“…As a result, it will cause ecosystem damage and pollution contamination, especially seawater intrusion and contaminants. According to the study [23], karst areas are discontinuous due to a lack of surface water drainage due to cracked and porous rocks. That will cause the river to flow below often.…”

offers significant tourism and fisheries potential, supported by the nearby Sempu Island Nature Reserve and a Fish Auction Site (FAS). However, the coastal region is prone to karstification, which may be exacerbated by recent land use developments in the surrounding area. This study aims to analyze the rock layer structures and assess the vulnerability of karst land use to the ongoing karstification process. Electrical Resistivity Tomography (ERT) and Magnetotelluric (MT) methods were employed to investigate karst land within the study area. The findings revealed the presence of karst aquifers in Zone A, extending to a depth of 250 m, characterized by low resistivity values. In Zone B, karst limestone deformation was observed at several locations due to karstification, with moderate resistivity values detected at a depth of 300 m on the surface, indicating vulnerability to karst disasters. High resistivity values dominated areas with massive karst limestone, ranging from the surface to a depth of 400 m. Furthermore, it was found that a significant portion of karst land is utilized for settlements, plantations, and rice paddies, potentially disrupting the karst ecosystem due to household, plantation, and agricultural waste. This study highlights the importance of understanding the impact of land use on karst vulnerability and informs mitigation strategies for sustainable development in the Sendang Biru region.

“…Figure 2 (c-h) shows low resistivity, located in the western part of lines 1, 3, and 6 at a depth of 15 m to 40 m. That is interpreted as a layer of limestone saturated with water, and the clay layer is the main karst water channel (conduit) [10,40,41]. This spring is an open sinkhole located on lines 1 and 6.…”

“…At moderate resistivity with a depth of 15-40 m, some researchers have interpreted it as a layer of limestone that is saturated with water and a layer of clay in the form of a karst main water channel (conduit) [10,40,41] with springs in the form of open sinkholes. However, it is different from lines 2 and 5, which are also indicated as moderate resistivity zones.…”

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.

Geomorphological Risk and Denudational Index (Land Erodability) in Karstic Terrain of Anina Mining Area (Banat Mountains, Romania)

Anina Mining Area was defined by Vasile Sencu in 1977 as the area that is surrounding Anina town and may be exploited by mining activities. The aim of this paper is to present two parameters regarding geomorphometry in Anina Mining Area, naming here Geomorphological Risk and Denudational Index (Land Erodability Index). These two morphometric parameters are obtained using geomorphological parameters that we obtained in previous works, as slope, hypsometry, drainage density, depth drainage and morphodynamic potential. The methodology to derive Geomorphological risk and Denudational index (Land Erodability Index) is based on GIS techniques. The results we obtained point out that the study area of this paper is a region where parameters such as geomorphological risk and denudational index have small incidence. This fact is due to the large homogeneous areas from the standpoint of geology and land cover, but also as an effect of large surfaces with a planar aspect as karstic plateaus. From the analysis of these two parameters we must conclude that Anina Mining Area represents a space with small surfaces which are prone to risks associated with geomorphological process and also with small areas where denudation may have high rates due to the large areas where vegetation is present and also due to large plateaus where the primary processes are related to karstification, and these ones are very slow processes.
