Small-scale variability in surface moisture on a fine-grained beach : implications for modeling aeolian transport

Auteur(s) et Affiliation(s)



Description :
Small-scale variations in surface moisture content were measured on a fine-grained beach using a Delta-T Theta probe. The resulting data set was used to examine the implications of small-scale variability for estimating aeolian transport potential. Field experiments were conducted at Padre Island National Seashore, Texas. Both very wet and very dry grid data sets exhibited little internal variability in moisture content, while intermediate moisture contents were associated with higher levels of variability. Cumulative distribution functions were calculated to model the relative proportions of beach surface area expected to be above or below specified threshold moisture levels to allow aeolian transport. Results and discussion about the aeolian transport potential in the beach area.
