The impact of the deposition of eroded sediments on rill and headcut development and bifurcation (original) (raw)

2016 ASABE International Meeting, 2016

Abstract

The bifurcation of rills is a process that has not been adequately studied or understood. Threshold conditions for rill and headcut bifurcation as well as conditions for sediment deposition in rills and headcuts were studied in rills formed in a sandy loam soil of the Cottenham series in a soil erosion rig. The results from this study were encouraging and elucidate the impact of the deposition of eroded sediments on rill and headcut bifurcation and subsequent rill and headcut development and growth. The results have the potentials of improving rill erosion models if the processes of deposition and bifurcation of rills and headcuts processes are included. Field experimentation of this study is recommended.
