At this location, the lidar intensity data are responsive to lithology and distinct lidar facies are identified which correspond to facies types described in measured stratigraphic sections or depositional lobe switching on a distributive fluvial system. In contrast to braided rivers, meandering rivers typically only contain one channel that winds its way across the floodplain as it fluvial sandy point bar facies, (2) low-energy fluvial and microtidally-influenced (upper estuary.

Meandering fluvial systems 1 photo by w w little meandering fluvial system (single channel/mud- or sand- dominated) meandering fluvial systems have a single, relatively deep major channel with a sinuosity of at least 17 (often greater than 25), a low bed/suspended load ratio. Each facies in the scheme exhibits a discrete range in porosity and permeability by which the probable flow characteristics of the sediments can be assessed and has successfully been used by litho-flow facies prediction in an alluvial fan/fluvial system, central north sea a vaughan.
