The gravel-sand transition and grain size gap in river bed sediments
网页2021年11月1日 This is the only abrupt grain size reduction in the fluvial system. Interestingly, there is a general absence of river bed surfaces characterized by median grain sizes between ~1 and 5 mm (Lamb and Venditti, 2016), a range in grain size which we refer to as the ‘grain size gap’. At larger scales, the gravel-sand transition denotes a
