See those "pinch points"? The river will eventually form meander cutoffs, and become a sinuous system rather than a meandering river. This will lead to localized increases in channel slope (due to a reduction in channel length), and therefore increased local velocities, shear stress, and sediment transport.

Rivers are always seeking equilibrium, so the channel will actually start to move (bank erosion / lateral shifting) to reduce that localized slope and bring things back in order.

Rivers are so fucking cool.

As someone who doesn't know river lingo, can you translate this?

River tangled. River no like tangle. River cut off curvy bits. Connects back to make a less curvy path of least resistance.

curvy bits eventually meet and water go straight, make lakes.
