Grain-scale monitoring of fluvial morphology is important for the evaluation of river system dynamics. Significant progress in remote sensing and computer performance allows rapid high-resolution data acquisition, however, applications in fluvial environments remain challenging. Even in a controlled environment, such as a laboratory, the extensive acquisition workflow is prone to the propagatio...

Widespread Amazonian-aged fluvial channels have been mapped proximal to Lyot crater, a ~225 km diameter impact basin in the northern lowlands of Mars. Comparable in area to some Noachian/Hesperian fluvial systems, their morphology differs, being dominated by broad, shallow braided channels. Using new developments in the study of cratering, water inventory, and climate history, we assess eight d...

1. ABSTRACT This abstract presents an approach for oil spill environmental sensitivity evaluation in landscape modifications within half hydrological cycle over the wetland in the Western Amazonia, Brazil, using JERS-1 SAR seasonal classified images and a fuzzy logic method. A pair of multitseasonal set of JERS-1 images (1995-low water season and 1996-high water season) obtained in The Global R...

The alluvial flood plains of lowland Britain contain thick sequences of fine-grained sediment that result from the deposition of suspended sediment during flood events. These environments constitute important storage zones for a wide range of sediment-associated nutrients and con­ taminants and many of the geochemical properties of the deposited sediment are strongly related to particle size. R...

Uranium-thorium dating of speleothems from two caves in the Junee-Florentine karst, Tasmania, provides some age constraints for associated clastic sediments including coarse dolerite-rich fluvial gravels, which underlie the three oldest dated speleothems. The results suggest minimum ages of 15 ± 5 ka, ~325 ka and >350 ka (two dates) for the gravels, implying that they are considerably older tha...

Extended Abstract 1Introduction Estimating correct volume of sediment in a fluvial system is one of the most important issues in water engineering, river engineering, water resources, facilities, structures, water and environmental projects and programs for the development of them. The bed load transfers by saltation and suspension forms according to the sediment particle size. The sediment loa...

Introduction: The Hypanis fan-shaped deposit in Xanthe Terra has been interpreted by many to be a late Noachian aged delta along the dichotomy boundary [15]. The putative delta was a compelling candidate landing site for the future Mars 2020 and ExoMars rover missions as it was positioned at the edge of an open basin, could have been an ideal environment for biosignature formation, concentratio...
