“…This suggests the conductivity of peat pore water at Parit Nipah increases with depth. As mentioned by Kim et al [26], the conductivity of pore fluid affects the resistivity of soil. At the transition layer between peat and soft clay the resistivity value decreased drastically due to the presence of clay fraction.…”

The pre-construction works include the geotechnical investigation which comprises the surface and subsurface exploration. Sub-surface exploration often causes several difficulties such as high cost, time consuming, localized investigation and intrusive. Furthermore, investigation on soft soil such as peat often raises several additional problems such as high risk of sample disturbance, difficult access for heavy equipment and inconsistent data due to the heterogeneity of peat. The advancement of geophysical method such as Electrical Resistivity Tomography (ERT) allows the determination of soil profile in time-efficient manner, economic, larger volume of investigation and non-intrusive. This study focused on the determination of soil profile, particularly peat layer using ERT method with complement from peat sampler data. The study was conducted at Parit Nipah, Johor. The results revealed a high accuracy profile delineated by the ERT method with only less than 8% percentage of error as compared to peat sampler profile. The comparison between Schlumberger and Wenner array showed that; the Schlumberger showed superior depth of penetration, with almost 3 times deeper penetration relative to Wenner. The Schlumberger array is also able to delineate lateral variation within the peat layer. Finally, the resistivity value of peat obtained ranged from 100.8 to 139.5 ohm.m with both arrays having consistent results.

“…Among the sources of groundwater contamination, may be agricultural pollutants such as fertilizers and pesticides from the use in paddy field (Jeyaruba & Thushyanthy, 2009;Vandermaesen et al, 2016) Commonly, fractures in subsurface indicate the present of groundwater. The lower the resistivity values may exhibit the greater the fractures are (Kim et al, 2011). From Profile B, it can be assumed that the fractured zone is a zone area with high potential groundwater source.…”

2-D electrical resistivity has been a proper investigation survey for determination of subsurface geophysical in describing the complex features geology profile. In this study, an electrical resistivity survey was conducted at paddy cultivation area located in Melor, Kelantan, Malaysia. Since the end plot of paddy field experiences water scarcity especially during dry season, there is a need to find other alternative water source. The study was conducted on 1st and 2nd February 2020 to identify zone area of groundwater for Melor, Kelantan. Four resistivity lines using Induced Polarization (IP) and 2-D Electrical Resistivity Imaging Technique were conducted using a set of ABEM Terrameter SAS4000. Short resistivity survey was applied to gained detail of subsurface formation near the ground, while the longer resistivity survey was applied to obtain deeper subsurface delineation. Measured data obtained was analyzed using RES2DINV software and result of contrast resistivity values was used to determine the geological structures, while the chargeability values were analyzed accordingly to determine area of expected potential groundwater zone. Results from the resistivity profiles show a range values of 0 Ωm to 50,000 Ωm with total maximum acquired depth of 65.6 m below ground surface. The chargeability profiles show a range values of 0 msec to 500 msec, that shows potential of groundwater zone area lies at 0 to 4 msec. It was found that at a depth of 60 to 75 m, 30 m from center of Profile B was suitable for a production well which was expected to be a potential area for groundwater zone.

“…The frequency of the geophones should be adequate to sliding objectives. Typically, in shallow seismic investigations, particularly landslide studies, the natural frequency used is 4.5 Hz (Capizzi and Martorana, 2014;Glade et al, 2005;Havenith et al, 2002;Havenith et al, 2000;Imani, 2020;Imani and Tian, 2018;Imani et al, 2021b;Jongmans et al, 2009;Karslı et al, 2017;Kim et al, 2011;Uhlemann et al, 2016;Vanlı Senkaya et al, 2019). However, geophones with higher frequencies (10, 14, and 28 Hz) are likely applied in sliding studies (Adamczyk et al, 2013;Bekler et al, 2011;Donohue et al, 2012;Glade et al, 2005;Godio et al, 2006;Grit and Kanli, 2016;Jacob et al, 2018;Mezerreg et al, 2019;Ng et al, 2015;Travelletti et al, 2010;Wang et al, 2016;Zainal Abidin et al, 2012).…”

“…The application of near-surface geophysical techniques has extensively increased. These methods can give reliable results obtained from the slope with a non-invasive, quick, and user-friendly technology (Al-Saigh and Al-Dabbagh, 2010;Bekler et al, 2011;Bichler et al, 2004;Capizzi and Martorana, 2014;Chen et al, 2019b;Donohue et al, 2012;Ferrucci et al, 2000;Göktürkler et al, 2008;Grit and Kanli, 2016;Havenith et al, 2002;Havenith et al, 2000;Imani et al, 2021a;Imani et al, 2021b;Jacob et al, 2018;Jongmans et al, 2009;Jongmans and Garambois, 2007;Karslı et al, 2017;Kim et al, 2011;Kul Yahşi and Ersoy, 2018;Mauritsch et al, 2000;Mezerreg et al, 2019;Ng et al, 2015;Nwankwo and Ugbena, 2019;Otto and Sass, 2006;Ozcep et al, 2012;Samyn et al, 2012;Solberg et al, 2012;Tomás et al, 2018;Travelletti et al, 2010;Wang et al, 2016;Yilmaz and Kamaci, 2018).…”

Since the early 1960s, near-surface seismic refraction tomography (SRT) has been extensively used as a non-invasive and cost-effective geophysical method to characterize complex geological structures for landslide investigation. This geophysical technique is able to characterize the slope material, the sliding surface's geometry, the landslide mass movement, the physical properties of media, and the water saturation effects on the slope. Therefore, this method has become an appropriate method due to the increasing progress of novel algorithms and the improvements of field-data collection systems. In this paper, we attempt to review the essential research that investigated various types of landslides influenced by water saturation and landslide materials and identified in various areas, since the year 2000. Significant conclusions obtained by applying different survey strategies and data processing algorithms in seismic refraction surveys are widely discussed concentrating on the advantages and disadvantages of this method. The main results obtained by the few available studies applying time-lapse SRT (TLSRT) are particularly analyzed.
