| The irrigation system designer normally specifies flow rates onto the bays. Changing the flow rate specifications can result in less uniform water distribution over the bays, and either - increasing deep seepage and waterlogging (with lower flow rates and longer irrigation times), or - stressed pasture (with higher flow rates and shorter irrigation times). The DPI Agnote “Border-check Irrigation Design” provides guidelines for the determination of optimum flow rates. Automation of the irrigation process minimises labour requirements. Financial assistance is available to install automatic irrigation on border-check irrigation systems in the SIR. For more information, contact your local DPI office. Spinner-cut drains are sometimes used to help get water onto the bay, or to facilitate drainage off the bay. They can be used where the supply head in the channel is limited, or where relatively flat bays do not drain well. |
