Resection has multiple meanings:
resectioning involves enlarging the cross-section of a river channel by deepening or widening the river to increase its hydraulic efficiency. This allows a larger discharge to be contained within the channel. Dredging is used to remove surplus sediment from the river bed and vegetation clearance is used to remove it from the bed and banks.
Orientation
Resection is a method of orientation (direction or position finding) using a compass and topographic map.
Resectioning involves enlarging the cross-section of a river channel by deepening or widening the river to increase its hydraulic efficiency. This allows a larger discharge to be contained within the channel. Dredging is used to remove surplus sediment from the river bed and vegetation clearance is used to remove it from the bed and banks.
It may also involve the regrading of the long profile - smoothing undulations in bed topography, and filling in riffles.
Traditional resectioning was trapezoidal, rectangular or triangular - but now there is increasing emphasis on producing more natural geometries.
