Pipeline surface defects such as cracks cause major problems for asset managers, particularly when the pipe is buried under the ground. The manual inspection of surface defects in the underground pipes has a number of drawbacks, including subjectivity, varying standards, and high costs. An automatic inspection system using image processing and artificial intelligence techniques can overcome man...

The backfill quality of a pipeline has an important influence on operation. When loose is used, the may be damaged after short term In this study, numerical simulation analysis buried pipes was carried out under three conditions: around pipe, dense backfill, and controlled low strength materials (CLSM) backfill. effects narrow trench backfilling using CLSM force deformation pipelines were studi...

We propose a methodological tool for examining the layout and revealing the concealed characteristics of urbanwater supply systems (WSS). For this purpose,we use underground images obtained with ground penetrating radar (GPR) as a method that does not alter the system conditions and environmental characteristics (non-destructive methods). The study focuses on wave amplitude and uses intensive m...
