Abstract
As has happened throughout the world. environmental and water quality problems related
to developing urban and industrial areas and associated accumulation of waste in built-up
areas were the main factors in contributing to sanitary awareness in South Africa. The
dwindling water resources and persistent deterioration of water quality, more severely in
urban areas, necessitates the review the current practice of storm water management in
South Africa. Reliable stormwater drainage models evaluating both the water quantity and
quality could be essential in confronting the prevailing pollution problems. The objective
of this project was conceived to be the development of a system for the simulation of
water quality in urban watercourses,
A personal computer compatible model for joint transportation of hydrograph and
pollutographs in open channels was developed. The model comprises an operational data
handling facility, a user friendly and interactive interface.
The study revealed that:
Urban and Industrial development results in complication of the urban water
system.
• Single objectivity approaches in management of urban watercourses are outdated .
.. The proposed model is capable of simultaneously routing flood and pollutant
condiment waves in open channels.
Understanding of aspects of the water quality in urban watercourse can be greatly
enhanced by the proposed model.
The following recommendations were henceforth made:
• Detailed study of the nature. quantity and sources of pollutants in the urban water
system.
.. 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,
