“…Cross-plot analysis offers an alternative approach to integrating various geophysical parameters of co-located measurement. It provides a visual representation of the relationship between two or more attributes, aiding in the visual identification of anomalies (Austin et al 2018;Hayashi & Konishi 2010;Inazaki & Hayashi 2011). The resistivity and seismic refraction data were subjected to cross-plotting, dividing them into two distinct thresholds known as quadrant limits.…”

Near-surface characterization can be vulnerable to misinterpretation due to limited resolution and methodological limitations. Validation from different parameters is necessary to substantiate the results and reduce errors during interpretations. This research aims to develop an alternative integrated method of a 2-D cross-plot model to enhance subsurface interpretations based on the model's criteria, resulting in better geological interpretation. Geophysical methods such as electrical resistivity and seismic refraction are utilized in a test model and a case study area to observe the capabilities of the integrated method approach. The goal of this study was to cluster two or more different parameters into a single model for a direct presentation of the subsurface model. This includes the characterization of subsurface properties, data integration using cross-plot analysis, and the development of a 2-D cross-plot model. This method visually represents the relationship between two or more attributes, allowing for the identification of anomalies. In the test model, the lithology consists of sandy silt derived from granitic residual soil, whereas in the case study model, it was dominated by weathered granitic residual soil with the presence of saturated zones. The 2-D cross-plot model provides a comprehensive interpretation where Quadrant, Q1 shows the vulnerable zones for sliding mass bodies. The plane weakness was successfully identified based on the cross-plot model as the weathered zone, and subsurface features were determined. The estimated volume of mass movement was successfully calculated for the case study area based on the determination of the sliding plane. The integrated method of cross-plot analysis along with the development of 2-D cross-plot models proves to be an informative approach for subsurface characterization and enhances subsurface imaging.

“…One of the most used methods, in this case, is also electrical resistivity tomography (ERT), also called the resistivity imaging (RI). In most cases, the 2D ERT technique was applied [14][15][16][17][18][19][20][21][22][23]. It is worth mentioning that the aforementioned methods are the common applied techniques and most effective for studying the internal structure of levees.…”

“…It is worth mentioning that the aforementioned methods are the common applied techniques and most effective for studying the internal structure of levees. The electromagnetic profiling (EMP) method, also called the ground conductivity meter (GCM), is less popular than the previous one and It uses relatively fast recognition of the levee [15][16][17][18][19][20][21][22][23][24][25][26]. Amongst seismic methods, the refraction and multichannel analysis of surface waves (MASW) techniques are applied for this purpose [27,28].…”

Application of Complex Geophysical Methods for the Detection of Unconsolidated Zones in Flood Dikes

The flood levees in the vicinity of Krakow city (Poland) are, in some places, over 100 years old. Thereupon, in the flood dike, and its subsoil, can appear unconsolidated zones, which, during the flood stage, can be a simple way of water flow and/or even can be the place where the levee body will be destroyed. This phenomenon took place in Wawrzeńczyce village, near Krakow city, during the flood in 2010. The geophysical research was carried out, in order to develop a methodology of recognition of potential areas where the levee body can be damaged. The geophysical surveys were conducted with the use of electrical and electromagnetic methods, as well as utilizing the seismic method. The general identification of examined media was realized by the electrical resistivity tomography (ERT) method. The ERT surveys were supplemented by capacitively-coupled resistivity (CCR) measurements, in order to analyze the usefulness of the CCR method for the examination of river dikes and reduction of interpretation ambiguity. The ground penetrating radar (GPR) method detected small anomalies in the body dike, due to the very high resolution of this method, which were not detected by the ERT and CCR techniques. During GPR surveys, non-standard measurement techniques were applied. Finally, the high-resolution seismic reflection (HRSR) method provided a clear and high-resolution image of the dike structure up to the water table and assisted with the identification of the hazard non-consolidated zones.
