Outline the background to the project., My current role within the Australian Cotton CRC and CSIRO involves the, development, application and field-testing of computerised decision support tools in, the cotton industry. At present this involves the OZCOT cotton simulation model, and the Water Use Efficiency Calculator, and in the future the HydroLOGIC water, management tool. The purpose of this travel proposal is to attend the 18th, International Congress on Irrigation and Drainage (ICID), 21-28 July in Montreal,, Canada, and to visit cotton researchers and extension staff in the San Joaquin valley,, California. An important motivation for this proposal is to broaden my knowledge, of water management, which will assist the development and application of the, OZCOT and HydroLogic tools, and to remain up-to-date with current research in, the area of DSS, irrigation management and on-farm application adoption, techniques.
