Physical Model Verification of a Coastal Discharge
A 1:75 scale physical model of a thermal discharge into a rocky, semi-enclosed bay was verified against extensive field data. The model accurately reproduced the prototype temperature...

The Great Lakes Large Basin Runoff Model
The Great Lakes Environmental Research Laboratory (GLERL) developed its Large Basin Runoff Model (LBRM) specifically for modeling runoff and moisture storages in the large river basins...

Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...

Modeling Support for Stormwater Management
An innovative 'digitization' procedure has been developed and successfully utilized to accurately and economically prepare and manage the extensive amount of...

Electrical Design of Small Hydro Plants
Major aspects of electrical design criteria for small hydro power plants used in co-generation schemes are: turbine control, generator and excitation equipment selection, protection relaying,...

Performance Consideration for Selecting a Static Excitation System
Many hydropower plants today are being upgraded with new static exciter/regulator systems to replace the old existing rotary exciters. One type of system is the semi-inverting system where...

Run-of-River Controller for Hydro Plants
New York State Electric and Gas Corporation has installed programmable run-of-river (ROR) controllers at five of their plants. Each of these plants has either two or three units with installed...

The Benefit/Cost Ratio of a Physical Model Study
The discussions of a physical model study often appear first in the Federal Energy Regulatory Commission ('FERC') consultation process and when appearing later...

Random Vibration of Mass-Loaded Rectangular Plates
The classical method of separation of variables in conjunction with the Green's function of the vibrating plate is used to obtain the solution of the free vibration problem...

Dynamic Response Moments of Random Parametered Structures with Random Excitation
First and second order statistical response moments are formulated for linear multi-degree of freedom dynamical systems having both random load and random structural characteristics. A...

Stochastic Response for Tertiary Systems
A modal superposition method is presented for obtaining the response of a single-degree-of-freedom tertiary subsystem mounted on a primary-secondary system. The method is direct in that...

Dynamic Response of Systems with Uncertain Properties
This paper addresses the methodology for determining the response of a structure modelled as single-degree-of-freedom system whose mass, damping and stiffness parameters are known only...

Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....

Advancements in Physical Modeling of Pump Intakes

Trace Toxic Metals Emissions from Hazardous Waste Incinerators
A physical model is proposed in order to explain the vaporization of metals during metallic waste incineration and is based on work performed to investigate inorganic emissions from coal...

Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...

Behavior of Sediment-Laden Plumes on Steep Slopes
The near field behavior of dense, sediment-laden flows on steep slopes was investigated as part of a study of mine tailings disposal. A literature review indicated that field and laboratory...

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...

Optimization, Simulation and Multiobjective Analysis of Operating Rules for Reservoir Systems
In this paper, three steps are proposed for establishing reservoir operating rules which can be used in real-time without flow forecasting. In the first step, optimization models are used...

Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
