DOI: 10.1016/j.jher.2017.08.002
Abstract: Blockages in piping systems are formed from potentially complex combinations of bio-film build up, corrosion by-products, and sediment deposition. Transient-based methods seek to detect blockages by analyzing the evolution of small amplitude pressure waves. In… read more here.

DOI: 10.1061/(asce)hy.1943-7900.0001602
Abstract: AbstractSeveral pipeline blockage detection methods assume blockages have a regular geometric shape; that is, the blocked section is a pipe of smaller diameter than the original. These methods requ... read more here.
