Comparison of Some River Discharge Calculation Methods
To measure the discharge of a river, it is necessary to develop a stage-discharge curve based on water velocity at various cross sections of the river. This is the method which is used...

Flutter Derivatives from 14 Generic Deck Sections
The results of a series of wind-tunnel bridge-deck section-model experiments are discussed. Fourteen section models, seven with H-shaped cross-sections and seven with rectangular cross-sections,...

HEC-1 and HEC-2 Applications on the Microcomputer
The Hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles programs for MS/PC-DOS compatible microcomputers...

Overview of a Real-Time Flood Management Model
A flood management model was developed for the operation of the six reservoirs making up the Highland Lakes System on the Colorado River in Texas. The model allows simulation of over 700...

Effects of Lane Width Reduction on Safety and Flow
This research dealt with the issue of lane narrowing as an alternative to pavement widening in providing safety improvements on urban freeways. This study dealt with I-95 in Miami Florida...

Back on a Full Speed Track
A $30 million rehabilitation project is transforming a Massachusetts rail line that shows its age and poor maintenance history. Rehabilitating the line from Bristol County, Mass. to Hyannis...

Parameter Optimization of Dynamic Routing Models
The methodology utilizes approximate cross-sectional properties represented by separate power functions for channel and floodplain, and a very efficient optimization algorithm for determining...

The River Walks of San Antonio Move to Providence
At the historic heart of Providence, Rhode Island, three rivers divide the city into three areas. Nearly one mile of river corridors have been abused over the last century, resulting in...

Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...

Composite Columns—Design and Examples for Construction
The new German standard DIN 18806, part 1 gives the rules for the design of composite columns. The general method, taking into account all the inhomogeneties of the two materials steel...

Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...

BAKWATR (3)--Computation of Gradually Varied Flow
The BAKWATR computer program computes profiles of gradually varied flow in open channels of irregular shape using a microcomputer. Channel cross sections are defined by a series of points...

The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...

Computer Techniques for Acquisition and Reduction of Cross-Section Data
DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained...

Application of a Detachable Gondola Ropeway in an Urban Transport Environment: New Orleans, La.
The first United States application of the detachable, monocable, gondola ropeway system as an urban transportation system is presented. The system is the Mississippi Aerial River Transit...

Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...

Mississippi River Fairview Crossing Test
To improve estimates of shoaling rates in the crossings of a deep draft channel from New Orleans to Baton Rouge, a prototype test was conducted in Fairview Crossing at Mile 116 above Head...

Salmon River Ice Jams
The ice conditions on the river during the freeze-up period and the simple analytical model used to predict the advance of the ice cover leading edge are documented. Ice cover thicknesses...
