These lateral-accretion bedding are formed by the migration of attached and point bars
, and they are erosively based, because of the migration of the basal part of the channel.
The key units relevant to this study were emergent alluvial point bars
and (in decreasing order of water depth) forced pool, pool, chute, recirculation, run, riffle entrance, glide, backwater and riffle (see glossary, page 70).
We found that you need enough vegetation on the outer bank to slow down erosion and let the bars grow on the inner bank; otherwise, the stream cuts through the point bars
and creates a braided river," Braudrick said.
The western extent of this channel can only be mapped on the full stack reflection slice showing accreted meander point bars
or early migrating meander loops lying west of the arcuate fault zone.
Most dredged material disposal areas are now located on erosional point bars
, typically at a bend in the river so high flow redistributes sediments downriver.
The river meanders actively, cutting into banks on the outside of bends and depositing sediment on point bars
at the tips of elongating meander loops (Kalliola et al.
There are a number of favorable structures for the deposition of gold and diamonds such as dykes scour pools and point bars
identified on our Cuyuni property.
A number of favourable structures for the deposition of gold and diamonds, such as dykes, scour pools and point bars
, have been identified within the Cuyuni River Project.
Within the area of interest, the Hackberry is stratigraphically trapped as a series of point bars
When the music reaches a certain frequency, point bars
will emanate from the center of the game.
