Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...

Stochastic Simulation and Optimization of Irrigation Canal Network Flows
This paper investigates the effects of parametric and objective uncertainty on simulation and optimal hydraulic design of irrigation canal networks. A model of spatially-varied flow in...

Introduction to Remote Sensing for Irrigation and Drainage
Remote sensing is a rapidly emerging technology that has many potential applications to irrigation, drainage and hydrologic engineering. This paper, the first of four, introduces the reader...

Applications of Remote Sensing to Irrigated Agriculture
Several uses for satellite digital imagery and data from portable field radiometers have been developed for the monitoring of agricultural crops, their yields, insect and disease attacks,...

An Interagency Program to Improve Irrigated Agriculture
An interagency Management Improvement Program (MIP) has been initiated to develop, apply, and evaluate the MIP methodology as a way to improve resource management and organizational effectiveness...

Agricultural Option Contracts
A plan for developing and implementing option contracts on agricultural water supplies by municipalities in Northern Colorado is presented. Two water supply projects - the Colorado-Big...

Reclaimed Water, Irrigation, and Conservation Pricing
The Irvine Ranch Water District (IRWD) is located in the south-central portion of Orange County consisting of approximately 76,000 acres. The most extensive reclaimed water project in...

Reuse Rules
Cities that discharge sewage effluent to surface water are under increasing pressure to reduce concentrations of heavy metals, ammonium and nitrate, and substances such as toxic organic...

Research Study of Highway Snowdrifting in Canada
Millions of dollars are spent annually to maintain Canadian highways in order to make them safe for motorists during the winter. In Ontario, it is estimated that on average $3,000/km of...

Wastewater Reclamation and Reuse for Malibu, California
Engineering-Science is providing consulting engineering services for the design of a sewer system and wastewater reclamation plant for the urban portion of Malibu, California. This project...

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...

Effects of Sea Level Rise on the Mississippi River Delta Plain
Geologic studies of the Mississippi River delta plain and continental shelf reveal the occurrence of several relative sea level stillstands during the last stages of the Holocene transgression....

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...

Salinity Problems Associated with Reuse Water Irrigation on Southwestern Golf Courses
One of the most severe of the potential reuse water quality problems is salinity. While many water supplies in the southwest have relatively high total dissolved solids (TDS) concentrations,...

Automated Lysimeter for Irrigation and Drainage Control
Knowledge of crop evapotranspiration (ET_c), 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...

Percolation Lysimeters for Water Quality Sampling
A field method to measure, year-around, the quantity and quality of leachate under irrigated crops has been developed. A specific objective was to evaluate percolation lysimeters as tools...

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...
