“…Control by the North Anatolian Fault System (NAFS) of the tectonic development of basins in the eastern sector is evident in Quaternary. Indeed, results of analysis indicated that the alluvial fan and fan catchment morphology in the Erzincan pull-apart basin and Yeşilırmak River Basin, both situated within the eastern section of the NAFZ (Figure 3b), are mainly controlled by the continuing tectonic activity of the NAFZ (Hubert-Ferrari et al, 2002;Sarp, 2015). Results of a specific morphotectonic study on the east part of NAFZ indicate that the geologically-constrained mean Neogene slip rate of 6.5 mm/yr (over 13 Myr) was followed by a higher Holocene slip rate of about 20 mm/yr (Hubert-Ferrari et al, 2002).…”

The Yeşilırmak River Basin is located in the North Anatolian Fault Zone (NAFZ) which is one of the fault zones with intense seismic activity in Turkey. The Almus Fault is a segment of the North Anatolian Fault (NAF). This study aims to reveal the effect of the Almus Fault on the drainage development and morphotectonic evolution of the upper catchment of the Yeşilırmak River Basin and the relative tectonic activity of the fault. Morphometric indices such as, stream length gradient index (SL), mountain front sinuosity (Smf) and fan entrenchment (E) indicate that the downward of the sub-basins is tectonically more active than the upward which is ascribed to the tectonic activities along the Almus Fault. The Smf value is 1.4 at the west and decreases to 1.1 at the mouth of the sub-basins on the east. This indicates that the tectonic activity along the Almus fault in the study area increases from west to east and the uplift rate in the northern part is higher than the southern part of the study area. Development of the drainage network started during Pliocene due to differential uplift and a humid climate then developed under tectonic forcing during Quaternary.

“…Landform evolution of subcatchments is closely related to the different amounts of crustal uplifts (Lifton and Chase 1992;Gürbüz et al 2015;Sarp 2015;Partabian et al 2016), therefore, the spatial variation of subcatchments' landform evolution is characterized by periodic replacement. However, the landform evolution of catchment has not only been controlled by the overall tectonic framework, Figure 12.…”

Neotectonics has changed the coupled process of endogenic and exogenic geological dynamics, which mold the modern landform. Geomorphologic analysis is essential for identifying and understanding the tectonic activity and indicates the responsive mechanism of the landform to tectonic activity. At first, this research reconstructed the twisted Shanpen period planation surface, computed the valley floor width-to-height ratio of Sancha river and extracted the cross sections marking the river terraces to analyze the characteristics of the neotectonics. And then, the relation between neotectonic movement and landform development was analyzed by dividing the landform types. At last, the spatial variation of landform evolution was analyzed by extracting the Hypsometric Integral of sub-catchments. The Sancha river catchment's neotectonic movement presents the tilt-lift of earth's crust from NW to SE, which is characterized by the posthumous activity of Yanshan tectonic deformation. The spatial distribution of river terraces indicates that Sancha river catchment has experienced at least four intermittent uplifts and the fault blocks at both the sides of Liuzhi-Zhijin basement fault have differentially uplifted since the late Pleistocene. As the resurgence of Liuzhi-Zhijin basement fault, the Sancha river catchment was broken into two relative independent landform units. The spatial variations of the landform types near the Sancha river and the sub-catchments' landform evolution are characterized by periodic replacement. The styles of geological structure have controlled the development of landform far away from the Sancha River and influenced the landform evolution. The posthumous activities of the secondary structure have resulted in the spatial variation of sub-catchments' landform evolution, which presents periodic replacement with local exceptions. The present study suggests that spatial variations of the development and evolution of modern landform of Sancha River catchment owe their genesis to the interplay between the hydrodynamic force and tectonic activity in the neotectonic period. Likewise, the application of geomorphic indicators also provides a new way to assess the regional crustal stability.

“…There are many sizes of alluvial fans in LRB, and the distribution of quantity and area is uniformed. The formation and development of alluvial fans base the catchment characteristics, tectonics and climate (Sarp, 2015). The size of alluvial fans is major determined by the characteristics of catchment (Mather et al, 2016).…”

“…Regional tectonic and climate effect the deposit process and geomorphology of alluvial fans (Bull, 1977). Tectonic forces effect the morphology by controlling the scale of accommodation space and organizational types of deposit material (Sarp, 2015). The increasing aridity in the Late Pleniglacial result that the alluvial fan is small-scale in central Europe, and the scale is more in the humid times (Sarp, 2015).…”

The land that is suitable for settlement or live is shortage in Lhasa River Basin (LRB). Alluvial fan is a candidate resource to suitable land in this situation. However, the basic information of alluvial fans, for example its distribution and land-use types, is little known. In this study, Google earth, ArcGIS and visual interpretation were used to get the outlines, areas, quantity and distribution of alluvial fans. Meanwhile, the land use, the distance from alluvial fans to roads, places (town and village) and rivers (including stream) are analyzed. The results show that there are 826 alluvial fans in LRB and the total area is 1166.03 km². The quantity of alluvial fans with area between 0.1 km2 and 1 km2 is 517, which is dominated in all. The quantity of alluvial fans is concentrated in the east of LRB, but that area is mainly distributed in the west. The area of Grassland is the largest in all land use types which is account for 68.70% of alluvial fans. Although cropland area is accounted by 2.16% of alluvial fans, it is accounted by 18.98% of the LRB's cropland area. The quantity of alluvial fans within in 5km distance to tertiary road, village, and river (including stream) are accounted of 93.70%, 53.63% and 77.38% respectively. Therefore, alluvial fans have played an import role in LRB, and may have huge utilization potential in the future.
