A MODEL SYSTEM FOR ADVANCED MANAGEMENT OF ACCIDENTAL TOXIC SPILL IN DRINKING WATER SOURCES: LAKE VOMB CASE STUDY
A model system for advanced management of accidental toxic spill in drinking water sources is described. The system is based on the 1-D river model RIVTOX and 3-D lake model THREETOX. The model system was applied to the Lake Vomb catchment, which is located in the south of Sweden and from which approximately 400 000 people get their drinking water. The hydrodynamics and water contamination of the system including the branch of the Björka river (from the river mouth to the bridge at 7 river km upstream) and the Lake Vomb have been simulated by the implementation of this model system. The river and lake hydrodynamics parameters were simulated in typical hydro-meteorological conditions, that were used for the simuladon of the consequences of a 1000 kg toxin release into the water near the bridge. The dispersion ofa conservadve tracer, a first order decay pollutant (phenol) and a contaminant interacting with the sediments (Sandoz kind pesticide) have been studied. “Complete abstract not presented.”
