Introduction: Physical sedimentology experiments using a 39% concentration of sulfuric acid have produced three distinct features, which are similar to features seen on Mars. However, these sedimen-tary features could not be created using pure water in the laboratory. These three features include deeply-incised, narrow channels, cracks that run parallel to the flow direction, and circular depre...

In the upper basin of Guadiana River, especially in sectors drained by its right-bank tributaries, Bullaque and Becea rivers, important concentrations Acheulean Mousterian industries can be found a superficial position. These have provided series containing tens thousands pieces. Deposits stratigraphic position also been identified, related to fluvial terraces Jabalón rivers some tributaries. W...

The lower Calore and middle Volturno valleys preserve stratigraphical morphological evidence tephrostratigraphic markers particularly suitable for reconstructing the long-term geomorphological evolution of central-southern Apennines. Aim our study is to identify main steps Quaternary landscape these valley systems improve knowledge about relationships between fluvial processes tectonics, volcan...

Soils of circumpolar regions store large amounts carbon (C) and are a crucial part the global C cycle. Yet, little is known about distribution soil stocks among geomorphological terrain units glacial valleys in Arctic. Soil nitrogen (N) content for top 100 cm dominant vegetated (i.e., alluvial fans, humid polygons, mesic polygons) at Qarlikturvik Valley, Bylot Island, Canada have been analyzed....

The volume of a debris flow is critical parameter in hazard analysis, yet accurate estimates are often unavailable due to mixing with larger rivers at the downstream end alluvial fans. We describe method calculate flows using depth data collected check dam, Manning friction relation velocity as function depth, and geometry channel cross section. evaluated published set from USGS debris-flow flu...

This research aimed to determine the potential of unconfined aquifer in Gorontalo City based on landform approach. The landforms consist alluvial plains lake deposits, floodplains river fans hills structural fractures reef limestones, pinogu volcanic rocks, and intrusive bone diorite. method used consisted a meteorological approach southern dynamic City. calculation groundwater availability usi...
