Utilization of Geographic Information Systems Technology in the Assessment of Regional Ground-Water Quality
The U. S. Geological Survey (USGS) in cooperation with the U. S. Environmental Protection Agency Office of Pesticide Programs and several State agencies in Oregon has prepared a digital...

Managing Water Resources Using Geographic Information Systems as a Tool
The Oregon Water Resources Department is designing and using a geographic information system (GIS) to manage water rights. The system allows automation of many tasks including: production...

Water Resources Planning Information Available from CFS
Public officials, natural resource management agencies, research scientists, reservoir operators, and agricultural interests in the western U. S. now have access to several major automated...

Coastal Zone '87
Coastal Zone '87 is the fifth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

The Applicability of Satellite Altimetry Data to Tidal Models
Different tidal regimes require different data assimilation schemes. In all cases, however, it is better to perform a separate tidal solution before assimilation. For proper assimilation...

Spatial Attenuation of Major Pennsylvania Storms
To utilize point estimates for more expansive areas, reduction factors are necessary to account for the attenuation of storm magnitude with increasing area. The spatial attenuation of...

Experiences of the U.S. Army Engineer District, Pittsburgh in Collecting Real-Time Water Control Data
As a result of an ever increasing need to optimize water use, 'Reservoir Regulation' has evolved into what is now known as 'Water Control Management'. In addition to the flood control...

The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...

Denver Area Real Time System
This paper presents a discussion of the development of the Denver Area Real Time System which will be used to regulate the Denver reservoir system on a real-time basis. Its main components...

Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...

Geographic Estimation of Runoff-Model Parameters
The U. S. Geological Survey is developing techniques to estimate and evaluate unit-hydrograph and loss-rate parameter values for rainfall-runoff models using Geographic Information System...

A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...

Modified CIMIS Irrigation Scheduling Program
CIMIS, California Irrigation Management Information System, is a program that collects weather data around the state to assist irrigators in planning and scheduling their irrigations....

Integrated Information System for Traffic Control Device Management
Traffic engineers and planners have the day-to-day responsibility to maintain the safety and operational efficiency of streets and highways in their jurisdictions. Managing traffic control...

ITEEMS: Reducing Mainframe Systems to Micro-scale
The Integrated Traffic Engineering and Enforcement Monitoring System (ITEEMS) is a microcomputer-based system which has an on-line display and analysis of accident records by street intersection,...

NEDS?Network Editing and Display for TRANPLAN
This paper explores some of the current and possible future applications of interactive graphics packages to the tasks of analyzing and planning transportation systems. The source of the...

Mapping New York City from the Shelf
Data processing and management information systems are a cornerstone of the operating environment and capabilities of New York City (NYC) agencies. One of the functions that make NYC's...

Computerization of Transit Performance Evaluatio
The Virginia Transit Performance Evaluation Package (VATPEP) has reduced the state's effort in processing information for its annual report on public transportation from over...

Human Factors in a Bus Route Monitoring System
In 1984 the Maryland Mass Transit Administration began a systemwide route monitoring effort. Data collection was accomplished principally by on-board checkers using laptop Epson microcomputers...

Using Microcomputers for Maintenance Management in a Small Transit Agency
