SWRRB.80: A Basin Scale Model for Microcomputers
The SWRRB (Simulator for Water Resources on Rural Basins) model was developed by the USDA Agricultural Research Service to simulate the daily stream flow, and sediment loads from agricultural...
Data Acquisition and Control for Hydraulic Models
The Waterways Experiment Station is expanding the use of computer controlled data acquisition and control equipment on a variety of hydraulic models. These systems are presently being...
Recent Developments in Hydrologic Instrumentation
The availability of space-age materials and implementation of state-of-the-art electronics is making possible the recent developments of hydrologic instrumentation. Material developments...
A Microcomputer Dispersivity Evaluation Method for Thick Aquifers
The Littoral Environment Observation (LEO) program uses volunteer observers recruited to obtain daily visual observations of such coastal variables as breaker height, wave period, direction...
Littoral Environment Observation Program
This paper presents a method for determining the longitudinal, transverse, and vertical dispersivities of a thick aquifer for a free convection tracer test using only measurements from...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Automated People Movers?The Need for Flexibility and Clarity
The Airtrans System at Dallas/Ft. Worth Airport is the best example available of how an automated people mover (APM) might function in an urban setting. An examination of Airtrans shows...
Can We Save the Ogallala?
The useful life of the Ogallala Aquifer, which underlies seven western states, can be extended indefinitely through water conservation in the widest sense of the term. In addition to optimization...
Hazardous Waste Cleanup: The Preliminaries
Court-ordered negotiations rather than a trial took five years but led to a flexible plan for cleaning up an inactive hazardous waste disposal site in Niagara Falls, N.Y. Contamination...
Hydropower's Newest Generation
Higher energy prices and strong incentives from the federal government have caused hydropower developers to consider sites that just a few years ago were scoffed at as mere trickles. Intense...
Two Projects Became One
Nontraditional funding and a new law were required before two Cortez, Colo. projects could be combined. Building a new canal and enlarging and lining an existing one to move water in essentially...
Small Water Users�Planning Crisis
Planning to rehabilitate small water systems�both irrigation and municipal water supply�often is ignored. In contrast, planning for new construction and for operations/maintenance work...
Tension-Compression Test of a Concrete Specimen Via a Structure Damage Theory
The concrete sample is assumed to consist of a large number of aggregates and cement paste. Their material properties are assumed to be perfectly elastic. The effective elastic property...
Forecasting the Demand for Electricity: An Examination of Alternative Approaches
This paper examines several approaches to forecasting national-level electricity demand. The various approaches are briefly examined, and the strengths and weaknesses of each are discussed....
Energy Forecasting Techniques: An Overview
This paper provides an overview of the primary forecasting techniques employed by electric and natural gas utilities to predict energy consumption and demand. Although the techniques discussed...
The Role of Demand Forecasts in Pacific Northwest Power Planning
This paper has two primary objectives: to acquaint a general audience with the basic approaches used to forecast the demand for electricity, and to discuss the role of demand forecasts...
The Impact of Demand-Side Management on Load Growth: Some Tentative Results
Demand-Side Management (DSM) programs including load management, conservation and strategic load growth are being implemented by a very large number of utilities for the mutual benefit...
Solutions in the Pipeline
Water and sewer agencies across the country are beginning to feel more comfortable about pipeline rehabilitation. Where once replacement was the ony alternative considered for aged, clogged...
Private Funds, Public Projects
Tapping private sources for public services is not new, though the concept has advanced from traditional contracting for services, which has been around since pre-Revolutionary War days....
New Safety for Old Dams
Shortly after the Phase I inspection program conducted by the U.S. Army Corps of Engineers in 1978-81, the Pennsylvania legislature authorized $300 million for repair of dams, ports and...
