(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaValley bottom gullies are a common feature in rangelands. Although these gullies are found in the bottom of drainage lines, information about the relationship between discharge and gullying is scarce (Crouch, 1990; ... -
Does vegetation cover suppose gully erosion stabilization?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe present research is addressed to study the evolution of vegetation cover on gully sidewalls and its influence on sediment production due to gully erosion and on gully walls’ stabilization. A sample gully system of the ... -

Effect of topography on retreat rate of different gully headcuts in Bardenas Reales area (Navarre, Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaIn Northeast Spain, gullying is a widespread phenomenon. This type of erosion is especially intense in Bardenas Reales (Navarre) where at least two major typical kinds of gully headcut are present. A first group developed ... -
Effectiveness of palm and bamboo geotextiles in reducing concentrated flow erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaRills and gullies, caused by concentrated flow erosion, represent an important sediment source in many environments (Poesen et al., 2003). Studies indicate that vegetation can be very effective in controlling gully ... -
Effects of slope processes and management in gullying
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaMost erosion studies have been typically done in rill and interrill areas because the complexity of gullies and their large size have made their study very difficult. Morgan (1979) and Hudson (1985) define gullies as water ... -
Enzymatic characterization of a monokaryon population of the edible mushroom, Pleurotus ostreatus with a view to genetic improvement
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaIn this work the lignocellulolytic enzymes produced by the edible mushroom Pleurotus ostreatus var. florida were studied. The objective was to know their relationship with the degradation of the biopolymers present in ... -
Ephemeral gullies: to till or not to till?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaWhile 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 erosion research: processes and modeling
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe USDA Natural Resources Conservation Service (NRCS) defines ephemeral gullies as small channels that can be filled in by normal tillage operations only to reform in the same location by subsequent runoff events. Ephemeral ... -
Ephemeral gully headcut development and migration in stratified soils
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe 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 ... -
Erosion processes at the gully scale: observations, quantification and interpretation of field data from the Draix laboratory
