Karst zoning and channel aquifers in the karst basin at Sendang Biru Beach, Tambak Rejo Village have been investigated. Sendang Biru Beach has a cave appearance as a karst morphological feature and is composed of limestone. Seasonal karst water sources come from springs, surface runoff, underground rivers, channels in valleys, basins, and slopes that often experience drought. The purpose of this study is to identify the presence of karst aquifers and karstification zones that are prone to damage or disasters in the karst environment. The method used is a geophysical combination of Electrical Resistivity Tomography (ERT), Induced Polarization (IP), and Self Potential (SP). The results showed that the eastern part's karstification zone was characterized by moderate to high resistivity and a chargeability zone with a moderate to high range. In addition, the existence of karst aquifer channels in the anomalous zone of low resistivity, high chargeability, and negative natural potential. This zone is located in the Qas Formation, with the water flowing from west to east and from west to south. The inundated karst aquifer that spreads in a circular pattern with different depths interspersed by limestone cracks causes a heterogeneous karstification process.

“…Therefore, an alternative is the 2D/3D ERT method (another name: pseudo-3D ERT) (Kidanu et al 2020, Singh & Sharma 2022; in which the measurements are performed in the grid of parallel and/or orthogonal profiles. This method enables a flexible design of surveys, an easy selection of measurement systems, and the ease of adjusting data acquisition to 3D inversion (Torrese 2020, Okafor et al 2021.…”

A characteristic features of the geological structure of the Krakow area are tectonic horsts and grabens. The Zakrzówek Horst is one of the seven horst structures within the Krakow area, located in the south-western part of the area. It is built of Upper Jurassic limestones, where numerous karst caves have been developed. The caves of the Zakrzówek Horst probably form a system of interconnected caves. This hypothesis has been tested in the western region of the Zakrzówek Horst using the electrical resistivity tomography (ERT) method. The investigations were conducted in the parallel profile configuration as well as with the data processing procedure based on the 2D and 3D inversion. The results of these studies are an attempt to locate additional voids as well as fractured zones in the carbonate rock mass. The studies confirmed the hypothesis that the Jasna Cave is probably only a fragment of a vast cave system developed within the Zakrzówek Horst. As a result of the research carried out with the ERT method, the most prospective directions for future speleological research have been determined.

“…Based on the geophysical characteristics, various geophysical surveys have been performed such as ERT (Hong et al, 2015;Ungureanu et al, 2017), GPR (Giorgi and , seismic refraction (Giorgi and Cardenas-Soto et al, 2020), multi-channel analysis of surface waves (MASW) (Kidanu et al, 2020), gravity (Cardenas-Soto et al, 2020), frequency-domain electro-magnetic and self-potential survey (Prudhomme et al, 2019). In the urban environment, GPR survey is performed mostly due to di culty of survey due to surrounding conditions such as asphalt roads.…”

“…ERT has widely used in general also has di culties due to surrounding environment in case of urban region, however provides subsurface electrical images for a deeper depth. ERT had applied at various studies to interpret fractured rock and cavity locations (e.g., Fountain et al, 1975;Smith, 1986;Cardarelli et al, 2006;Kim et al, 2007;Ungureanu et al, 2017;Kidanu et al, 2020).

“…In order to interpret resistivity data in the urban area occurring subsidence, considering the characteristics of exploration site is signi cant in interpreting resistivity data. When analyzing the distribution of cavities and loosened weakness zone from the resistivity data, anomalies by cavities appear low resistivity in saturated condition or with high water content (Galvan et al, 2011;Hong et al, 2015;Kidanu et al, 2020), and high resistivity in unsaturated (Ungureanu et al, 2017). In addition, in case of conducting resistivity survey near the excavation region, current ow rapidly changes near the excavation region, which affects resistivity data a lot (Kim et al, 2022).…”

Ground subsidence in urban environment due to excessive development and deteriorated underground urban facilities is serious social problem. Geophysical surveys were applied to estimate distribution and scale of cavities and subsidence. In this study, electrical resistivity tomography (ERT) was performed near the subsidence occurred on road in urban area. The subsidence arose due to leak of groundwater and soil into neighboring excavation region. The survey line was located between the major subsidence area and excavation region. Since ERT data are affected by rapid topographic change or surrounding structure, influences of the excavation to data were analyzed through field-scale numerical modeling. The effect of excavation should be considered to interpret ERT data, as it can be estimated wrong anomaly. In 2D interpretation, a method of performing inversion after correcting the resistivity data including the effect of excavation was proposed. This method was proved first using the field-scale numerical model including excavation region and subsurface anomaly assuming loosened zone and then applied to field data. In addition, the ERT data were interpreted by using existing a 3D in-house algorithm, which can deal with excavation region. Both of inversion results demonstrated that conductive anomalies of loosen zone appeared stronger in more specific area compared to before considering the excavation effect.
