Alluvial fans are an important land resource in the Qinghai-Tibet Plateau with expansion of human activities. However, factors alluvial fan development poorly understood. According to our previous investigation and research, approximately 826 exist Lhasa River Basin (LRB). The main purpose this work is identify influencing by using machine learning. A index (Di) was created combining its area, ...

Abstract On September 28, 2018, an Mw 7.5 Palu earthquake triggered massive landslides upstream, followed by 24 debris flood events that spread to 15 villages in Sigi from 2018 December 2021. Debris flow and flash floods on alluvial fans inundated lowland communities, causing severe property destruction structural damage bridges roadways resulting estimated 900 damaged houses. Understanding the...

Slip rates of the right-lateral Owens Valley Fault lie at the center of an ongoing debate over the rheology and mechanics of lithospheric deformation in eastern California. Slip rates determined from paleoseismic records of surface rupture yield Late Pleistocene – Holocene rates of < 1mm/yr to ~2 mm/yr. The decadal velocity field across the valley, however, approaches ~6 mm/yr of right-lateral ...

The integration of sedimentological and structural data in the western end of the Ripoll syncline allows a clearer understanding of the palaeogeography of the area between the oblique termination of the Pedraforca thrust sheet and the frontal Vallfogona thrust during middle Eocene times. In this region, a 2.5-km thick clastic succession corresponding to the Bellmunt and Milany sequences infille...

Rivers around the world are being regulated by dams to accommodate the needs of a rapidly growing global population. These regulatory efforts usually oppose the natural tendency of rivers to flood, move sediment, and migrate. Although an economic benefit, river regulation has come at unforeseen and unevaluated cumulative ecological costs. Historic and contemporary approaches to remedy environme...

The Carboneras fault is one of three principal Cenozoic strike-slip faults in the Betic Cordillera of southeastern Spain. In this study, we characterize the paleoseismic history of the Carboneras fault by examining the evidence for lateral offset of 85-180 ka ‘Iyrrhenian marine terraces, by dating the left-lateral stream-channel offsets in La Serrata, and by postulating a late Holocene coastal ...

Xinjiang serves as a hub for trans-Eurasian exchange. The hominids are supposed to be greatly influenced by the environment due fragile ecology and arid climate. As territory with most significant complex geomorphic units in Inner Asia, features diverse spectrum of forms, including mountains, basins, deserts, river valleys, oases. This paper presents systematic summary locations 127 Bronze Age ...

Pliocene (?)—early Pleistocene shallow marine deposits, varying from gravel to sand clay, characterize the southernmost sector of Valdichiana Basin, between Orte and Città della Pieve, across Tuscany, Umbria Latium (Central Italy). Facies associations, referring evolution a river-fed coast, with sensible facies heteropy, sub-environment articulation, both alongshore, have been recently describe...

Numerous sedimentary fans on Mars have been studied to better understand the early martian hydrological system. Of particular interest is estimate duration of fluvial activity from alluvial fan size by dividing deposit volume bankfull sediment flux. However, such a calculation requires an intermittency factor—a parameter relating discharge channel-filling (bankfull) floods long-term mean discha...
