Estimation of Standard Deviation of Potential Evapotranspiration
Publisher: American Society of Civil Engineers
Abstract: Some weather simulation procedures require mean values of potential evapotranspiration (ETP) and the standard deviations in ETP. For purposes of irrigation planning and design it may be desirable to know the probable ...
Simple Laboratory Measurement of Unsaturated Hydraulic Conductivity
Publisher: American Society of Civil Engineers
Abstract: A simple method called “upward infiltration method” is described for using common soil laboratory equipment to measure unsaturated hydraulic conductivity of soil samples in a short time. The method is based on measurement ...
Economic Considerations of Deficit Irrigation
Publisher: American Society of Civil Engineers
Abstract: The factors related to potential yields of crops are briefly described. The most important are water, fertility, and available energy as measured by the evaporative potential. Mathematical yield models are presented relating ...
Closure to “<i>Economic Consideration of Deficit Irrigation</i>” by George H. Hargreaves and Zohrab A. Samani (December, 1984)
Publisher: American Society of Civil Engineers
Simplified Irrigation Scheduling and Crop Selection for El Salvador
Publisher: American Society of Civil Engineers
Abstract: A unique condition exists for the country of El Salvador: By knowing only the elevation, the type of crop suitable for the area and the crop water requirement can be evaluated. This paper shows how elevation can be used ...
Modeling Yields from Rainfall and Supplemental Irrigation
Publisher: American Society of Civil Engineers
Abstract: Frequently, the area of good soils suitable for irrigation far exceeds that for which adequate water is available for maximum crop production. Decisions and/or policies are often required relative to how much land should ...
Remediation of Chromium‐Containing Soils by Heap Leaching: Column Study
Publisher: American Society of Civil Engineers
Abstract: Efforts are being made to devise technologies and treatment systems to remediate contaminated soil on site without generating significant wastes for off‐site disposal. Heap leaching, a technique used extensively in the ...
Modeling Capillary Rise in Clinoptilolite Zeolite and Riparian Soils to Sustain Vegetation in Water-Scarce Areas
Publisher: American Society of Civil Engineers
Abstract: Clinoptilolite zeolite (CZ) is being considered as a wicking material for revegetation of riparian regions in arid environments where depth to groundwater is less than 3 m. Simulation of water fluxes and water contents ...
Water Budget Calculator Created for Residential Urban Landscapes in Albuquerque, New Mexico
Publisher: American Society of Civil Engineers
Abstract: The current methods used to calculate urban landscape water budgets are limited because they lack site specificity. The objective of this study was to create a landscape water budget web interface based on ground-proofed ...
Correcting the Edge Effect for Sensor Spatial Response in Evapotranspiration Estimation through Remote Sensing
Publisher: ASCE
Abstract: Recent advances in remote-sensing technology using multispectral images provide a powerful tool to estimate crop-water evapotranspiration (ET) at the watershed scale with large spatial and temporal precision. However, most ...
