definition
A fascine is a bundle of sticks or brushwood used in construction, generally to strengthen an earthen structure, fill ditches, or make a path across uneven or wet terrain. Live fascines are bundles of live branches intended to grow and produce roots. They can be placed in shallow trenches on a stream bank to reduce erosion across the bank and increase soil stability. The rooted branches protect the toe of the stream bank from erosion and improve infiltration. Properly placed, the bundles can also trap debris and sediment. Live fascines can also be used to reinforce slopes and increase drainage and infiltration. They are installed perpendicular to the slope in dug trenches or in existing gullies and rills.

Enhancement of flood protection durability, reclamation of landconditions
The optimum spacing depends on the steepness of the slope, usually 4 m intervals for slopes of less than 30° and 2 m intervals for slopes of 30–45°. They are most effective on soft cut slopes or slopes with consolidated debris.(Shrestha, A. B. et. al., 2012, p. 26)
