Effect of initial step height on headcut development in upland concentrated flows
Bennett, S.J.; Casalí Sarasíbar, Javier (American Geophysical UnionWiley, 2001)
Artículo / Artikulua
Experiments were conducted to examine the effect of initial step height on growth, development, and upstream migration of headcuts in concentrated flows typical of rills, crop furrows, and ephemeral gullies. In a laboratory ... -
