“…Many researchers have contributed toward the prediction of the occurrence of natural sinkholes via the use of diverse technologies, such as the trenching method along with ground penetration radar (GPR), electrical resistivity tomography (ERT), high-precision leveling [97], Brillouin optical fiber sensor [98], high-precision differential leveling [99], laser imaging detection and ranging (LIDAR), and interferometric synthetic aperture radar (InSAR) [100]. The combined use of the geographic information system (GIS) and analytical hierarchical process (AHP) has previously been proposed to identify hazard zones in Kuala Lumpur and Am pang Jaya of Malaysia that are susceptible to the occurrence of natural sinkholes on the basis of five criteria-lithology, groundwater level decline, soil types, land use, and proximity to groundwater wells [4].…”

Major metropolitan cities worldwide have extensively invested to secure utilities and build state-of-the-art infrastructure related to underground fluid transportation. Sewer and water pipelines make our lives extremely convenient when they function appropriately. However, leakages in underground pipe mains causes sinkholes and drinking-water scarcity. Sinkholes are the complex problems stemming from the interaction of leaked water and ground. The aim of this work is to review the existing methods for monitoring leakage in underground pipelines, the sinkholes caused by these leakages, and the viability of wireless sensor networking (WSN) for monitoring leakages and sinkholes. Herein, the authors have discussed the methods based on different objectives and their applicability via various approaches—(1) patent analysis; (2) web-of-science analysis; (3) WSN-based pipeline leakage and sinkhole monitoring. The study shows that the research on sinkholes due to leakages in sewer and water pipelines by using WSN is still in a premature stage and needs extensive investigation and research contributions. Additionally, the authors have suggested prospects for future research by comparing, analyzing, and classifying the reviewed methods. This study advocates collocating WSN, Internet of things, and artificial intelligence with pipeline monitoring methods to resolve the issues of the sinkhole occurrence.

“…This indicates that the ground has not subsided yet. This also suggests that the interpretation of radargrams should be always done in relation to the consecutive profiles, but mainly to the surface topography or with trenching [41]. It is only the physical-based proof (here the exposure of soil pipes to the surface as PCs) that may confirm the interpretation of radargrams.…”

Soil piping leads to land degradation in almost all morphoclimatic regions. However, the detection of soil pipes is still a methodological challenge. Therefore, this study aims at testing ground penetrating radar (GPR) to identify soil pipes and to present the complexity of soil pipe networks. The GPR surveys were conducted at three sites in the Bieszczady Mountains (SE Poland), where pipes develop in Cambisols. In total, 36 GPR profiles longitudinal and transverse to piping systems were made and used to provide spatial visualization of pipe networks. Soil pipes were identified as reflection hyperbolas on radargrams, which were verified with the surface indicators of piping, i.e., sagging of the ground and the occurrence of pipe roof collapses. Antennas of 500 MHz and 800 MHz were tested, which made possible the penetration of the subsurface up to 3.2 m and 2 m, respectively. Concerning ground properties, antenna frequencies and processing techniques, there was a potential possibility to detect pipes with a minimum diameter of 3.5 cm (using the antenna of lower frequency), and 2.2 cm (with the antenna of higher frequency). The results have proved that soil pipes meander horizontally and vertically and their networks become more complicated and extensive down the slope. GPR is a useful method to detect soil pipes, although it requires field verification and the proper selection of antenna frequency.

Kras kot kompleksen in heterogen sistem predstavlja za georadar velik izziv. Kljub vsemu pa lahko z dobro načrtovanimi georadarskimi raziskavami pridobimo dodatne informacije o plitvem podpovršju, kjer se odvija večina kraških procesov. Zaradi specifičnosti kraškega površja so v uvodnem delu predstavljene nekatere ovire in prilagoditveni pristopi pri raziskavah na krasu. Analiza pregleda objavljene literature je pokazala, da se georadar v kraških okoljih najpogosteje uporablja za zaznavanje jam in območij pogrezanj ter pri preprečevanju nenadnih porušitev tako v urbanih območjih kot tudi pri gradbenih posegih v prostor. Georadar se uporablja tudi pri raziskavah kraških vodonosnikov, epikrasa in raziskavah v kamnolomih. Poleg uveljavljenih aplikacij so predstavljene nekatere še neuveljavljene aplikacije, kot je uporaba georadarja pri raziskavah brezstropih jam in jamskih sedimentov. Glavni namen članka je prikazati in ovrednotiti možnosti uporabe georadarja v različnih kraških okoljih in spodbuditi njegovo uporabo za nekatere nove aplikacije in opozoriti na nujnost interdisciplinarnega pristopa v takšnih študijah.
