Aeolian Sediment Transport Defined by Grain Size Trends in Part of Haryana

Aeolian deposits occur extensively over the Ambala Older Alluvium in the southern and western part of Haryana. Delineating aeolian sediment transport pattern assists in characterising the aeolian environment and in understanding the evolution of the Thar Desert. Surface exposures of the Late Quaternary stabilised dunes do not exhibit primary structures based on which sediment transport direction can be inferred. The present study of a part of Haryana aims at trend analysis of the first three moment measures of aeolian sediment size distribution to delineate sediment transport pattern.

In the study area trend surface analysis of mean sorting and skewness shows statistically significant trends. Mean size and skewness with a linear trend decreases towards northeast. Sorting increases towards northeast, southeast and southwest. Transport vector' analysis reveals a sediment transport pattern, With northeast and south as the two dominant directions of transportation.
