Résumé:
|
In the present work object-oriented analysis and design have been applied for the quality management of river systems. The physical entities of the river system, as well as the conceptual entities for the flow and water quality analysis, the simulation and the pollution control strategies, have been represented through objects. By distributing appropriate responsibilities to these objects, daily low flows of the river gauge stations can be estimated for a duration of seven and thirty days and a recurrence interval of twenty years. Based on these flows optimum windows for the whole system and minimum daily flows of the river gauge stations can be also estimated. The minimum daily flows of each point of the river system can be provided. These are the design river flows for the management study. A simple statistical analysis of water quality in the river and the effluent of the plants can be also performed and the background concentrations of major constituents can be estimated. The simulation of water quality in the system can be also performed based on the design conditions of the study. Control strategies for the improvement of water quality can be finally applied and an optimized discharge scheme can be suggested. (Abstract shortened by UMI.) |
