Water information networks: Infrastructure for efficient management of water

In collaboration with many stakeholders, NICTA, Australia’s national information and communications research centre, conducts research in the area of Water Information Networks (WIN). In this project NICTA develops information infrastructure solutions in support of efficient water (distribution) management. Researchers in WIN, in collaboration with Rubicon Systems Australia Pty Ltd (Rubicon) developed the idea of Total Channel ControlTM (TCCTM) which is patented and commercialized through Rubicon. TCCTM automates the water distribution management of large scale open canal irrigation networks with the express purpose of achieving greater efficiency. It realizes near ondemand response of gravity fed water distribution networks. As testified by a recent audit of a commercial implementation of TCCTM in the Coleambally irrigation district in New South Wales, Australia, a water distribution efficiency of 90% can be realized. Moreover gains in onfarm efficiency are simultaneously achieved due to the near “on-demand” delivery of water which allows irrigators to significantly modify their irrigation schedules, so as to better suit their local requirements. At present, WIN researchers in collaboration with the Melbourne based UniWater research centre are considering the joint automation of on-farm irrigation and distribution canals. The goal is to realize that for every drop of water “requested” by the plants in the field, a drop of water is delivered through the distribution network from “reservoir-to-the-plant”. The information infrastructure required for such a scheme is discussed. 1 Professor, WIN Project Leader, National ICT Australia, Victoria Research Laboratory and Department of Electrical and Electronic Engineering, The University of Melbourne, Vic 3010, Australia; i.mareels@unimelb.edu.au 2 corresponding author 3 WIN Research Fellow, National ICT Australia, Victoria Research Laboratory, Vic 3010, Australia; skooi@ee.unimelb.edu.au 4 WIN Project Manager, National ICT Australia, Victoria Research Laboratory, Vic 3010, Australia; gavin.thoms@nicta.com.au 5 Sensor Networks Project Leader, National ICT Australia, Victoria Research Laboratory, Vic 3010, Australia; stan.skafidas@nicta.com.au 6 Director, Rubicon Systems Australia, Pty Ltd., 1 Cato Street, Hawthorn East, Vic 3123, Australia; tony.oakes@rubicon.com.au 7 Professor and Director of UniWater, The University of Melbourne, jlai@umimelb.edu.au USCID Fourth International Conference 826
