Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....
Instrumentation Needs and Possibilities: A Dialogue Between Suppliers and Users
The present symposium includes a panel discussion to address and illuminate needs and possibilities in hydraulic instrumentation. The panel discussion is organized with the intent of promoting...
Practical Method for Scour Prediction at Bridge Piers
A practical method is presented for prediction of local scour at bridge piers which is based on a comparison of many well known equations and supported by field data. This equation includes...
Practical Method for Calculating Contraction Scour
Total scour at bridge crossing waterways consists of long-term aggradation or degradation of the streambed, contraction scour and local scour at the piers and abutments. This paper will...
Effects of Flow Duration on Local Scour at Bridge Piers in New York
The relation of local scour to the duration of high flows and other hydraulic properties is being studied at 31 bridge sites in New York State. Clear-water scour is common at most of the...
Kent, Edward
In order to perform conservative scour analyses for coastal bridge sites it is necessary to develop realistic hydraulic simulations which provide worst case estimates of depth and velocity....
On the Erodibility of Rock and Other Earth Materials
An outline of a new method to determine the erodibility of rock and other earth and engineered earth material is presented. The method quantifies the relative capacity of the boundary...
GLFSVIEW - GLFS Product Viewing Application
GLFSVIEW is a menu-driven Visual Basic application running under MicroSoft Windows. This application allows quick downloading, browsing, printing and display of two-dimensional data maps...
Short-Term Forecasts for Lake Erie
Short-term forecasts for Lake Erie were generated by coupling a mesoscale atmospheric prediction system with a lake forecast system. The modeling systems used were The Pennsylvania State...
Nonlinearity and Free-Surface Flow
The Dupuit-Forchheimer (D-F) assumption is commonly considered a viable design criterion for water resources projects and, consequently, Darcy law is used to determine the locus of free...
Verification of Lake Superior Outflow Equations
The outflow from Lake Superior, the largest volume freshwater lake in the world, is regulated by the International Lake Superior Board of Control in accordance with the Treaty of 1909...
Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...
Force and Pressure Measurements in Spillway Plunge Pools
Plunge pools are often used to dissipate energy from high head spillways with flip bucket terminal structures. Conventional design of plunge pools has been based on a program of mobile...
Verification of a Three-Dimensional Model of Delaware Bay
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
1993 Mississippi Record Stages and Levee Failures
Record-setting stages, flooding duration, and multiple levee failures are distinguishing features of the Mississippi River 1993 flood. The peak stages reached at stations along the Illinois...
Historical Trends in Flood Discharges on the Upper Mississippi River
Long-term streamgage records in the Upper Mississippi River Basin were analyzed using a Kendall Tau-b analysis to determine trends in flooding and average flows. Over the 130 years of...
The Summer of 1993 Floods Lower Missouri River
Throughout the State of Missouri from November 1992 through July 1993, precipitation set new records, in some cases ranging as high as 200 - 400 percent of normal rain fall. Missouri precipitation...
Problems with Indirect Determinations of Peak Streamflows in Steep, Desert Stream Channels
Many peak streamflow values used in flood analyses for desert areas are derived using the Manning equation. Data used in the equation are collected after the flow has subsided, and peak...
Analysis of the Causes and Triggering Events of Disastrous Torrent Flood
A disastrous torrent flood on the Vlasina River of 26 June 1988 was of unprecedented intensity in Yugoslavia. The catchment area affected by the catastrophe covered more than 1000 km2...
