This work proposes an approach to detect single and multiple leaks. The task is carry out by identifying the parameters of ¯nite models associated with the leak events. The identification problem is attacked by using the Prediction Error Method (PEM). In addition, a frequency evaluation is realized to check the conditions for implementing the PEM or any other method which require an excitation condition.
