“…The geomorphology index is one method of studying active tectonic areas that can give knowledge of relatively rapid levels of active tectonic deformation (Bull and McFadden, 1977;Keller andPinter, 1994, 2002;Faghih, 2015). The research used seven geomorphic index parameters: 1) the ratio of valley floor width to valley height (Vf), 2) drainage basin asymmetry (AF), 3) stream length -gradient index (SL), 4) the basin shape index (BS), 5) mountain front sinuosity (Smf), 6) drainage density (Dd), and 7) the correlated hypsometric integral/hypsometric curve (HI/HC).…”

“…Tectonic geomorphology research is very important to obtain information on neotectonic activity over a large area. The geomorphic index is an indicator that records the response to the latest deformation (neotectonic) processes, so it is widely used to identify active faults (Faghih et al, 2015;Keller and Pinter, 1996;El Ham douni et al, 2008). Landscape and spatial data are very important for studying active tectonics because they can estimate the exact position and historical seismic records (Arrowsmith & Zielke, 2009).…”

“…Landscape and spatial data are very important for studying active tectonics because they can estimate the exact position and historical seismic records (Arrowsmith & Zielke, 2009). Tectonic geomorphological analysis has been widely used as a parameter to measure earthquake hazard in an area (Galadini and Galli, 2000;Faghih et al, 2015;Keller and Pinter, 1996;El Hamdouni et al, 2008;Yudhicara et al, 2017;Hidayat, 2010). Large landforms of the Earth's surface resulting from the competition between uplift and denudation processes were studied (Burbank and Anderson, 2001).…”

Karangsambung, located in Central Java, Indonesia has complex geological conditions of the tectonic evolution of Java Island due to the subduction process of the India-Australia plate with the Eurasian plate in the Cretaceous-Paleocene. The tectonic movements in the subduction zone have resulted in diverse geological structures and rock types and impact the morphological shape of the study area. The level of tectonic activity in the study area can be determined using a tectonic geomorphological approach. A digital elevation model and geographic information systems are used for geomorphic data processing. Geological data observations were also carried out in the form of river terraces. Seven geomorphic index parameters have been calculated to determine the youngest tectonic activity through the relative tectonic activity index (IAT) of the study area: the ratio of the valley floor width to the valley height, the drainage basin asymmetry, the river gradient-length index, the basin shape index, mountain front sinuosity, drainage density, and the hypsometric integral/hypsometric curve. The IAT score is divided into four classes which are class 1 (0%) very highly, class 2 (13%) highly, class 3 (56%) moderately, and class 4 (31%) low. The IAT shows that the research area is categorized as an active tectonic area so that the morphology formed is more influenced by tectonic activity than erosion. Geological data analysis on uplifted and deformed river terrace outcrops shows that the study area is affected by neotectonic activity.

“…It is further necessary to mention that the different geomorphological indices developed based on digital techniques to better understand the behavior of geologic and geomorphologic changes and process. The stream-gradient index, hypsometric integral, valley floor width-valley height ratio, drainage basin shape, drainage basin asymmetry, and mountain-front sinuosity are some examples of the applicable indices for geologic and geomorphologic characterization (Faghih et al, 2015).…”

Watersheds constituted by different geology, geomorphology, climates, land uses, soils, ecological communities, and vegetation covers. The watershed landscapes have established over geologic time while being shaped by patterns of climate, vegetation, and lithology. However, understanding the nexus between watershed health, geology and geomorphology has been less considered and requires a deep knowledge of their spatiotemporal scales of evolution. The current article, therefore, attempts to provide a brief review of geology and geomorphology concepts, importance and applications in watershed health assessment. Additionally, a list of most important geologic and geomorphologic criteria for watershed management and assessment provided as well. The provided information provides useful insights for land managers and decision makers and thus helps in the identification of gaps in knowledge that need to be addressed on a priority basis. It is highly suggested that the future developments in watershed health studies have focused in the direction of the geological and geomorphological process, taking advantage of empirical observations, mathematical and conceptual modeling to attain a quantitative description of real watershed health conditions.

The Zagros Fold‐Thrust Belt is a tectonically active region within the Alpine‐Himalayan orogenic system resulting from ongoing convergence between Afro‐Arabian and Central Iranian plates. The presence of various geomorphic features in this region provides an ideal natural case for identifying deformed landforms resulting from active tectonics. The relative tectonic activity along the Lar and Didehban faults within the Zagros Fold‐Thrust Belt, SW Iran was evaluated using six DEM‐derived geomorphic indices: the stream‐gradient index (SL), drainage basin asymmetry (AF), hypsometric integral (HI), valley floor width‐valley height ratio (Vf), drainage basin shape (Bs), and mountain‐front sinuosity (Smf). These indices were combined to yield the relative active tectonics index (Iat) that allows the variation of tectonic activity along the Lar and Didehban faults to be related to variations in rates of incision, tectonic tilting and uplift. This variable tectonic activity was characterized by different Iat values along the faults. The low to high relative tectonic activity (class 1: 1 < Iat < 1.5, class 2: 1.5 < Iat < 2, class 3: 2 < Iat < 2.5, class 4: 2.5 < Iat) correlates with variable geomorphic features along the faults. The results of this study present an approach for assessing the effects of active tectonics and also for sustainable land use planning over a large area.
