Optimal Scheduling of Irrigation Machines. I: Model Development
(American Society of Civil Engineers, 1989)An irrigation scheduling model for a center‐pivot irrigation machine was developed to maximize returns in humid areas. A corn growth‐ and yieldsimulation model was incorporated to predict the end‐of‐season yield. The ... -
Center‐Pivot End Gun Irrigation Cost Analysis
(American Society of Civil Engineers, 1989)The analysis quantified the energy required to deliver pressure head for the area irrigated by an end gun. The energy actually used to apply water to the corner while the end gun was on and the extra energy used while the ... -
Irrigated Agriculture and Water Quality in East
(American Society of Civil Engineers, 1989)The northeastern and Appalachian states have a diverse array of geology, soils, and climate. Irrigation is concentrated in a few states, with the largest irrigation area in the Coastal Plain soils. Most of these soils are ... -
Irrigated Agriculture and Water Quality in South
(American Society of Civil Engineers, 1989)Irrigated agriculture in the humid region has resulted in more intensive management including crop production and the associated increase in fertilizer and pesticide use. Multiple cropping in most of the southeast (Alabama, ... -
Effects of Irrigated Agriculture on Groundwater Quality in Corn Belt and Lake States
(American Society of Civil Engineers, 1989)The impact of irrigation on groundwater quality is influenced by climate, topography, geology, soils, geohydrology, crops, and agricultural practices. Since the early 1950s, the irrigated crop acreage in the Corn Belt and ... -
Optimal Scheduling of Irrigation Machines. II: Applications and Results
(American Society of Civil Engineers, 1989)Application and results of a short‐range irrigation‐scheduling model for center‐pivot machines are described. The irrigation‐decision model sequentially optimizes the irrigation schedule to maximize net return from a ... -
Irrigation Impact on Groundwater: Model Study in Humid Region
(American Society of Civil Engineers, 1989)The Groundwater Loading Effects of Agricultural Management Systems (GLEAMS) model was applied to estimate the effects of: (1) Soil; (2) planting date; (3) irrigation level; and (4) pesticide characteristic on pesticide ... -
GOES Satellite Data in Rainfall Estimation
(American Society of Civil Engineers, 1989)Geostationary Operational Environmental Satellite (GOES) visible and thermal infrared data, in conjunction with the Griffith‐Woodley method, are used to estimate the rainfall in Florida. Both the life history techniques ... -
