Using Weighing Lysimeters to Develop Evapotranspiration Crop Coefficients
Weighing lysimeters provide an accurate means of measuring evapotranspiration (ET), the evaporative loss of water from growing crops. Two weighing lysimeters were installed at a research...
Geochemical Mass-Balance in a Small Forested Watershed in Southwestern Pennsylvania
An intensive hydrologic investigation of the North Fork Bens Creek Watershed on Laurel Hill in southwestern Pennsylvania was made during 1984-85. Precipitation was sampled weekly, and...
Erosion Potential of Pacific Basin Precipitation
Average annual erosivity (EI) values were developed using 20 years of hourly precipitation data from weather stations located on each of 10 Pacific Basin islands. Average annual erosivity...
Discharge Forecast of Underground Tunnel System
An underground tunnel system can be discribed with linear system theory and its mathematical model can be made up according to its recharge and discharge conditions. But, because of so...
Forecasting Irrigation Water Supply Using a Computer Model and Remotely Sensed Snow Cover
Improved streamflow forecasting in the Sevier River Basin is one objective of the Sevier River Water Management Study. Short-term forecasts are needed for optimum operations of irrigation...
A Modular Visual Interface for Computational Fluids Forecasting
A forecasting system is under development for predicting the three-dimensional physical features (e.g. velocity, temperature etc.) of large water bodies. Visualization and interface development...
Where Does Rock Begin Beneath Philadelphia?
Philadelphia provides an excellent example of the engineering problems associated with the interpretation of saprolite/weathered rock/sound rock profiles. The bedrock beneath the city...
A Practical Model for Forecasting Water Supply Functions at Time of the Earthquake
This study aims to construct a practical forecasting model for the seismic damage restoration of city water supply functions by using experts empirical knowledge as well as the functional...
Calibration of High Frequency Pollen Sequences and Tree-Ring Records
Two radiocarbon dated paleoenvironmental records from southern Nevada are being examined with the possibility of correlating high-frequency pollen samples with nearby long-term tree-ring...
Environments of the Last 50,000 Years in the Vicinity of Yucca Mountain, Central-Southern Nevada
Located within the southern hydrographic Great Basin, the Nevada Test Site lies astride the transition between the Mojave Desert to the south and the Great Basin Desert to the north. Fossil...
The Multi-Watfore Method: A Water Demand Forecasting System
The multi-Watfore method, which combines the cascade model and a first order analysis of uncertainty, is a system of practical steps to develop models of water demand while generating...
Optimal Real-Time Operation of Te-Chi Reservoir
An optimization model for the 10-day operation of Te-Chi Reservoir in central Taiwan is developed. The inflow to the reservoir is forecasted by an ARX model with a Kalman Filter updating...
Application of Remote Sensing to Flood Forecasting
Forecasting flood flows caused by severe rainfall events relies heavily on a knowledge of the surface characteristics of a watershed and precipitation inputs. This information can be obtained...
Economic Benefits of a Flood Warning System?The Ventura County, California Experience
Since the spring of 1979, Ventura County has been receiving the benefits of a growing Flood Warning System (FWS). Beginning with six self-reporting raingages, two untested flow models,...
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...
Evaluation of Microcomputer Traffic Forecasting Models: The Michigan Experience
The paper describes results of the needs assessment for modelling software of Michigan's thirteen '3C' areas, criteria used to compare software capabilities...
A Future for UTPS on Microcomputers
The software and hardware support for Micro-UTPS is in a state of transition. IBM's development of the PS/370 gives mainframe power and performance to microcomputers and Micro-UTPS....
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...
Microcomputer Assisted Transportation Impacts Analysis: Hudson River Waterfront Development
Across the Hudson River from Manhattan, major office and residential developments are occurring on large tracts of former railroad and shipping properties in New Jersey. Much of this development...
Incorporating Risk Analysis Into Spreadsheet Forecasts
The risk analysis technique presented overcomes the difficulties of sensitivity analysis by entering key input variables as probability distributions, rather than as discreet values. Using...
