Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...
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...
Analysis of Exceptional Meteorological Conditions on July and August in Conakry
Conakry is a zone that receives more precipitation than other countries in West Africa. Sometimes the quantity is more than 4,000 mm per year. Strong rainfalls are observed between July...
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...
Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...
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...
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...
Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...
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...

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...
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,...
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...
Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...
