Webdevelopment corresponded. In general, the rates of aeolian sand transport were overestimated. The impact of parameters that are related to beach nourishment (viz. grain-size, adaptation length and beach topography), on profile development was evaluated. Grain-size affected the aeolian sand transport rate to the foredunes, and therefore the ... WebMeasured transport rates range from 0.0001 to 0.22 kg m -1 s -1. The results indicate that expressions based on a power relation between the wind speed and the transport rate, …
Web16 de nov. de 2024 · Moisture has a significant influence on the initiation of motion of sand by wind and also on the resulting sand transport rate. While the moisture level is usually very low in sandy desert areas and thus irrelevant there, the aeolian sand transport on sandy beaches or in the context of coastal dune morphodynamics is expected to be … WebThe objectives of this study were (1) to determine the textural parameters influencing the rate of aeolian sand transport and (2) to assess the differences between the rates of …

INTRODUCTION Understanding the spatial variability of sand movement by aeolian transport is important for identifying sources of uncertainty in relating transport rates and wind ... WebThe results showed that aeolian sand transport rates estimated with the developed method were of the same order as those estimated using the existing method for high transport rates, i.e., for transport rates greater than 0.01 kg m−1 s−1. In this study, a new method for the estimation of aeolian sand transport rate was developed; the method …
Web4 de nov. de 2014 · Aeolian sand beds exhibit regular patterns of ripples resulting from the interaction between topography and sediment transport. Their characteristics have been so far related to reptation transport caused by the impacts on the ground of grains entrained by the wind into saltation. By means of direct …
