COMPUTING EOLIAN SAND TRANSPORT FROM ROUTINE WEATHER DATA

Eolian Sand Transport Monitored by Terrestrial Laser Scanning

Morphodynamic changes at sandy coasts, as are dominant in The Netherlands, are typically monitored at yearly intervals by means of LIDAR. Meanwhile it is recognized that beach morphodynamics is not a regular process but is strongly correlated to meteorological conditions. A time series of 14 terrestrial laser scans of a beach experiment is analyzed, obtained during a time period of 88 hours cha...

Relief Threshold for Eolian Sand Transport on Alluvial Fans

Many arid alluvial-fan terraces downwind from eolian sand sources exhibit an abrupt increase in Av-horizon thickness and sand content below a critical elevation which varies from fan to fan. Above this elevation, sand accumulates locally and is not transported across the fan. Below this elevation both coarse and fine eolian sand from nearby playa and channel sources is readily transported acros...

Sand transport on Mars

Whether the winds of the present Mars are shaping the variety of dune forms observed on the Martian surface has remained an open question that challenged planetary scientists for decades. In order to elucidate this issue, we have studied sand transport and dune formation from two different points of view. The first approach consists of solving the equations of aeolian transport at the level of ...

Geochemical Evidence for an Eolian Sand Dam across the North and South Platte Rivers in Nebraska

Experimental Study of Sand Transport

Experiments were made to determine the effects of sediment size, sediment concentration, and flow velocity on the depositional style of sand-sized particles in a highvelocity surgd. A dimdnsional analysis of the experimental system was performed in an effort to relate the experimental results to deposits from turbidity currents and overwash surges. A large part of each deposit was a result of d...
