Application of dedicated monitoring: network design for unknown pollutant-source identification based on dynamic time warping

AbstractImplementation of monitoring strategy for increasing the efficiency of groundwater pollutant source characterization is often necessary, especially when inadequate and arbitrary concentration measurement data are initially available. The research reported in this paper focuses on estimating three main parameters that are essential for efficient and accurate characterization of groundwater pollution sources, as follows: (1) location of source, (2) its starting time of release, and (3) duration of its activity. Most of the methodologies developed so far for unknown pollutant source identification have not adequately addressed the complexities involved with estimation of starting time of release and the duration of activity. Estimation of the time gap between the first observation of contamination in the aquifer at a location and the starting time of release is important for source identification. The main complexity arises due to the fact that the spatial location and the duration of activity of a p...
