Irrigation Insights 2 - Subsurface Drainage Design and Management Practices in Irrigated Areas of Australia

It is widely understood that irrigation development results in deep percolation past the rootzone, which recharges the groundwater. With flood irrigation, watertables often rise at around 0.5 m a year until a new equilibrium is established where the watertable fluctuates from the soil surface to around 3 m deep. A significant part of all irrigation areas in Australia are currently in this condition or approaching such equilibrium. Irrigation areas in southeastern Australia, particularly in (more)...

Improving water use efficiency by reducing groundwater recharge under irrigated pastures

final report

Approximately 65% of water extracted for irrigation in Northern Victoria and over 30% in the NSW Murray Valley is applied to pastures. In 1996, Murray Irrigation Limited (MIL) introduced a Total Farm Water Balance Policy which aimed to limit farm water use to sustainable levels and hence to reduce groundwater recharge to the district watertable. The dairy industry had some concerns with the original limit of 4 Ml per hectare and initiated (more)...

Benchmarking the distribution efficiency of an irrigation supply system

Project No.GMW3 - Final Report

Project objectives To benchmark the distribution efficiency (DE) of the various components of a small, open channel gravity irrigation system and irrigation return flows from farms to the surface drainage system. To develop strategies to overcome water losses in the distribution system, including the implementation of smart systems for improved channel operations, system planning and services to improve the integration of distribution systems (more)...

Polyacrylamides in Irrigated Agriculture

Polyacrylamide (PAM) has been sold in the United States since 1995 for reducing irrigation-induced erosion and enhancing infiltration. PAM’s soil stabilizing and flocculating properties have also substantially improved runoff water quality by reducing sediments, N, ortho and total P, COD, pesticides, weed seeds, and microorganisms in runoff. The first series of practical field tests of (more)...

Irrigation Insights 1 - Information Package on Soil Water Monitoring

This Irrigation Insights information package brings together information on current equipment and techniques for measuring and monitoring soil water status, extending to their use as controllers in automatic irrigation systems. We have limited the equipment described here to those products with agents and backup within Australia. The hub of the publication is a collection of tables summarising the main product features. This enables you to compare product features. As well as technical data, (more)...
