Buried pipelines are an essential component of the urban infrastructure of modern cities.
Traditional buried pipes are mainly made of metal materials. With the development of …

This paper is concerned with time delay estimation for the detection of leaks in buried plastic
water pipes using the cross-correlation of leak noise signals. In some circumstances the …

Acoustic techniques have been used for many years to find and locate leaks in buried water
distribution systems. Hydrophones and accelerometers are typically used as sensors …

Leakages in water distribution networks are a common issue encountered in the water
industry. The acoustic cross-correlation method is generally employed for detecting and …

Water companies are under constant pressure to ensure that water leakage is kept to a
minimum. Leak noise correlators are often used to help find and locate leaks. These devices …

The detection and location of pipeline leakage can be deduced from the time arrival leak
signals measured by acoustic sensors placed at the pipe. Ongoing research in this field is …

Acoustic correlators have been used for many years to locate and detect leaks in buried
water distribution pipes. Currently, the only way to compare different correlators directly is in …

The problem considered in this paper is assessing the quality of the time delay estimate
between leak signals measured on water pipes. This is practically important, as a …

This paper proposes a method for estimating wave speed and locating leaks in water pipes
using multipath identification techniques. The wave speed and leak location are determined …

Leaks in pipes are a common issue encountered in the water industry. Acoustic methods are
generally successful in finding and locating leaks in metallic pipes, however, they are less …
