Simulation model to assess pollution caused by storms
Urban development is radically affected by environmental hazards such as storms. That is why urban storm water management is important in order to ensure that factors such as the discharge of pollutants to surface waters as well as soil and ground waters can be adequately assessed. A simulation model of the polluting affects of storm water has been designed as part of the DAYWATER project. It is capable of simulating long-term continuous effects of storm water as well as the impact of a single event. It can examine storm water treatment and calculate for large catchments. It can be suitably applied to dimensioning facilities for the treatment of combined sewage. As part of the planning feature which is incorporated, the model can plan single measures to entire drainage systems with on site and central elements. It can account for rainwater retention tanks, central infiltration facilities and rainwater sedimentation tanks. The model can be used for studies, to test concepts and by architects and engineers for their planning phases. It is suitable for dimensioning by means of long-term simulation and has great flexibility because of its object-orientated programming. Variable customisation of the system behaviour is also possible. Other characteristics of the software include an intuitive graphical user interface and CAD graphics in dwg (drawing) and dxf (drawing exchange) formats, GIS systems and aerial photos.
