Monte Carlo Approach to Spillway Design Floods
This paper shows the use of a daily stochastic streamflow model for the calculation of the hydrograph for spillway design. Most of the literature related to the topic deals with the problem...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...

Building High Tech in China
The tallest steel structure in the People's Republic of China is being built by an international complement of designers, suppliers, vendors and contractors. It is the 42...

A Microcomputer Storm Sewer Program for Highway Drainage Design
This paper presents results and findings of an ongoing research project on highway drainage sponsored by the Federal Highway Administration through the Virginia Transportation Research...

Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering, August, 1987, Williamsburg, Va. The objective of this conference was to provide a forum...

Engineering Hydrology
The Surface Water Hydrology Committee, ASCE Hydraulics Division, sponsored this first Symposium on Engineering Hydrology. The Symposium was held jointly with the ASCE National Conference...

Harbor Revived
In Racine, Wis., officials' plans to turn a defunct commercial harbor into a recreational boaters' paradise have signaled an economic turn-around for a depressed...

Fail Safe Management
Engineers are increasingly embroiled in cases where failure is defined as improper administration or management of a procedure instead of the collapse of a structure or the failure of...

Studies With, and Testing of the McCormick Pneumatic Wave Energy Turbine With Some Comments on PWECS Systems
Work done in developing concepts for pneumatic wave energy conversion based on theoretical analyses of the hydrodynamic, pneumatic, and mechanical systems with some estimates of performance...

Taking the Loss Out of Risk
Since Superfund was authorized in 1981 and 22,000 hazardous waste sites put on notice, funds for remedial action have peaked with $20 billion annual clean-up budgets projected. But to...

Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...

Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...

Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....

Small Scale and Low Head Hydro Development in Canada: An Overview of Federal Activities and Policy
Through research and development, new small turbines have been tested and a Darrieus type vertical axis hydraulic turbine (VAHT) has been developed and field tested. Manuals for hydrologic...

Development of the Owyhee Dam Hydroelectric Project
The Owyhee Project Power Committee and Owyhee Irrigation District are developing the Owyhee Dam Power Plant, currently under construction in eastern Oregon. The power plant is being constructed...

Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...

Mini Hydro at the Hackett Mills Project
The project includes rehabilitation of a timber crib dam and the first use of a Right Angle Drive turbine in the United States to generate power from the 16 feet of head available at the...

The Ruedi Project?A Case Study
Ruedi Dam is a 285' high earthfill structure constructed in 1968 by the Bureau of Reclamation as part of the Fryingpan-Arkansas Transmountain Diversion Project. In November...

Planning & Execution for Rehabilitation of Large Francis Turbine/Generator Units
This paper highlights some of the constraints in planning and execution of rehabilitation work which must be carried out within an extremely tight schedule, dictated by hydrological considerations...
