Optimal Irrigation Planning for Drought Management in Lower Colorado River Basin
The Lower Colorado River Authority (LCRA) of Texas recently completed a Drought Management Plan (DMP) for the water supplies under its control. In developing that plan, the LCRA evaluated...

Integrated Management of Sugarcane Mill Wastewater for Bioenergy Production and Drip Irrigation
Based on the previous work of wastewater characterization and relevant literature review, a combined anaerobic (UASB) and aerobic (EAFB) treatment of supernatant of settled sugarcane mill...

Ground Water of the Canterbury Plains, New Zealand

Automated Lysimeter for Irrigation and Drainage Control
Knowledge of crop evapotranspiration (ETc), the combined process of evaporation and plant transpiration, is important in agriculture for scheduling...

Lysimeter Studies in Irrigated Soils of South Eastern Australia
The Riverine Plain of south eastern Australia is an extensive, predominantly clay soil area with large surface irrigation schemes. Early lysimeter installations were used to estimate evaporative...

Lysimeter-based Water Balance Study in Japan
Research on the water balance of agricultural land has been conducted using lysimeters for various objectives in Japan since the 1950s. In this paper, research for two major objectives...

Water Table Lysimeter Data Interpretation
Lysimeters were used to estimate seasonal water use of wet meadows and phreatophytes in northern Utah, southeast Idaho and southwest Wyoming (1983-1990). Twelve water table lysimeters...

Drainage Lysimeters for High Water Table Citrus Studies
Forty drainage lysimeters were installed in 1988 to conduct water quality and consumptive use studies for citrus. The lysimeters were designed to simulate the high water table conditions...

High Saline Water-Table Effect on Wheat Irrigation
Hydraulic, weighing lysimeters were used for five years to measure the effect of high, saline water tables on irrigation requirement of wheat. Each year the wheat was grown with no water...

Temporal Ion Balance Variation of an Irrigated Soil
The research was carried out in Southern Italy, from 1983 to 1988, using two gravity lysimeters irrigated with non saline water. The objective of this study was to test wether long-term...

Installation and Operation of Large Drainage Lysimeters on Grapes
Six large (3.05 m × 3.66 m × 1.83 m) drainage lysimeters were installed in 1984 in the middle of a 1.2 ha trickle irrigated experimental vineyard. Each was planted to two V. vinifera grapevines....

Relationship Between Lysimeter Area and Evapotranspiration (ET)
The lysimeter is an important instrument for measuring evapotranspiration (ET) of crops. It is widely used in the irrigation and drainage experimental stations in China. However, the areas...

Use of Lysimetric Measurements for Designing Major Irrigation Systems in the USSR
The bioclimatic method for calculation of crop water requirements has been widely used in the USSR in recent years. The author has analyzed the results of its application for designing...

Lysimetric Monitoring for Operation of Irrigation Systems in the USSR
The author suggests a new method for operational control of irrigation regimes which is based on monitoring of a number of critical parameters related to the yield potentials of crops....

Infiltration of Unconsumed Irrigation Water in Utah
The ground-water hydrology of Panguitch Valley and adjacent areas, south-central Utah, was studied during 1988-90. One objective of the study was to measure ground-water recharge from...

Water and Salt Movement Under Trickle Irrigation
Experiments have been conducted to study the effect of the drip irrigation parameters on the movement of water and salt in the trickle wetted soil volume. The study indicated that for...

Farm Irrigation Rating Index (FIRI)—A Procedure to Evaluate Both Irrigation Systems and Management
The Soil Conservation Service USDA/SCS, concentrates it's technical assistance to cooperators on improvements of on-farm irrigation systems and improvements of water management...

Operation of Irrigation System and Water Management in Low Lying Paddy Area with Creek Network
Characteristics of the operation and management of irrigation systems were analyzed in the low lying paddy area with creek networks. The irrigation system in Kubota district was chosen...

Effect of Frequency on Center Pivot Irrigation
Processes that are affected by the irrigation frequency of center pivot irrigation systems are described. High frequency irrigation will increase evaporation from crop canopies and unshaded...
