Section Seven—Case Histories in Seasonal Frost Areas

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...

Oklahoma Southwest Cooperative Program—An Update
In an effort to meet present and future regional water needs, the Oklahoma Water Resources Board and the Texas Water Commission (TWC), the Oklahoma effort has addressed three basic components:...

AgriMet—ET Phones Home—(Adaptation of Satellite Telemetry for Crop Water Use Modeling in the Pacific Northwest)
The development of a regional automatic agricultural weather station network in the Pacific Northwest (AgriMet) is enabling the site-specific calculation of evapotranspiration (ET) through...

Use of the Penman Equation in Inter-Mountain Valleys
H.L. Penman equation as well as the J.L. Monteith version of this equation were compared under the advective conditions of the Grand Valley of Colorado. The wind function in the general...

Near-Real Time Weather Information for Irrigation Management in Arizona
The Arizona Meteorological Network (AZMET) is a near-real time ag-weather information system for Arizona. A single personal computer running inexpensive bulletin board software controls...

Crop Irrigation Requirement Model for Utah
Crop irrigation requirements vary greatly across Utah's wide range of climatic conditions. About 40 electronic weather stations have been established in areas representing...

Collection, Quality Control and Dissemination of Weather Data for Irrigation and Other Operations in an Automated Setting
High technology has made it possible to completely automate the collection of weather data. Care must be taken in designing the automated system to generalize the software components thereby...

Irrigation Scheduling Using Voice Synthesis, the Next Logical Step
An irrigation management program sponsored by the Raft River Electric Cooperative in Malta, Idaho, provided directly measured soil moisture data to selected irrigators each week during...

The North Dakota Atmospheric Resource Program
For over a third of a century regions of North Dakota have conducted cloud seeding operations aimed at hail damage mitigation or rainfall enhancement. Cloud modification has become an...

Weathering Steel: Industry's Stepchild
Improper location and poor detailing are two reasons why some weathering steel bridges are not living up to their early promise. That was the consensus reached during a July 1988 forum...

Design of Drilled Piers in the Atlantic Piedmont
The philosophy and methods of drilled pier foundation design in the Atlantic Piedmont are described. Consideration is also given to the unique characteristics of decomposed metamorphic...

Foundations and Excavations in Decomposed Rock of the Piedmont Province
The five papers in this volume deal with foundations and excavations in the Piedmont Province of the USA. This is a region underlain by very old metamorphic rocks that are overlain by...

Remote Sensing of Estuarine Dynamics Using the NOAA Polar-Orbiting Weather Satellites
The Advanced Very High Resolution Radiometer (AVHRR) onboard the NOAA-n series polar-orbiting weather satellites collects data that can be used to estimate surface water temperature and...

Crop Production Models in Water Management
A weather generating model called WMAKER is introduced. The model generates daily climatic data based on the mean monthly values of temperature, precipitation, number of rainy days and...

Calibration of an Evapotranspiration Model Using Eddy Correlation Methods
An evapotranspiration (ET) prediction model was developed by calibrating the H. L. Penman equation for an alfalfa reference crop in the southwestern Oklahoma region. Evaporative flux for...

Transfer of Weather Modification Technology to Users
The Task Committee on Utilization of Weather Modification Technology was formed in October 1984 with the stated purpose 'To facilitate the transfer of information concerning...

Weather Modification Regulation for the Twenty-First Century
Those areas in which weather modification law is being altered to fit the twenty-first century are: 1. De-regulation. Regulation of weather modification through mandating professional...

T Measurements for Irrigation of Sweet Corn
Commonly used scheduling methods are based on a water balance approach where evapotranspiration (ET) must be either estimated from climatic data or by soil water depletion measurements....

Crop Yield Models Adapted to Irrigation Scheduling Programs
A crop yield model (CRPSM) was adapted to match the data obtained with typical irrigation scheduling programs. Daily soil water content was calculated from weather data, crop growth stage...
