Implementation of a large scale water quality data management system

This paper looks at the application of the Generalized Planning System (GPLAN) to a large scale water pollution problem. A discussion of the GPLAN system is presented along with a discussion of its application to the Federal Water Pollution Control Act Amendments of 1972. A discussion is then presented describing what extensions were required to make the GPLAN system more adaptable to the planning process. This included extending the network query language so that it would be “relatively complete”.
