AnnAGNPS ephemeral gully erosion simulation technology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
Tillage-induced ephemeral gully erosion has been shown to be a significant and sometimes dominant source of sediment within a watershed. An approach has been developed within AnnAGNPS to assess the impact of conservation ... -
Ephemeral gullies: to till or not to till?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
While the perceived magnitude of ephemeral gully erosion may be masked after gullies are repaired, the action of plowing in these channels reduces topsoil thickness and crop productivity over a much wider area than the ... -
Ephemeral gully headcut development and migration in stratified soils
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
The objectives of the current study were: (1) to quantify the effect of an erosion resistant (ER) soil layer placed at various depths within a soil profile on headcut development and migration; and (2) to assess the ... -
Influence of soil structure, pore-water pressure, and tailwater height on headcut migration in upland concentrated flows
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
The primary objective of this study was to determine the impact of soil texture, soil pore-water pressure, and tailwater height on scour hole dimensions, migration rate and sediment yield in headcuts migrating under steady ... -
Turbulent flow within headcut scour holes in rills and gullies
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
The objectives of the present study were to experimentally determine the time-mean turbulent flow characteristics within fixed-bed models of headcut scour holes typical of upland concentrated flows to assess soil erosion ...
