Previous studies examined the possibility to estimate the aeolian aerodynamic roughness length from satellites, either from visible/near-infrared observations or from microwave backscattering measurements. Here we compare the potential of the two approaches and propose to merge the two sources of information to benefit from their complementary aspects, i.e. the high spatial resolution of the vi...

The coastal system consists of a sub-aqueous and a sub-aerial zone which can be separated by a border. At this border sediment exchange takes place from one zone to the other. This paper hypothesizes that conditions and therefore sediment exchange at this border are dependent on active profile characteristics. To analyze morphological developments due to combined marine and aeolian processes da...

A progression of induration, erosion, and redeposition of transverse and networked transverse aeolian ridges (TARs) has been documented in the Medusae Fossae Formation (MFF), Mars. Cratered and eroded aeolian bedforms are rarely observed on Mars, indicating that those found in the MFF have been inactive for much longer than those found elsewhere. Indurated TARs are observed to grade into facete...

Abstract This chapter reviews research on solutes by fluvial geomorphologists in the period 1965–2000; growing links with biogeochemical are emphasized later chapter. Brief reference is necessarily made to some from before and after study period. In relation solutes, early sought relate short-term process observations long-term landform evolution. However, very quickly, moved into much more app...

in the present paper various transects perpendicular to iranian makran coasts (chabahar-gawater) were studied using satellite image processing, field observations, sandy shore profiling and grain size analysis to evaluate sedimentology and geomorphology of the area. data revealed that the study area includes exposed rocky shores (52%), sandy shores (40%), and mud flats (8%) sheltered in estuari...

The Conservation Estate, administered by the Department of Conservation (DOC), contains areas of land of undetermined conservation value. These include coastal lands, obtained and managed by the Government of the day for other than conservation purposes. One such purpose was to stabilise coastal sand dunes where drifting sands presented a hazard to adjacent railway lines or roads. The Sand Drif...

In the evolution processes of wind blown sand movement and aeolian geomorphology, it always contains some complex behaviors, for example, the nonlinear character of turbulence and attractors, the stochastic character of wind gust, liftoff and movement of sand, the interaction among wind field, sand movement, electric field in wind blown sand flux and thermal diffusion, multi-scale character fro...

a B B o f J h w w Deposits of a transgressive-phase Lake Bonneville stillstand or scillation are found just below the elevation of the regressivehase Provo shoreline at numerous exposures throughout the onneville basin. Existence of these subProvo shoreline deposits rovides a new explanation for the massive size of Provo deposiional and erosional landforms, which can no longer be explained y a ...
