Evapotranspiration Data Management in California
This paper will discuss components of the California Irrigation Management Information System (CIMIS). CIMIS is an automated agricultural weather network operated by the California Department...
A Markov Chain Approach for Analyzing Palmer Drought Index
Drought is conceived as a period of below normal precipitation or moisture deficiency that would affect the social and economic activities of a region. The Palmer Drought Index (PDI) is...
Targeting of AgI in a Utah Winter Orographic Storm
A cooperative research program among the Utah Division of Water Resources, the National Oceanic and Atmospheric Administration, and the Bureau of Reclamation has investigated targeting...
Results from a Long-Term Winter Cloud Seeding Program in Utah
An operational wintertime cloud seeding program has been conducted in portions of Utah since 1974. North American Weather Consultants (NAWC) has conducted this program for a consortium...
Cloud Seeding: The Engineering is Done, but What About Social Impacts?
As engineers, we tend to focus on the technical aspects of cloud seeding, and may neglect important social aspects or potential side effects. Often people in the target area are more concerned...
The Present Status of Precipitation Enhancement by Cloud Seeding
Atmospheric water in the form of precipitation, is one of the primary sources of fresh water in the world. However, a large amount of water present in clouds never gets transformed into...
Durability Failure of a Concrete Block Port Pavement
A concrete block port pavement began showing distress after 7.5 years of use. Initial repair attempts found extensive areas of deterioration. The concrete blocks were cracking, spalling,...
Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
Rehabilitation of Chloride Damaged Concrete
There are several methods of rehabilitating structural concrete that must deal with the presence of chlorides. It is critical that the rehabilitation designer recognize the abilities of...
Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...
Environment One: A Master Plan Study for a New Scientific Research Station at the Geographic South Pole
The existing research station at the geographic South Pole is approaching the end of its useful life. This master plan study focuses on determining the technical and functional requirements...
Cold Climate Building Research at Wasa Base, Antarctica
During the Antarctic summer season of 1988-89 a permanent Swedish research station was erected at Dronning Maud Land, Antarctica. The station, named Wasa, is situated on a nunatak. A corresponding...
Recommended Cold Regions Meteorological Instrumentation
For nearly 30 years, CRREL has studied environmental conditions in winter weather. These efforts have concentrated on providing field-measured meteorological data and historical climatological...
Effect of Camera Geometry on Thermographs for Pavement Crack Detection
The research focused on the effects of camera heights and tilt angles on the ability to detect cracks in thermographs obtained with an infrared camera. Results indicate that differences...
Utilization of Weather Radar for Hydrologic Forecasting
New technologies to collect, analyze, store, retrieve and display hydrologic data offer significant improvements to conventional methodologies used for predicting hydrologic events. Computer...
The State of Nevada Operational Seeding Program
Integration of the Nevada Operational Weather Modification Program into management of the region's water supply is a key element to meet the increasing demands placed on these...
Time-Domain Transmitting Boundary Condition in Fluid-Structure Interaction Studies
One of the major difficulties in the nonlinear analyses of fluid-structure interactions has been the lack of exact expressions for the transmitting boundary in the time domain. Researchers...
Monitoring Absolute Sea Level Change
Global-scale monitoring of sea level change is a key component of the U.S. Global Change Research Program. The NOAA Global Sea Level program incorporates state-of-the-art satellite and...
The Weathering of Spilled Crude Oil in Coastal Water Environment
A research project was conducted at the Technical Research Centre of Finland (VTT) in order to study the long-term behaviour of spilled crude oil in the brackish water under cold and icy...
NOAA CoastWatch: Imagery for Coastal Resource Management and Research
As part of the Coastal Ocean Program, NOAA CoastWatch is developing systems that will provide enchanced near real-time high resolution imagery from meteorological satellites; habitat change...
