Field surveys of channel width w and drainage area A in bedrock channel reaches reveal relationships where w 5 cA, similar to the classic hydraulic geometry of alluvial channels. Data from five mountain channel networks support the assumption used in many landscape evolution models that an alluvial hydraulic geometry relationship where b 5 0.3–0.5 holds for bedrock channel systems. Although the...

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...

River bottom sediments and soils were collected from the industrialized Thur River basin (north-eastern France) to assess mercury contamination. The regional geochemical background level of total mercury was evaluated to calculate mercury contamination factors (Fc) in soils and river bottom sediments. Our estimate of the mean background mercury levels in river sediments and soils, not affected ...

Local surface water and stormflow were infiltrated intermittently from a 40-ha basin between September 2003 and September 2007 to determine the feasibility of recharging alluvial aquifers pumped for public supply, near Stockton, California. Infiltration of water produced a pressure response that propagated through unconsolidated alluvial-fan deposits to 125 m below land surface (bls) in 5 d and...

In this study, poultry manure compost and organic fertilizer were added to soils derived from basalt, granite, and river alluvial deposits for use as soil parent materials. Following incubation periods of 30 or 60 days at 25 °C, the physical and chemical properties and adsorption characteristics of the soils were studied. The results indicated that the application of poultry manure compost or o...

Introduction: We have studied a terraced fan deposit centered at 15.0° S, 299.7° E within one of the troughs of Coprates Catena in order to investigate the role that water may have played in its formation. Only a handful of these unique terraced fan deposits have been identified on Mars [1-4], although their small sizes make them difficult to identify with the current data sets. The few fan dep...

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...

In recent decades, China has been experiencing rapid economic development, population growth and urbanization. These processes have stressed the shortages of water resources in China, especially in the arid regions of northwestern China. In order to sustain the expanding cropland, people increased groundwater exploitation in these regions. The purpose of this study was to quantitatively analyze...

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...

Field mapping was carried out on Bima sandstone from Dumne and its environs with the aim to understand geology determine paleoenvironment of deposition. The integrated (outcrop study granulometric pebble morphometric) studies were used achieve this aim. Based outcrop studies, nine (9) lithofacies identified proximal alluvial fan facies mid-fan braided river: massive, matrix-supported, gravel-do...
