Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...
Modeling Unsteady Open-Channel Flows Having Longitudinally Varied Fluid Density
Unsteady flows in waterways with fluid density varying longitudinally can be described by various sets of partial differential equations, according to conditions of density variation....
Temporal Development of Local Scour at Bridge Piers
The temporal development of local scour depth at circular cylindrical bridge piers is considered. New data are presented and used to quantify the influence of flow duration on the depth...
Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...
Development of a Hydrologic Model with Both Spatially Distributed and Physically Based Capabilities
A distributed hydrologic model is developed at The Pennsylvania State University for use with rasterized data bases. The purpose of the Terrestrial Hydrologic Model or THM is to investigate...
Suspended-Solids Flux at a Shallow-Water Site in South San Francisco Bay, California
Time series measurements of current velocity and suspended solids-concentration (SSC) made during December 1993 and March 1994 at a shallow-water site in South San Francisco Bay were used...
A Finite Element Analysis of Mach Reflection by Using the Boussinesq Equation
The numerical analysis of Mach reflection, which is the reflection of an obliquely incident solitary wave by a vertical wail, is presented in this paper. For the mathematical model in...
Accuracy of a 3D Hydrodynamic Model Verification due to the Relative Magnitude of Forcing Functions
An investigation of relative magnitude of forcing functions in a 3D time-varying hydrodynamic model verification has been performed by identifying some extreme forcing events for an estuarine...
Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...
Two- and Three-Dimensional Hydrodynamic Modeling of the Salton Sea, California
The Salton Sea, the largest surface water body in California, faces a myriad of problems related to rapidly changing water levels, rising salinity, accelerated eutrophication, fish kills,...
Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...
Stochastic Determination of Wave Heights for Flood Control Channels
Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel....
Coastal Dynamics '95
Demands to both utilize and preserve the beaches of the world require improved understanding of the underlying dynamics of the coast, as well as better modeling capabilities. To these...
Let the Buyer (and Seller) Beware
A merger or acquisition shouldn't be a gamble, but many firms depend too much on good luck and good will. For long-term success, the best bet is a checklist for professional...
Wave Forces on Inclined and Vertical Wall Structures

Impact-Echo Strikes Home
Diagnosing flaws without destroying the structure is the first step to cost-effective repairs. Impact-echo is one of the more successful nondestructive evaluation (NDE) methods that have...
Here Comes the Sun
This article is an overview of recent developments in alternative and renewable energy technologies. The entire field is reviewed and four energy sources likely to impact short-term markets...
Static and Dynamic Properties of Gravelly Soils
The behavior of gravelly soils has been the focus of much research in recent years. Large-scale penetration and triaxial tests, shear-wave velocity measurements, insitu freezing and sampling,...
Deep and High in Hawaii
The First Hawaiian Center, headquarters of the First Hawaiian Bank, will be the tallest building in Hawaii when it is completed in 1996. The unusual design, by architects Cohn Pedersen...
Microtunneling Meets Mother Nature
The world's first ocean thermal energy plant is getting a double. Microtunneling the second ocean intake 80 ft under the Pacific Ocean is proving challenging, partly due to...
