A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...
Physical Model of Current-Induced Scour at Ventura Harbor
This paper describes a 1:25-scale movable-bed physical model study of scour resulting from longshore current passing through a narrow gap on the leeside of the detached breakwater at Ventura...
Montioring and Modeling of Tandem Breakwater System at Hammond, IN
A tandem breakwater system was constructed in 1989-90 to provide protection for a large marina at Hammond, IN, at the south end of Lake Michigan. A five year monitoring program (1993-98),...
Interface and Data Management for Large Scale Optimization Models
(No paper) This paper presents ideas regarding how different groups of data can be stored and utilized, especially in the context of water resource policy discussions involving different...
River Replication
In 1997 a U.S. patent was granted to the U.S. Army Corps of Engineers for a new applied engineering tool and methodology called micromodeling, which uses a small-scale physical model to...
Analyzing Drought with a Simplified Climate Model
A simplified climate model with combined atmospheric-hydrologic processes has been developed at the University of California Davis for the study of physical processes related to drought....
Flow through Vertical Barrier Screens?Numerical Model
A simple one-dimensional numerical model based on the energy equation is developed to predict the normal flow distribution through barrier screens composed of several vertical segments...
Physical Distribution System Models for Assessing the Impact of Water Quality on Regrowth and Corrosion
Over the past several years, there have been several new and proposed Safe Drinking Water Act (SDWA) regulations that will require many water utilities to modif treatment operations to...
Entrainment of Eggs and Larval Fish into Propeller Jets
Because larval fish have limited mobility and eggs have no mobility, both are susceptible to entrainment into the propeller jets of passing vessels. Entrainment subjects eggs and larvae,...
Hydraulic Model Study of the Prado Dam Spillway
The existing Prado Dam, located in the City of Corona, CA, is deficient in providing adequate flood protection to the Santa Ana River floodplain downstream of the dam. To provide adequate...
A Combined Physical and Mathematical Modeling Scheme for Kapichira Hydropower Project, Malawi
A physical model and a mathematical model were used to study the flow patterns in a reservoir having a complicated bathymetry. The physical model measurements were compared with the predictions...
Reducing Model Study Time and Improving Reliability
Historically, the majority of effort expended in computer modeling of physical systems has gone into the numerical algorithms used in the computer programs. Other aspects of modeling have...
Modeling Contaminated Sediments
Using a computer model to analyze and predict sediment transport only works when the analyst considers the model's limitations and the physical processes involved, and conducts...
Natural Decay Resistance of Glued-Laminated Beams
The natural decay resistance of untreated Douglas-fir heartwood specimens sampled from glued-laminated beams was evaluated using a modified agar plate test modeled after the European Standard...
Multi-mode Aerodynamic Analysis of Long-Span Bridges
Multi-mode responses to wind excitation have been estimated in the past by considering the response of each mode and then taking the root-sum-square for the total response. Other procedures,...
Comparison of Two different Models of a Shell Roof
The main purpose of this study is to compare a physical model of a shell roof with a theoretical model of the same shell roof in order to verify the reliability of the Homeostatic Model...
Modeling of Deep Water Outfall Plumes in the East Australian Coastal Ocean
The paper reports on the modeling study of deep water outfall plumes in the east Australian coastal ocean. The primary aims of the modeling were to provide estimates of plume condition...
Analysis of Prototype Long Period Waves for Los Angeles/Long Beach Harbor Resonance Studies
Long period wave data have been collected at an offshore wave gage and system harbor gages for over eight years in the Los Angeles/Long Beach Harbor region. These expansion of the harbors....
Physical Modelling of Multidirectional Waves
A sixty-segment wave generator has been used since 1985 at the Coastal Engineering Laboratory of the National Research Council (NRC) of Canada to generate multidirectional waves, and study...
A Physically Based Conceptual Model for Simulating Contaminant Levels in Subsurface Water
A conceptual physical model is developed to simulate solute transport and mixing in the vadose (unsaturated) and groundwater zones. The conceptual model couples lumped-parameters models...
