Predictions of Shoaling Rates for a New Harbor in Puget Sound, Washington
Physical and numerical modeling methods were used to predict shoaling rates in the proposed Naval Station Puget Sound, Washington. A simple analytical model (SILTHAR), based on the premise...
Numerical Modeling of Estuarine Training Structure Effects on Navigation Channel Performance
A two-dimensional, vertically averaged, numerical modeling technique is presented to analyze estuarine training structure performance. The technique consists of using the US Army Corps...
Storm Surge Model Sensitivity in Estuarine Areas
Under the auspices of the National Flood Insurance Program (NFIP), a numerical study was undertaken to determine the sensitivity of predicted storm tide levels within an estuary to hurricane...
Modeling Applications in Coastal Engineering
This paper discusses physical and numerical models of coastal processes as applied to coastal and ocean engineering projects. Some of the concepts and principles of modelling are identified...
The Typical Engineering Properties of Fly Ash
Knowledge of key physical and engineering properties of coal fly ash is needed in the planning, design, and construction of both disposal and utilization projects. While considerable data...
Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....
Salinity Intrusion Predictions by Analytical Expressions
Salinity intrusion in estuaries has traditionally been predicted by use of physical models and more recently by numerical models. Analytic techniques have seen quite limited use because...
Advanced Concept for Generation of Waves in Hydraulic Models
This paper describes a new wavemaker for the generation of naturally occurring waves in physical models of coastal areas. Recent research incorporating directional aspects of monochromatic,...
Hydraulic Model Investigation of the North Diversion Structure, Albuquerque, New Mexico
The North Diversion Structure diverts storm runoff around Albuquerque, New Mexico. Observed flow conditions have caused concern about the capacity of the structure and the safety of a...
Physical Modeling to Study the Extent of Removal of an Existing Lock and Dam on the Mississippi River
Locks and Dam No. 26 is located on the Mississippi River approximately 202. 9 river miles above the mouth of the Ohio River. This paper will discuss the utilization of a physical model...
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...
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...
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...
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...
On Analysis of Dynamic Structure/Media Interaction
A version of the Global-Local Finite Element Method (GLFEM) is applied to the analysis of soil-structure interaction under steady-state excitation. The soil medium is considered to be...
Constrained Viscoelastic Layers for Passive Vibration Control of Structures
Infills with constrained viscoelastic layers for increasing the energy absorption capacity of structures are examined. The infills are expected to 'work' in the...
