Comparing Bowen Ratio-Energy Balance Systems for Measuring ET
Two Bowen ratio-energy balance (BREB) systems for measuring evapotranspiration (ET) under wet and dry conditions were compared. The study sites were an irrigated grass sod near Kimberly,...
Siting Agricultural Weather Stations
Studies were conducted in Arizona and Washington to investigate how the surrounding fetch affects data collected by agricultural weather stations (AWS). AWS surrounded by extensive areas...
The Utah Climate Center Weather Data Network
The Utah Climate Center weather data network includes 52 sophisticated, automated weather stations. Weather parameters are monitored in real-time and hourly summarized data are gathered,...
Nongrowing Season ET from Irrigated Fields
The evaporative loss of water from agricultural fields during the nongrowing season is an important component of the annual water balance of irrigated lands. This study was conducted to...
Updating Utah's Crop Water Use Estimates
Crop water use was estimated at National Weather Service stations throughout Utah for the 1961-1990 normal period. Daily weather data (air temperature, solar radiation, humidity, wind...
Revision of Oregon Crop Water Use and Irrigation Requirements
A project to revise the crop water use estimates and irrigation requirements for the state at Oregon is described. The FAO modified Blaney-Criddle method was applied in this project since...
Streamflow Depletions and Water Transfers in Idaho
In the state of Idaho, streamflow depletions are quantified utilizing parameters of rate of flow, total volume diverted, and volume consumptively used. This paper summarizes the engineering...
Streamflow Depletions for Water Transfers in Utah
All inter- or intra-state transfers of Utah water rights must be accomplished by application and receive the approval of the Utah State Engineer. This paper summarizes the engineering...
Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...
Streamflow Depletions Resulting from Ground Water Transfers
An application to move the point of diversion of a quasi-municipal ground water right from about 4.8 km to a second well about 0.3 km from a river channel was made in the Reno/Sparks,...
Hydrological Impacts of a California Water Transfer
Conaway Ranch, located in Yolo County, California, transferred water to the California Emergency Drought Water Bank (Water Bank) in 1991 and 1992. Water for these transfers was generated...
Water Transfer: Applicants and Objectors Analyses
Two different analyses of the historical on-farm consumptive use and return flows of agricultural water rights in Northern Colorado are discussed. The City of Thornton plans the transfer...
Soil Moisture Monitoring Using a Portable Capacitance Probe
Accurate monitoring of soil moisture has long been in integral part of a successful agricultural management system. Water has increasingly become a valuable and much sought after natural...
Water Penetration Manual for California Soils
Slow water penetration in irrigated soils is a complex problem of major importance in California's $18 billion agricultural industry. The Kearney Foundation of Soil Science chose to work...
Multiquadrics in Engineering Modeling
The theory of multiquadrics (MQ) is advancing rapidly and it is usable today. When appropriate MQ can accurately interpolate for unknown values with less computational cost than Kriging....
Evapotranspiration of Dry Beans with Drip Irrigation
Information about the effect of irrigation on dry bean production in the Southwestern Colorado is very limited. The primary objective of this study is to establish a crop water use (ET)...
Effect of Choptank Watershed Drainage Project on Stream Temperatures
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A conducted a stream study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of channel construction...
California Water Issues?Bay-Delta Hearings?Impacts on State Water Project
The State Water Resources Control Board's impending Decision 1630 is described along with its potentially substantial impacts on California's water supplies. Department of Water Resources...
Establishing a Drought Reserve Policy for the Monterey Peninsula Water Management District
The Monterey Peninsula Water Management District was created by the California Legislature in 1977 for the purpose of developing an integrated management program for all of the water resources...
Regulatory Constraints on Vegetation Control in Channels, A Case Study of the Santa Ynez River, Santa Barbara County, California
