Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
Estimating Low-Flow Frequencies of Ungaged Streams in New England
Equations to estimate low flows were developed using multiple-regression analysis with a sample of 48 river basins, which were selected from the U. S. Geological Survey's...
Application of the New SCS Time of Concentration Method
The second edition of the Soil Conservation Service (SCS) TR-55, published in June 1986, introduces a new method for calculating the time of concentration for storm runoff flowing through...
Some New Snyder Type Coefficients for Small Watersheds
Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq...
Changing Hydrology - The Middle Mississippi River
Observed daily flow and stage at major stream gages on the middle Mississippi River are numerically and graphically analyzed to quantify and illustrate the magnitude and seasonality of...
The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...
A New Method for Synthesizing a Six Hour Unit Hydrograph
A new methodology was devised that would use readily available basin physical parameters for the determination of unit graphs in undeveloped and ungaged areas. Rather than using small...
Measuring the Spatial Characteristics of Unsteady Pressures
This paper has reviewed current methods of determining spatially-averaged time-varying wind loads on wind tunnel building models. Some of the possibilities opened by simultaneous multi-channel...
Coastal Hydrodynamics
This book includes papers presented at the ASCE Specialty Conference on Coastal Hydrodynamics Conference, at the University of Delaware, June 28-July 1, 1987. The papers review the state...
Rescuing the Everglades
After a century of trying to control Florida's Everglades, water management officials have decided that cooperating with nature is better. A new strategy known as the Rainfall...
A Burning Wasteland Reclaimed
Until recently the PJP Landfill exemplified what can happen when uncontrolled and illegal dumping goes on for many years. Now it is an example of what innovation and imagination can do...
Considerations in Applying the 1985 HCM Procedures
The paper examines the impact of critical assumptions in the 1985 Highway Capacity Manual (HCM) procedures on the resulting measures of effectiveness -- volume/capacity ratio, delay, and...
Modeling Permissive Movements in TRANSYT-7F
Traffic Network Study Tool (TRANSYT-7F) is one of the most widely used traffic flow analysis and traffic signal timing optimization models in the United States and elsewhere. Through 'Release...
Conversion of the MIDAS Accident Analysis Model
The MIDAS (Michigan Dimensional Accident Surveillance) System has been developed to provide accident analysis capability. A microcomputer version of MIDAS is being developed to make the...
Teacher Friendly Transportation Programs
This contribution describes a set of computer programs that has mainly been developed to demonstrate operating and possibilities of mainframe programs during lectures. The program set...
Expert Systems for Traffic Signal Control
The level of service achieved by a pretimed signal timing control strategy implemented at an isolated intersection incurring saturated and over-saturated demand varies with actual traffic...
Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....
FEM-Flow Analysis in Hydraulic Turbomachinery Runners
Finite element calculations of the flow through distributor and runner of hydraulic turbomachines are presented. The method is quasi-3D and inviscid, but the deviations from a potential...
Uncertainty Analysis of Field Turbine Performance Measurements
This paper presents comprehensive uncertainty analyses of two different flow measurement methods for field tests on turbines. The 'water to wire' efficiency was...
A Review of the Cross-Flow Turbine
The historical development of the cross-flow turbine is briefly presented together with a summary of the well-documented one-dimensional theory. Two-dimensional aspects of runner design...
