This paper discusses the design of AGUAS , an agricultural water quality system, for the United States Department of Agriculture (USDA). The top level function of AGUAS is to ameliorate the impact of agriculture on water quality in a designated region of the USA. In the requirements development phase the problem of the design of AGUAS was stated in terms of I/O, technology, performance, cost, tradeoff and system test requirements. USDA policy restricts AGUAS from employing coercive technologies to carry out its top level function. Therefore, the system design requirements characterize AGUAS as an information system that outputs activities to collect data about water quality in the designated region and responses to inputted demands for information from users to persuade them to adopt less polluting farm management systems. In the concept development phase, a system design concept was chosen. Subsequently, gaps in the technology required for the implementation of AGUAS have been identified through the processes of system functional analysis and physical synthesis. Currently, the project is in a research and development phase.
