Real-Time Precipitation-Snowmelt Model for the Monongahela River Basin
The Pittsburgh District, U. S. Army Corps of Engineers, is responsible for operating two multipurpose reservoirs in the 7400 square mile Monongahela Basin, which is located in Pennsylvania,...

The Rx for Relief from Equipment Failure
A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data...

Central Arizona Project Startup
The Central Arizona Project is a water conveyance scheme, lifting and conveying Colorado River water from Lake Havasu on the Colorado River 190 miles to Phoenix and another 150 miles to...

Applied Hydro System Operations Models
The paper discusses computer simulation of system operations. Computer programs that simulate operations through future time periods on hourly, daily or monthly time periods are routinely...

Operations Models of the Columbia Reservoir System
Several of the computer models used in management of the basin's reservoir system are described. Among the models discussed are the Streamflow Synthesis and Reservoir Regulation...

California Water Project Operation
The California State Water Project (SWP) is operated and managed using state-of-the-art operations research and optimization techniques. Medium- and long-range studies for the operation...

Model to Maximize Releases for Supplemental Generation in a Pump-Storage System
An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage...

Plunge Pool Energy Dissipators for Some Dams in Taiwan, ROC
This paper presents a brief description of the characteristics of the plunge pool type energy dissipators, including design considerations, hydraulic model tests, as well as the results...

Air Slot in Tunnel Spillways of Feitsui Dam
The tunnel spillway of the Feitsui Reservoir Project near Taipei has a head drop of more than 110 m, and maximum discharge of 1,500 cms. For prevention of cavitation in the tunnel, an...

Modeling of the Undular Jump for White Water Bypass
Two of the authors have reported previously on the hazard that a conventional hydraulic jump with a uniform reverse surface roller presents to white water boaters. The intent is to create...

Scale Model Study Benefits Hydropower Project
The Jim Falls Project on the Chippewa River in Central Wisconsin deals with the replacement of an aged 11 MW run-of-river hydropower plant by a 48 MW peaking plant. A hydraulic model built...

Simplified Prediction of Storm Surge on an Open Coast Using a Microcomputer
Computer-generated wind fields have a flexibility that is not available with standard manual procedure; i. e. different illustrative concepts can be given a trial run at low cost. A spreadsheet...

Computational Enhancements to a Multidimensional Dynamic Programming Algorithm
This paper discusses ongoing work in investigating the vectorization potential (speed-up) of multidimensional dynamic programming computer codes on the Control Data Corporation (CDC) CYBER...

Sedimentation Processes in Hydrosystems, Numerical-Empirical Modeling
This paper presents the results of a newly developed computer simulation model for studying the sedimentation processes in a variety of hydrosystems. The most effective numerical methodology...

Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...

Design Storms for Urban Drainage
The characteristics of design storms for urban drainage are reviewed. There are indications that, under certain conditions, design storms produce runoff simulation results which are equivalent...

Characteristics of Intense Storms in Kansas
This paper examines point-rainfall characteristics of intense storms in Kansas. Hourly rainfall records were analyzed for 1006 intense storms selected from some 1800 station-years of data....

Use of Continuous Simulation Versus the Design Storm Concept for Water Quality
The validity of the design storm concept has been challenged by several investigators since the development of computer simulation models. Of particular interest are the studies that compare...

Outlet Structure Hydraulics
Current detention basin design procedure is to design the outlet structure for two or more return periods. This is sometimes done by combining weirs and/or orifices of various sizes and...

A Robustness Constraint for the Analysis of Uncertainty
A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs...
