Abstract The sand bodies formed by braided fluvial fan deposits have a certain distinctiveness. They not only the characteristics of facies sandbodies but also follow distribution law alluvial bodies. variation that are present along and perpendicular to channel is relatively complex. Therefore, constraints in modeling process sand–mudstone this type reservoir essential. This study selects seco...

[1] Several dozen distinct alluvial fans, 10 to 40 km long downslope, have been observed in highlands craters. Within a search region between 0 and 30 S, alluvial fan-containing craters were found only between 18 and 29 S, and they all occur at around ±1 km of the MOLA-defined Martian datum. Within the study area they are not randomly distributed but instead form three distinct clusters. Fans t...

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...

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...

Francesco Comiti) had the following objectives included in the Workpackage WP1 "Development of functional relationships for debris flow behaviour" and WP3 " Development of a small basin debris flow impact model": • Organisation of the research team and scientific coordination of activities • Acquisition of existing data on debris flow characteristics in small basins located in the Veneto Region...

The discovery of remarkably rounded pebbles by the rover Curiosity, within an exhumed alluvial fan complex in Gale Crater, presents some of the most compelling evidence yet for sustained fluvial activity on Mars. While rounding is known to result from abrasion by inter-particle collisions, geologic interpretations of sediment shape have been qualitative. Here we show how quantitative informatio...
