Resumo

The transient condition can rupture a pipe directly through excessive pressure or they can exploit an existing weakness, like corrosion, earth pressures, construction faults, to damage the pipe indirectly. Additionally, the effects and relevance of hydraulic transients in pipeline physical degradation and the effects in inducing water quality degradation have been extensively reviewed. As water utilities are under increasing pressure to improve the quality of service (less bursts and discolouration events) while reducing leakage, it is becoming critical to better understand and control the main factors affecting failures. In addition, it is worth mentioning that monitoring and investigation of transients in operational systems is only occasionally done to investigate perceived problematic areas over a short period of time, and generally with physical focus. In this scenario, an indicator that correlates physical quantities with water quality has great relevance for the definition of projects and understanding of real hydraulic transient phenomena.
