Abstract
The series of computer programs known as QUAL-II has a long history in systems analysis in water quality management. The continuing cycle of testing and refinement of the computer program accounts for its many strengths as most of the weaknesses have been uncovered in this process. In its current release, called QUAL2E, the computer program represents the state-of-the-art in a general purpose, steady-state water quality simulation model. EPA is using the program as a vehicle for demonstrating systems analysis techniques, including uncertainty analysis methodologies to aid model calibration and gain insights into predictive ability and expert systems technology to develop an intelligent user interface.
