Abstract: The significance and impact of leaks in a pipeline system creates new opportunities of leak detection. In essence, the concept is to use the pressure response from a transient event to locate and size a leak. Previously, Brunone (1999) determined both the location and size of a leak on the basis of the pressure trace during a transient event at a measurement section on the basis of the well-known properties of pressure waves. More recently, formal inverse transient algorithms have been developed. The goal in this study is to see if the genetic inverse transient procedure can correctly locate and size a leak in “blind tests” of a simple and a more complicated system. More specifically, the pressure signal at the downstream end of the system as well as the basic pipe properties will be fed to the inverse procedure to see if the predicted existence, location and magnitude of the leak can be accurately determined. The paper reviews the results of the blind calibration procedures as well as summarizing the key background required to understand these developments. The significance of this study data to the later quality problem, and particularly to the danger of contamination of the pipe contents, is given special emphasis.
