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...
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...
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...
Precipitation Simulation Model for Mountainous Areas
This study investigated the use of the Markov chain-mixed exponential (MCME) model as a means of obtaining synthetic daily precipitation amounts at a site, based on knowledge of the mean...
Remotely Sensed Input Data for Real-Time Flood Forecasting
The WATFLOOD flood forecasting system has been developed to use a variety of remotely sensed data, namely weather radar for precipitation, Landsat MSS imagery for land cover classification,...
Weathering of Constituents at Land Treatment Sites
The objectives of this research were to: 1) determine the leachability of metals and organics from soils at hazardous waste land treatment sites; 2) evaluate the mobility of hazardous...
Advisory System for South Florida Water Management
A comprehensive, real-time advisory system was developed for the operation of water control facilities within the South Florida Water Management District. The Operations Assistant and...
Development of the Hydrodata CD-ROM Data Storage System
To store and retrieve data from two of the USGS WATSTORE databases - the daily and peak values files - and the Summary of the Day file from the National Climatic Data Center, the authors...
Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...
Tapping A Glacier
The Eklutna water project receives a 1988 Outstanding Civil Engineering Award of merit. The project�a 30 mile pipeline and treatment plant that brings glacial runoff from Eklutna lake...
Issues of Detectability of Climate Change Impacts on the Runoff of a Southeastern River Basin
Can we detect and predict changes in hydrology caused by climate changes? Assuming credible predictions of climate change, can we predict corresponding hydrologic effects? Are uncertainties...
Simulation of Precipitation by Weather-Type Analysis
A new approach that uses weather-type analysis as a basis for stochastic precipitation modeling was developed and tested for Philadelphia, Pennsylvania. The weather types permit the identification...
New Clues to PMP
Great changes have occurred in meterology in the last two decades. Formerly, weather data were available for forecasting and climatological analyses only at points - at weather stations....
Rx for Dam Repair
Bernard asserts the growing importance of maintenance to extend the service life of dams as more and more of them reach or exceed their design lives. He describes renovations to Easton...
Foundation Treatment of Karstic Features Under TVA Dams
TVA has constructed many of its dams on limestone foundations. Some of these foundations have been highly weathered and required special treatment not only to ensure strength but to develop...
Clogging Study of Geotextile with Weathered Mudstone
This paper focuses on the combined use of fly ash and geotextiles as a solution for the typical engineering problem of weathered mudstone slopes encountered in Taiwan. In situ collapsed...
Reported Results from 600 Cloud Seeding Projects
The authors conclude that cloud seeding is an effective way of increasing precipitation when applied to the appropriate clouds and climate. Reported results from research projects show...
Colorado River Municipal Water District Weather Modification Program 1971-1986
The Colorado River Municipal Water District (CRMWD) has sponsored a rain enhancement program on summertime convective clouds in West Texas since 1971. Silver iodide is used for cloud base...
