The accidental water pollution arises from inflow of chemically-polluted water by a fire disaster, a traffic accident, a breakdown of sewage treatment plant, and so on. In Paldang reservoir that is a source of water supply to 23 million people, there is a storing possibility that the accidental water pollution will happen because a pollution source and a water intake facility co-exist in the same region. Thus, to protect water resources from the accidental water pollution, it is necessary to develop a early forecasting and alarm system at Paldang watershed.
In this study, historical accidents of the water pollution were reviewed, and cases of the system for forecasting and alarm from the accidental water pollution were searched to employ a proper type to Paldang watershed. Then the numerical model for forecasting water quality, RAMS(river analysis modeling system), was selected, and the behavior of pollutants was calculated based on several scenarios of the accidental water pollution by means of the numerical model. Also managemental plans for situation of the accidental water pollution happening at Paldang watershed were simulated. According to the simulating results, a plan of increase of discharge at Cheongpyeong Dam reduced the peak concentration of pollutants, whereas extended the time for stopping water intake. Another plan, drop of water elevation at Paldang Dam, decreased seriously the time for stopping water intake although there were a little effect to decrease the peak concentration. Thus it was concluded that appropriate combinations of the plans for the increase discharge and the dropping water elevation should be used to deal with the accidental water pollution.
The system for forecasting and alarm from the accidental water pollution should have two elements; The system should predict exactly the arrival time and dispersion of harmful substance in Paldang reservoir. The system should show the available results without delay. In order to satisfy these conditions, the system is based on real-time input data giving information about the accident as well as water discharge and water quality, which can be retrieved from the main warning stations via remote transmission from the gauging sites. Also the system should have a early warning module based on UMS(unified messaging system) to spread effectively the situation of the accidental water pollution among the citizens.
