Using an Index Stream to Make Instream Flow Decisions
The paper discusses development of an Integrated Operating Plan (IOP) that uses an unregulated (natural) stream in the upper Cedar basin as an index of overall hydrologic status of the...
Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...
Modeling Groundwater Flow in San Joaquin Valley
Water supply, reallocation and conjunctive use options, within the San Joaquin and Tulare basins of the Central Valley of California, are being considered by Federal and State Planning...
Groundwater Modeling of the Tustin/Irvine Basin
This paper describes the results of groundwater modeling in the Tustin/Irvine basin situated in the southeastern portion of the Tustin plain, which is the the southern extension of the...
Spatial Averaging of Statistically Anisotropic Point Conductivities
This paper presents a new technique to compute the mean, variogram and cross-variograms of the components of block conductivity tensors given the statistical distribution of point conductivities....
Instream Habitat Considering Hydro-Peaking
Hydroelectric projects with storage have the characteristic of being able to generate electricity with short notice and to stop generating electricity with equally short notice. This peaking...
Identification of Aquifer Parameters in Confined Groundwater Flow
The logarithm of the aquifer properties, log transmissivity (log T) and log storativity (log S), are regarded as realizations of stochastic processes whose estimates are required. The...
Causes and Possible Control Measures of Flood in Bangladesh
Intensity and frequency of occurrence of devastating floods in Bangladesh have increased significantly over the past two decades. Large scale deforestation in the upstream reaches of Ganges,...
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...
