for resource agencies and design engineers. Traditional analytical techniques that are generally applicable to...
Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...
Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...
Performance of Oil Storage Tanks on Vibroflotation Improved Hydraulic Fill in the Port of Tampa, Florida
The paper describes a case history of design, construction and performance monitoring of two 80,000 barrel oil storage tank foundations 35 meters in diameter on a soft hydraulic fill soil...
Settlement Predictions Using Piezocone
Detailed data on settlement predictions and measured values are given for two water tanks and an area of fill constructed on a thick soft clay stratum that showed decreasing preconsolidation...
Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
