Seismic Large Amplitude Liquid Sloshing?Theory
The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing...
Buckling Criteria for Earthquake-Induced Overturning Stresses in Cylindrical Liquid Storage Tanks
Perhaps one of the most common forms of seismic damage to cylindrical liquid storage tanks made out of steel is buckling of the tank wall due to vertical overturning stresses. Buckling...
Big-Scaled Tilt Test on Uplifting Behavior of Oil Storage Tanks
The authors conducted a series of static tilt tests using a very big model with the full similitude in order to investigate the uplifting behavior of large-scaled tanks. The model was...
Static Tilt Analyses of Uplifting Cylindrical Tank
This paper describes the general method adopted for predicting the static tilt performance of cylindrical liquid storage tank that is free to uplift. In the analysis described here, the...
Decision Framework for Assessment of Leaking UST's
A computer-based environmental planning tool, designed to help mitigate the environmental problems associated with leaking underground storage tanks (UST) is presented in this article....
Design and Implementation of a Risk-Based Remedial Action Program for Underground Tank Removal at a Dioxin-Contaminated Site
The unknown or uncertain conditions often inherent in hazardous waste site remediation projects complicate the job of the responsible professional to adequately assess and manage associated...
An Approach for Groundwater Plume Delineation
Product releases from underground storage tanks are in many cases very localized (point-source) and occur rapidly. When all or part of the released product reaches groundwater in a homogenous...
Civil Engineering Guidelines for Planning and Designing Hydroelectric Developments
Augering Answers
Leaking storage tanks, a long time environmental problem, are now being addressed nationally with cleanup regulations. Clearly, inexpensive and quick remediations are needed. This article...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...
Underground Storage Tank Program and Its Implications
National concern over leaking underground tanks storing hazardous materials and wastes has resulted in the implementation of the 1984 Amendments of RCRA, which include the requirement...
Bacterial Fingerprinting to Trace Source of Coliform Bacteria During Artificial Recharge
This report describes the use of a bacterial 'fingerprint' technique to determine if treated effluent from infiltration beds was the source of coliform bacteria...
Regulations Target Underground Tanks
When Congress passed the Hazardous and Solid Waste Amendments of 1984, (RCRA), underground storage tanks were considered to be a major threat to the country's water supplies....
Techniques for Delineating Subsurface Organic Contamination: A Case Study
Selection of techniques to detect and map subsurface organic contamination depends on the type of source, contamination, and hydrogeologic setting. Ideally, an investigator, manager, or...
Environmental Impacts of Arctic Marine Transportation: Addressing the Issues through Research and the Provision of Advice
The prospect of numerous transits of the Canadian Northwest Passage and other northern waters by icebreaking tankers raises various environmental issues. This paper reviews the growth...
Concrete Armor Mats: Large-Scale Wave Tank Tests Wave Stability Tests
Concrete mats provide an alternative to the more conventional shoreline stabilization techniques. Material requirements are low, placement techniques are straightforward and they tend...
A Small Community's Response to Catastrophic Coastal Bluff Erosion
This paper describes the actions taken by a small unincorporated coastal community in Northern California during a series of catastrophic bluff erosional events, which occurred between...
