Streamflow Prediction and Allocation Model in Texas
The State of Texas' Water Rights Adjudication Act of 1967 provided for the creation of regional watermasters to divide the water of state streams in accordance with the adjudicated...
Flownets by Computer Graphics
A new method of drawing flownets for determining seepage losses in earth dams is developed. The flow and equipotential lines are drawn by modifying W. Kinzelbagh's method....
A Two-Dimensional Model for Estimating Leachate Flow in Landfills
A numerical model has been developed to compute the leachate flow from solid waste landfills in an unsteady state condition. The two-dimensional moisture flow equation along with the boundary...
Numerical Model Study of Groundwater Movement in an Aquifer of Bangladesh
Annual groundwater level variation in the aquifer of the Mymensingh-Tangail area of Bangladesh was simulated by applying an implicit finite-difference model of groundwater flow. The groundwater...
Application of a Water Budget for Instream Flows
A portion of a water supply reservoir can be dedicated to supplying instream flows. This subreservoir is operated to provide instream fish habitat below the reservoir when releases to...
A Package for Travel Demand Forecasting on The Macintosh
This paper introduced a package which may be the first to be developed for travel demand forecasting on the Macintosh. Features of the package and its capabilities are demonstrated through...
A Microcomputer Package for Interrelating the Highway Capacity Manual and SOAP 84
There is some evidence that the SOAP program may replicate signalized intersection delay more realistically than the 1985 Highway Capacity Manual (HCM) operational procedure for signalized...
California DOT CADD
Starting in 1983 the California Department of Transportation (Caltrans) embarked on a project to incorporate current computer technology into the project development process. Today the...
Computer-Assisted Creativity for Traffic Problems
The main objectives of this paper are to describe a system for computer-assisted creativity, or innovation support, known as The Idea Machine (TIM), and to highlight two case study applications...
Traffic Simulation and its Graphic Presentations
A computer simulation program for traffic signal timing design was developed. The program can provide some appealing graphic presentations not only of input data but also of output results....
Arterial Traffic Flow in Construction Zones
Previously, NETSIM (NETwork SIMulation model) was the only available simulation model that could investigate a wide mix of traffic control and traffic management strategies for a network...
Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...
A 3D-Stereo Graphics Interface for Operational Great Lakes Forecasts
A system for real-time predictions of Great Lakes physics and transport characteristics is now being implemented. The full 3D nature of the predictions demands accurate, high speed computer...
Flow Separation of Currents in Shallow Water
Flow separation of currents in shallow coastal areas is investigated using a boundary layer model for two-dimensional (depth-averaged) tidal flow past an elliptic headland. If the shoaling...
Estuarine, Shelf, and Ocean Hydrodynamic Modelling Approaches
Estuarine, shelf, and ocean hydrodynamic modelling approaches are presented in order to explore the development of a coordinated set of models to describe the complex interactions between...
Calibration of a Transport Model Using Halocarbons
A field study was conducted during April 1987 in which the concentrations of volatile halocarbon tracers, discharged from two existing outfalls, were measured throughout Boston Harbor...
Flexible Pipe Design Revisited
An overwhelming soil factor in the Iowa formula and random deformations at installation affords soil a prominent role in flexible pipe; this, together with a maximal deflection rule make...
A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...
Climate Change and Resulting Hydrologic Response: Illinois River Basin
In the last 20 years, the northern half of the Illinois River basin has been experiencing a wetter and cooler climate. This climate change has significantly increased Illinois River flows...
Finite Element Analysis of Hillslope Variations in Surface Runoff
Watershed management decisions are aided through an accurate understanding of hydrologic processes. The finite element method applied to surface runoff with spatially variable hydraulic...
