“…Furthermore, Cnudde and Boone [20] proved that image analysis is a reliable technique for rock pore space direct imaging and direct investigation of liquid migration. Therefore, a number of researchers [7], [14]- [17], and [21]- [23] have carried out image analysis techniques for liquid migration experiment. As mentioned by Maas and Hampel [24], image analysis technique in civil engineering field was regularly used to study the object flow absorption and liquid migration of small properties specific to structure crack extension.…”

“…Bagherieh et al [13], conducted one-dimensional drying and consolidation experiments on laboratory-prepared double-porosity kaolin soil sample. Recently, (Sa'ari et al [7]; Loke et al [11]; Alazaiza et al [14]; Ngien et al [15]; Sitthiphat and Siam [16]; and Peng et al [17]) have conducted physical experiments on double-porosity soil media. The previous listed research has contributed to the knowledge of soil characteristics in doubleporosity soil, but the studies were limited to intact doubleporosity and the reaction such as vibration effect on the double-porosity soil was never applied.…”

AbstractThe issue of leakage from underground storage tank and spillage of contaminate liquids can contribute to the aqueous and non-aqueous phase liquids contamination into the groundwater, resulting in groundwater pollution and rendering the quality of groundwater unsafe for consumption. Ensuring availability and sustainable management of water and sanitation for all was the goal and target in the 2030 agenda for sustainable development, consisting of a plan of action for people, planet and prosperity of the United Nations. This paper is intended to investigate the aqueous and non-aqueous phase liquid migrations in the fractured double-porosity soil, which become important for sustainability of groundwater utilisation and a comprehensive understanding of the pattern and behaviour of liquid migration into the groundwater. For this aim, an experiment model was conducted to study the pattern and behaviour of aqueous and non-aqueous phase liquid migration in fractured double-porosity soil using digital image processing technique. Outcome of the experiments show that the fractured double-porosity soil has faster liquid migration at the cracked soil surface condition compared to intact soil surface. It can concluded that the factors that significantly influence the aqueous and non-aqueous phase liquids migration was the soil sample structure, soil sample fractured pattern, physical interaction bonding between the liquid and soil, and the fluid capillary pressure. This study demonstrates that the hue saturation intensity contour plot of liquids migration behaviour can provide detailed information to facilitate researchers and engineers to better understand and simulate the pattern of liquids migration characteristics that influence the groundwater resources.

“…Double-porosity media have been studied in the past few decades by a number of researchers. For example, (ALAZAIZA et al, 2017;NGIEN et al, 2016;SA'ARI et al, 2015;TRANNGOC et al, 2014;RYZHIK, 2007;PAO & LEWIS, 2002) used numerical methods and experimental methods on doubleporosity soil media and have thereby contributed to an understanding of the soil characteristics. However, the studies were limited to intact double-porosity soils without applying any vibration effect on these soils.…”

Natural disasters such as earthquakes, El-Nino, tsunamis and water pollution have a negative impact on human health and living environment. Some of these may give rise to subsurface vibrations that can potentially increase groundwater pollution risks in double-porosity systems. The more complicated situation was where underground storage tanks and petroleum pipeline damage have caused the leakage of non-aqueous phase liquids (NAPLs) which migrated into the groundwater resources. These problems need to be addressed by both professionals and researchers worldwide to ensure the sustainability of groundwater utilization. This paper aims to investigate and understand NAPL migration in vibrated double-porosity soils. To do so it was necessary to study the phenomena and characteristic of soil structure and the pattern of NAPL migration to identify cost-effective remediation schemes. A laboratory experiment was conducted to study the phenomena and characteristics of vibration response and NAPL migration in double-porosity soil deformation under vibration effect using a digital image processing technique (DIPT). The outcomes of the experiment show that the gradual increase of vibration table excitation frequency yielded different vibration responses from the respective soils. This indicated that soil surface acceleration depended significantly on the soil conditions, soil water content, soil structure and the pattern of soil fracturing. NAPL migration was faster in sample 2 with 150ml toluene than sample 1 with 70ml toluene and this could be because the greater amount of toluene in sample 2 exerted an extra entry force on top of the soil sample that had yet to migrate through the sample surface. Finally, it was concluded that the DIPT may provide detailed information, and can be used to understand and identify the remediation method as well as to ensure the sustainable consumption of groundwater.

“…Maas and Hampel [15] reported that, image analysis technique in the field of civil engineering has been applied to the study of flow movement in boundary layers and liquid migration of small properties, which specific to the propagation of structure crack extension. Digital image analysis method has been used to capture and analyse liquid migration in soil under laboratory condition by Alazaiza et al [16]. As the porosity and fractured soils are difficult to observe physically, digital image processing techniques provide an attractive for the study of liquid migration in fractured double-porosity soil.…”

Aqueous phase liquid (APLs) leakage and spillage into the subsurface system, leading to groundwater contamination is an issue that needs to be addressed. This paper aims to investigate the APLs migration characteristics in fractured non-isothermal double-porosity soil. A laboratory experiment was conducted to observe and monitor the characteristics of the soil structure and APLs migration in heated deformable double-porosity soil using digital image processing technique. The results show rapid liquid migration for the fractured soil samples. The time taken for the liquid to migrate under the application of heat is less for sample with low moisture content due to faster dry off and rapid evaporation. It can be concluded that APLs migration under vibration and non-isothermal effect is highly influenced by the soil sample structure, the soil fractured pattern, the soil water content, and the applied heat in the soil.
