Selection of an appropriate combination of flow rate and time to cut-off is critical to the achievement of high performance furrow irrigation. For the cotton growing regions of Australia the ready availability of land and the relative scarcity of water impose a constraint not present in all surface irrigation areas. In this situation the objective is to improve water use efficiency by maximising application efficiency. In this paper, simulations employing this strategy and historical furrow irri...

Over a number of years the cotton industry (CRDC) has been supporting NCEA in the development and demonstration of a system for the ‘smart’ automation of furrow irrigation. The system currently undergoing final trials consists of three major component parts. The core component is automation hardware and software initially developed for bay irrigation and which is available commercially from Rubicon Water under its FarmConnect system. This provides: • precise, automated control of flows throughou...

Surface irrigation is the term used to describe the range of application techniques by which water is delivered to one or more points or edges of a field, and distributes over the field area under the influence of gravity. Surface irrigation is often referred to as flood irrigation, implying that the water distribution is uncontrolled, and, therefore, inherently inefficient. The term encompasses a large range of systems with varying degrees of complexity and performance. It is true that a signif...

Automated furrow irrigation systems have been successfully installed and operated on 160 ha of furrow irrigation, on three farms located across the Burdekin sugarcane growing region. The once labour intensive manual irrigation management has been transformed by allowing growers to control, schedule and monitor the behaviour of the pumps, pipeline and valves remotely from a computer, tablet or smartphone. Significant reductions of energy, water, labour and travel associated with irrigation manage...

Previous evaluations of bay (or border check) irrigation in northern Victoria have shown that higher irrigation flows offer very much improved (volumetric) application efficiencies, well above those currently achieved. However, having the correct irrigation duration (or time to cut-off) is critical in reaching those efficiencies. Automation of bay irrigation provides the needed precision in managing the shorter irrigation durations that result from the higher flows. Hence, the objective of the s...

AbstractSeepage from open channels is a major source of water loss across all irrigation districts in Australia. Pondage tests are acknowledged as the best direct method for seepage measurement, and the recorded water-level data from automated systems during periods of gate closure can be treated as pondage test data. A computer model that applies pondage test methodology to automated channel control data during periods of shut down in order to estimate seepage rates in different channel reaches...

A model is described which applies the full one-dimensional version of the Saint–Venant equations for open channel flow to simulate the process of surface irrigation. The resulting software for surface irrigation simulation, calibration and optimisation, abbreviated to SISCO, was developed for use in a standard PC environment. Unlike some other models currently in use, SISCO can accommodate temporal variations in inflow rates and spatial variability in soil infiltration, surface roughness, slope...

Surface irrigation methods are simple, mostly gravity driven and therefore have low energy requirements. However, these systems are often seen as being inefficient both in labour and water usage. As the competition for the scarce water resources and greater emphasis on environmental conservation gain ground, more focus has been directed towards surface systems. On the one hand, some irrigators have converted to pressurised systems which are seen by some to be more water efficient. This is reflec...
