The windings of rivers have long fascinated their human observers. For example, Aboriginal legend explains the sinuous pattern of the modern Finke River (Fig. 1) as the creation of the immense and powerful Rainbow Serpent as he emerged during the Dreamtime from deep waterholes. Recently in PNAS (1), a new theory for the general origin of such sinuous flow patterns was published, which follows f...

17 Abstract—This study outlines a method for generating an 18 automated micro-landform map of an alluvial plain for 19 further flood hazard assessment by combining Shuttle Radar 20 Topographic Mission Digital Elevation Model (SRTM DEM) 21 and satellite images. Average elevation and channel features 22 extracted from DEM are associated with soil moist condition 23 (thresholds of Modified Normali...

Samples of a naturally bioreduced, U-contaminated alluvial sediment were characterized with various microscopic and spectroscopic techniques and wet chemical extraction methods. The objective was to investigate U association and interaction with minerals of the sediment. Bioreduced sediment comprises approximately 10% of an alluvial aquifer adjacent to the Colorado River, in Rifle, CO, that was...

A cyclical pattern can be observed in the central sector of the Guadix Basin (southern Spain) in the Late Pliocene-Quaternary alluvial fan deposits prograding into its axial valley. A climatic significance has been attributed to this cyclicity on the basis of sedimentological and preliminary isotopic studies. The progradation phases of the alluvial fans are here attributed to more arid time int...

The processes of sediment transport, scour, and deposition in an alluvial channel are extremely complex. Theoretical developments of sediment transport functions for different flow and sediment conditions are based on assumptions of different degrees of complexity [1]. Some of the simplified assumptions are based on idealized laboratory conditions that may not be true for the much more complica...

The Atacama Desert has experienced a long and protracted period of hyperaridity that has resulted in what may be the most unusual biome on Earth, but the duration of this aridity is poorly constrained. We reconstructed aspects of the fl uvial and geochemical history of this region using integrated landscape features (alluvial fans, hillslope soils, soil chemistry, river profi les) in the southe...

The Nitra river belongs to the most contaminated rivers in the Slovakia due the previous intensive industrial activity of several enterprises located in its neighborhood. The aim of the study was to estimate the risk of contamination of riverside sediments as well as alluvial soil in vicinity of Nitra river by dangerous heavy metals. Pseudototal content of risk metals (Pb and Cd) including all ...
