Depth dependence of permeability can appear in any geologic setting; however, vertical trends in alluvial gravel deposits are poorly understood because of the high variability of hydraulic conductivity K in monotonic sequences. This paper examines the sensitivity of depth-decaying permeability through heat transport simulation around a river's losing reach in the Toyohira River alluvial fan, Ja...

Geochemical and microbial evidence points to anaerobic oxidation of methane (AOM) likely coupled with bacterial sulfate reduction in the hypersaline groundwater of the Dead Sea (DS) alluvial aquifer. Groundwater was sampled from nine boreholes drilled along the Arugot alluvial fan next to the DS. The groundwater samples were highly saline (up to 6300 mm chlorine), anoxic, and contained methane....

Abstract Endorheic basin brines are of economic significance as sources boron, iodine, magnesium, potassium, sodium sulfate, carbonate, and tungsten, they a major source the critical metal lithium. Although evaporation is primary hypersalinization driver for evaporative water bodies, recent investigations have proposed more novel mechanisms some subsurface brine. This investigation explores sha...

In this study the advantages and importance of a numerical model to predict and monitor the processes governing hydraulic changes alluvial fan river is discussed. For this reason and because of the importance of flow velocity and shear stresses resulting from the erosion of the river, A two-dimensional numerical model to simulate the CCHE2D river changes ranging from Roodan River is used. In th...

Gently sloping surfaces for settlement are scarce in high mountains ranges and they are commonly related to distal parts of alluvial fans where floods hazards can be expected. To understanding the influence of external factors, such as climatic variability and land uses, on the alluvial fan accretion and flooding processes, sedimentology and pollen analysis from local site provide valuable data...

Our understanding of pull-apart basins and their fault systems has been enhanced by analog experiments simulations. However, there scarce interest to compare the faults that bound with surface ruptures during earthquakes. In this study, we investigated effects a 2018 earthquake (Mw 7.5) on basin in Palu–Koro system, Sulawesi Island, Indonesia, using geomorphic observations digital elevation mod...
