You might look up a paper by David Rosgen dealing with Cross Vanes and J Hooks. Typically the inside of bend is point bar, and outside of bend higher bank stress and erosion. I have seen them used primarily on small to moderate size rivers. Barbs are sometimes used on larger rivers. If your channel is actively aggrading, the loss in channel capacity may be filling the bankfull channel, forcing floodwaters onto a floodplain prematurely, resulting in sediment accumulations. It is best to try to understand why the river is accumulating excess sediments in the bends, is it natural such As result of landslides, bank erosion, land use changes in watershed, base level shift for some reason, or channel modifications. If the channel has been enlarged in width, the velocity to move sediments may be reduced. You might find some good papers from Corps of Engineers Waterways Experiment Station in Vicksburg, Mississippi (David Derrick). It is best to have a certified hydrologist and/or civil engineer review proposals, as adjusting sediment or flooding in one area may result in effects to other areas upstream or downstream. The certified professionals would carry liability insurance on this type project, that Universities or researchers may not carry In case of damages, lawsuits, etc. Not necessarily my recommendation, but if the deposits are washed high value construction sands, some may consider intermittent dredging these accumulations within the annual sand deposit budget to avoid excess upstream or downstream effects. Removing too much in dredging can cause upstream and downstream effects (G. Mathis Kondolf), so mining or dredging are to be done with caution. Is is best if the river is stable I.e. moving water and sediment narurslly without aggrading or degrading, with a stable bankfull channel with floodplain access. Stabilizing unstable or modified channels and altered watersheds can be challenging. If you have channel morphological, sediment and flood frequency detail, you might try a demo of the Rivermorph or HECRAS software, and you want the channel velocity sufficient during bankfull flow to move any excess sediment accumulations. Velocities necessary to remove point bars will essentially reduce sinuosity and increase bank stress and potential for bank erosion.
Hi dear
I think that's okay: https://acwi.gov/sos/faqs_2017-05-30.pdf, https://acwi.gov/sos/pubs/3rdJFIC/Contents/Posters-Healy.pdf, http://unesdoc.unesco.org/images/0010/001091/109159Eo.pdf and http://unesdoc.unesco.org/images/0025/002587/258795e.pdf
Dear Bahwuk,
It also depends, which types of sediment you mean.
A method for removing / extract bed load sediment is vortex tube.

A lot has been done regarding the Mississippi River. A good starting point is available for download at https://pubs.usgs.gov/circ/1375/C1375.pdf
