Physical characteristics of pipes as indicators of structural state for decision-making considerations in sewer asset management
Sewer deterioration is a problem that affects many cities of the world. This affects the structural state of the sewer systems, as well as its hydraulic capacity and the service level. As a consequence, the sewer system stakeholders are working on the development of a proactive sewer management to m...
