Uncertainty Quantification of Contamination Source Identification
Publication: World Environmental and Water Resources Congress 2008: Ahupua'A
Abstract
The problem of contamination source identification is to disclose the characteristics of contamination source intrusions (i.e., injection location, starting time, mass rate, and duration). Several models and approaches were suggested to solve this problem. All previous studies assumed that the hydraulics of the system is known (e.g., pressures, flows, consumptions, tank water levels, etc.) where in reality only partial data is available. Uncertainty thus exists in revealing the characteristics of contamination source intrusions. The objective of this study is to suggest a method for quantifying this uncertainty. The methodology is comprised of two stages: at the first stage the inverse system's hydraulics problem is solved using the available measured and water distribution system's data, for identifying possible network flow patterns; at the second stage, using the outcome of stage one, possible contamination source characteristics are found. The uncertainty of the contamination source characteristics are quantified using the results of stage two.
