LOCALIZATION OF THE POLLUTION SOURCE IN THE RIVER SYSTEM BASED ON POLLUTION DISPERSION
Abstract
Majority of existing simulation models is composed for simulate the pollution spreading (concentration) only downstream from the pollutant source. Consequence of this is that these models strictly require all the initial and boundary conditions (discharges, location and concentration of the pollutant). However, opposite problems may occur in practice: pollution concentration time courses in specific cross-section profile along a watercourse are known (e.g. based on the on-line monitoring), but pollution source location, as well as the pollution amount, are unknown. Such task is called ?inverse? task. The objective of this task is to determine the location of pollution source as well as the total pollution amount and time course of pollution efflux. A unique pollution source identification in river systems is very unlikely because of the river system tree structure and its branching but result of inverse task can be a selection of regions with high probability of source location. Paper presents a modelling study, focused on localisation of the pollution source of the rivers. The study is based on a real field experiment, however on a single river section without branching.
