Description :
Data for arid dune slopes are scarce, owing to the widespread perception that the high infiltrability of sand will reduce runoff. However, runoff is generated on sandy dunes in the Hallamish dune field, western Negev Desert, due to the presence of a thin microbiotic crust. The runoff in turn produces erosion. The goals of this study are to study the relationship between runoff and sediment yield; to study the variability of sediment production from the crest to the base of dune slopes; to compare the sediment production between north- and south-facing dune slopes.
