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 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...
Evaluating the Facts in Water Right Changes
Under the western system of appropriation water rights may be separated from the land and the time, type and place of use changed. Such changes are governed by the principle that there...
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...
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...
Availability Analysis of Irrigation Systems for Improved Management
Availability of an irrigation system is defined as the ratio of time of successful system operation to total desired operation time. Operation is successful when the flow rate of water...
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...
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)...
Computing in Civil and Building Engineering
This proceeding consists of papers presented at the Fifth International Conference on Computing in Civil and Building Engineering held in Anaheim, California, June 7-9, 1993. The proceedings...
Getting Along: The Geotech and the CM
The opinions of geotechnical engineers are usually respected within a consulting firm, but when such a specialist gets out in the field, he or she is seen as merely part of the backup...
Computer Scheduling and Construction Specs
As recently as the early 1980s, employing computers in critical path method (CPM) scheduling was a formidable decision demanding considerable commitment of time and resources by management....
Lead is a Four-Letter Word
New regulations and strict enforcement make it difficult and expensive to remove lead-laden coatings from steel structures. Lead-based primers and paints are not considered hazardous as...
Local Water, Local Control
