Connecting aeolian sediment transport with foredune development
Foredune volume is an important factor for coastal safety and depends on the balance between erosion through wave attack and sediment input via aeolian transport. Dune erosion can be simulated with good accuracy, but predictions of aeolian sediment transport into the foredunes are still difficult to make. As part of a larger project that aims to model foredune development over decades, the goal...
متن کاملAeolian Transport of Coarse Sediment in the Modern Martian Environment
Introduction: Evidence of aeolian sandstone outcrops, migrating sand dunes, and changes in surface albedo changes caused by redistribution of surface dust on Mars demonstrate that aeolian processes have been and continue to be a dominant agent of surface modification [3] [7] [9]. It is known that strong wind events on Mars can be responsible for lifting large amounts of sediment into the atmosp...
متن کاملAeolian sediment transport following wildfire in sagebrush steppe
Wind erosion of soil is an appreciable but unstudied event following fires in cold desert. We examined aeolian transport of sediment for 1 year following fire in semi-arid shrub steppe on loess soils in southern Idaho, USA. Sediment collectors were used to determine horizontal mass transport of soil and saltation sensors and anemometers were used to determine saltation activity (fraction of tim...
متن کاملCommunity Sediment Transport Model
The goal of this project is to produce an open-source model that couples hydrodynamics (circulation and waves), sediment transport, and morphodynamics. The need and value for such a model has been well established by previous NOPP-supported planning efforts (Sherwood et al., 2000; 2002) and the feasibility of the proposed approach has been demonstrated by incorporation of sediment-transport and...
متن کاملDevelopment of a Computer Model for the Prediction of Littoral Sediment Transport Rate
In this paper, longshore sediment transport in littoral zones is investigated. For investigation of sediment transport in the nearshore zone, the effects of waves, currents and topographical conditions of coast are considered. Linear wave theory was used for the investigation of the wave behaviour. Governing equations of littoral current are continuity and momentum ones. For calculating concent...
