This research is about hydraulic transients and its influence in the structure behaviour. Different numerical methods were used, being compared with the experimental tests taken in a laboratory network. The range of results from the test study of hydraulic transients presented in this research highlights the importance of accurate prediction of the pressure variations in order to ensure that a pipeline’s integrity is not compromised. To model water-hammer phenomena two different one-dimensional models were used as well as a 3D-model based on CFD (Computational Fluid Dynamics). Also, the use of FEM (Finite Element Method) to study the structural characteristics involved in the analysis of under pressure hydraulic structures pipe system.
