“…The combination of geotectonic regime map with the geological map indicates that in this area predominate Cretaceous rocks on the surface (Figure 10), with mainly Late Cretaceous covering more than 69% of the area (Table 2). This indicates uplift and the erosion of the youngest geological formations, according to the results of other studies (Buccolini et al, 2014;Wu et al, 2014). This uprising regimen is corroborated by the presence of Holocene colluvial sediments formed by piedmont deposits covering 27% of the area, with the few alluvial deposits identified in the area revealing a sector of uprising, where erosion processes predominate compared to cumulative processes.…”

The study present the use of Geographic Information System (GIS) to assess the geotectonic regimen of the Sabinas Basin. Initially, the GIS database was designed using geological and geophysical information (total magnetic field reduced to the pole). Subsequently, 2D models of the basin were obtained along 4 profiles running on a north-south direction. The implementation of GIS enables a geological-geophysical interpretation generating various thematic maps that overlap the magnetic map during interpretation. The analysis of overlapping maps enables the identification of areas with different geotectonic regimes in the Sabinas Basin, as well as the relationship between these environments and mineralization. The qualitative and quantitative interpretation of the aeromagnetic data obtained for the total magnetic field reduced to the pole delineate uplifted basement areas as well as shallower blocks within them. This paper presents the location of both the basin´s deepest zones and its probable faults, which can be linked to the block boundaries. The faults zones and block boundaries correspond to the main mineral deposits found in the basin. Finally, the geotectonic regime of some sectors of the basin is detailed in order to reaffirm the results obtained by the interpretation of aeromagnetic data. Se presenta el uso de un Sistemas de Información Geográfica para evaluar el régimen geotectónico de la Cuenca de Sabinas. Inicialmente se llevó a cabo el diseño de la base de datos del Sistema de Información Geográfica, teniendo en cuenta las características de la información geológica y geofísica (campo magnético total reducido al polo). Posteriormente se obtienen modelos 2D de la cuenca a lo largo de 4 perfiles con direcciones norte-sur. A partir de la implementación del Sistema de Información Geográfica, se logró una interpretación geológica-geofísica, generando diversos mapas temáticos que se superpusieron al mapa magnético durante dicha interpretación. El análisis de los mapas superpuestos permitió identificar áreas con diferente régimen geotectónico dentro de la Cuenca de Sabinas, así como la relación de esas áreas con mineralizaciones. A partir de la interpretación cualitativa y cuantitativa de los datos del campo magnético total reducido al polo se delimitan áreas levantadas del basamento de la cuenca y los bloques más someros dentro de las mismas. También se localizan las zonas más profundas de la cuenca y probables fallas, que pueden estar vinculadas con los límites de los bloques. Las zonas de fallas y los límites de bloques están relacionados con los principales depósitos minerales de la cuenca. Por último, se detalla el régimen geotectónico de algunos sectores de la cuenca, para reafirmar los resultados de la interpretación de los datos aeromagnéticos. ABSTRACT RESUMEN

“…As shown in Figure , a possible short‐term evolution sequence can be proposed, in which in a first phase landslides occur in hillslopes (phase I in Figure ) displaying appropriate predisposing factors (see Vergari et al ., for a landslide susceptibility analysis of the area). This phase is exacerbated by highly erodible bedrock lithology and by Holocene and recent river entrenchment (Buccolini et al ., ). These instability events temporarily interrupt the hillslope/channel connectivity.…”

This paper explores the effectiveness of the widely‐used functional relationship between drainage area (A in m2) and slope (S in m/m) to identify local process domains and aid interpretation of process interactions in a complex badland landscape. In order to perform this investigation, a series of sub‐basins tributary to the Formone River in the Orcia catchment (central Italy) were selected as a suitable study area within which to explore our questions, given these basins' general representativeness of local terrain, the availability of a high resolution digital terrain model and previous extensive geomorphological research. Eroding basins containing both calanchi and landslides are common in the sub‐humid badland landscape of central Italy, where field observation identifies a complex pattern of erosive processes associated with a history of uplift, despite which parts of the local landscape appear disconnected. Results reveal that the shape of all S–A curves (plotted using S data binned on log A) is comparable with that described in the literature, although sub‐basins containing calanchi generally plot with higher S values than non‐calanchi ones, except in the ‘fluvial’ section of the plots. Second, when viewed on total data (non‐binned) S–A plots, landslide source area domains and calanchi domains are entirely coincident in all basins, supporting a cause–effect relationship. Additional plotting of the frequency characteristics of the raw data in a new way supports the interpretation that calanchi frequently initiate in landslide scars. In general though, although the S–A plots can contribute to the disentanglement of geomorphological behaviour in some complex erosional landscapes, it became apparent that in this landscape, process domains do not separate out with clarity along the A axis as suggested by theory. Despite this, an alternative, broader‐scale morphoevolutive model can be proposed for the development of within‐landslide calanchi, driven by changes to basin connectivity to the base channel. © 2018 John Wiley & Sons, Ltd.

“…Consequently, they have been used in various fields, such as rescue (e.g., [22][23][24]), active fault mapping (e.g., [25][26][27]), the study of fluvial processes (e.g., [28][29][30]), and the study of landslides (e.g., [31][32][33][34][35]). With high-resolution topography datasets, GIS-based morphometric analysis can also be conducted to derive additional morphological information [36][37][38][39].…”

Badland Erosion and Its Morphometric Features in the Tropical Monsoon Area

Climatically driven processes are important controls on the Earth’s surface and on interactions between the hydrological cycle and erosion in drainage basins. As a result, landscape forms such as hillslope topography can be used as an archive to reconstruct historical climatic conditions. Recent progress in the Structure-from-Motion (SfM) photogrammetric technique allows for the construction of high-resolution, low-cost topography data using remote-controlled unmanned aerial vehicle (UAV) surveys. Here, we present the climatic effects on the hillslope erosion rate that can be obtained from the drainage frequency of hillslopes. We quantify the centimeter-scale accuracy of surveys across 72 badland hillslopes in SE Taiwan, which is a tropical monsoon area with an annual precipitation of over 2 m. Our observations indicate that climatic erosion results in a higher drainage frequency and the number of furrows, instead of drainage density. Additionally, the morphometric slope index (MSI) has a strong positive correlation with erosion and its rate but shows a negative correlation with drainage length and a positive correlation with inclination. This suggests that the erosion pattern is due to gravitational mass wasting instead of hydrological erosion. MSI should always be calculated relying on the normalized slope length and is less applicable to landslide-dominated erosion. We, therefore, suggest that UAV-driven digital elevation models (DEMs) are integrated into erosion mapping to aid in identifying erosion patterns. We highlight the unique opportunity for cross-climate zone comparative studies offered by badland landscapes and differential rainfall patterns, with remote sensing techniques and the morphometric slope index.
