Advective water quality model for urban watercourses.

[摘要] As has happened throughout the world. environmental and water quality problems relatedto developing urban and industrial areas and associated accumulation of waste in built-upareas were the main factors in contributing to sanitary awareness in South Africa. Thedwindling water resources and persistent deterioration of water quality, more severely inurban areas, necessitates the review the current practice of storm water management inSouth Africa. Reliable stormwater drainage models evaluating both the water quantity andquality could be essential in confronting the prevailing pollution problems. The objectiveof this project was conceived to be the development of a system for the simulation ofwater quality in urban watercourses,A personal computer compatible model for joint transportation of hydrograph andpollutographs in open channels was developed. The model comprises an operational datahandling facility, a user friendly and interactive interface.The study revealed that:Urban and Industrial development results in complication of the urban watersystem.• Single objectivity approaches in management of urban watercourses are outdated ... The proposed model is capable of simultaneously routing flood and pollutantcondiment waves in open channels. Understanding of aspects of the water quality in urban watercourse can be greatlyenhanced by the proposed model.The following recommendations were henceforth made:• Detailed study of the nature. quantity and sources of pollutants in the urban watersystem... Sophisticated (dynamic wave. supercritical flow, complicated .....................hydrodynamic model snould be considered,• Biological and, chemical process in the urban watercourse be incorporated.• Linking of the water quality model to the storm water drainage model,
