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...

despite of suitable geological and climatic conditions for forming and evolution of alluvial fans and importance of this landform as soil and water resources in arid regions, there are limited studies about this landform in iran. in the present study, evolution and pedogenic development of geomorphic surfaces of an alluvial fan in eastern isfahan were studied by using remote sensing, field and ...

This study investigates the effects of vegetation patch patterns on morphological evolution alluvial river channels at reach-scale. For this, a new two-dimensional numerical biomorphodynamic model has been developed using Telemac-Mascaret system. Considering newest development in topic, bedload transport are included by extending Einstein's parameters for sediment formula. The was subsequently ...

This paper investigates the paleoenvironmental evolution of a core extracted in middle sector Tinto River estuary, SW Spain, one most polluted areas world due to mining over thousands years (>4 kyr BP) and recent industrial discharges. includes alluvial sands (>6.4 cal BP), bioclastic silts deposited subtidal intertidal channels during after Holocene transgression maximum (6.4-4.3 sedimen...

abstract geomorphology and soil genesis and its development are closely related. besides, soil-landscape studies provide a better understanding of soil forming processes. the objectives of the present research include soil genesis studies, micromorphology and clay mineralogy of soils related to geomorphic surfaces in jiroft area. soil temperature and moisture regimes of the area are hyperthermi...

Radiocarbon dating of late Quaternary deposits and shorelines of Lake Mojave and cation-ratio numerical age dating of stone pavements (Dorn. 1984) on the adjacent Soda Mountains piedmont provide age constraints for alluvial and eolian deposits. These deposits are associated with climatically controlled stands of Lake Mojave during the past 15.000 yr. Six alluvial fan units and three eolian stra...

Dust samples collected annually for 5 years from 55 sites in southern Nevada and California provide the first regional source of information on modem rates of dust deposition, grain size, and mineralogical and chemical composition relative to climate and to type and lithology of dust source. The average silt and clay flux (rate of deposition) in southern Nevada and southeastern California range...
