Hydraulics of Enlarging Cannonsville Reservoir
This paper describes the hydraulic studies performed for enlarging the Cannonsville Reservoir with a gate system which could raise the normal storage level without having an adverse effect...

A Probabilistic Method for Determination of the Required Capacity of Reservoirs
Evaluation of water supply potential of multi-purpose dams generally involves determination of the required capacity of reservoirs for new dams and analysis of safe yield or reliable yield...

Modeling Coal Pile Leachate - A Case Study
Ground water transport of coal leachate from an existing unlined coal storage pile was modeled using the USGS 'Computer Model of Two-Dimensional Solute Transport and Dispersion...

Multiple Parameter Rule Curve for Reservoir Operations
A procedure for deriving operations rules for water supply storage in a multipurpose reservoir, based on physical principles and data analysis, is described. This procedure has several...

Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...

A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...

Sedimentation Impacts on a Pumpback Storage Facility
Concern over future sedimentation impacts at a proposed pump storage hydroelectric facility at Lake Francis Case on the Missouri River led to use of a numerical model to analyze lake hydrodynamics....

Nonlinear Axisymmetric Uplift of Circular Plates
A formulation of a method of analysis of the nonlinear axisymmetric response of the bottom plate of a liquid storage tank under uplifting forces is presented. At first, the plate is assumed...

Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...

Top Projects of 1987
Five notable entries in the 1987 Outstanding Civil Engineering Achievement competition are summarized. The Keehi Interchange of the H-1 Freeway in Honolulu is only 1.9 miles long, but...

Detecting Underground Piping Leaks
Most leaks from underground liquid storage systems occur in the piping rather than the tank itself. The piping system is the most vulnerable component of the system, requiring great care...

Sewers Get a Breath of Fresh Air
Domestic sewage pump stations and treatment facilities have long been plagued by corrosion and odor problems caused by hydrogen sulfide. It is also extremely toxic. Sulfide production...

Use of Transport Models in Airport Access Analysis
This paper describes transportation models built by Wilbur Smith and Associates (WSA) as part of a study of Newark International Airport (NIA), conducted for the Port Authority of New...

Teleport: New Wave Engineering
Between $600 and $700 million will be spent on teleports now being planned in the U.S., presenting interesting challenges to civil engineers. Just as airports and seaports serve as collection...

A Comparative Study of Two Capture Chamber Geometries
Results of an experimental study of two capture chambers are presented. The capture chamber geometries are those that have been either used or recommended in conjunction with pneumatic...

Water Supply System Rehabilitation
This report was prepared to assist practicing engineers meet the challenge of rehabilitating old drinking water systems, many of which have been in existence for over 100 years and are...

Making Parking Pay
This paper analyzes the financing opportunities and options for providing new downtown parking garages. It identifies the present financial posture of municipal parking agencies, analyzes...

The Effects of Earthquakes on Power and Industrial Facilities and Implications for Nuclear Power Plant Design
Fifteen earthquakes, ranging from magnitude 5.2 to 8.4 on the Richter scale that have occurred in five countries since 1952, were studied. This report documents the performance of power...

Exhibits Under Fiberglass
The San Diego Convention Center, scheduled for completion in 1988, is located on 11 acres of downtown land only 150 ft from the bay. It will cost $130 million for total of 1.7 million...

Relicensing/Renewal and Coordinated Consultation
A project which has been constructed and operating for a number of years offers a substantial set of empirical data for assessing how - and by whom - the project should be continued in...
