Accuracy of methods for field assessment of rill and ephemeral gully erosion
(Elsevier, 2006)
Artículo / Artikulua,
To properly assess soil erosion in agricultural areas, it is necessary to determine precisely the volume of ephemeral gullies and rills in the field by using direct measurement procedures. However, little information is ...
Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain)
(Elsevier, 2018)
Artículo / Artikulua,
The environmental impact of irrigated agriculture on water quality was assessed in Landazuria watershed (Navarre, northeast Spain), a 479.5 ha watershed with 53% of irrigated agricultural land. In the framework of a long-term ...
Gully geometry: what are we measuring?
(European Geosciences UnionCopernicus Publications, 2015)
Artículo / Artikulua,
Much of the research on (ephemeral) gully erosion comprises the determination of the geometry of
these eroded channels, especially their width and depth. This is not a simple task due to uncertainty generated by the wide ...
Evaluation of a gully headcut retreat model using multitemporal aerial photographs and digital elevation models
(American Geophysical UnionWiley, 2013)
info:eu-repo/semantics/article,
A large fraction of soil erosion in temperate climate systems proceeds from gully
headcut growth processes. Nevertheless, headcut retreat is not well understood. Few erosion
models include gully headcut growth processes, ...
Assessment of soil factors controlling ephemeral gully erosion on agricultural fields
(Wiley, 2017)
Artículo / Artikulua,
The soil factor is crucial in controlling and properly modeling the initiation and development of ephemeral gullies (EGs). Usually, EG initiation has been related to various soil properties (i.e. sealing, critical shear ...
Evaluation of 2D models for the prediction of surface depression storage using realistic reference values
(Wiley, 2016)
Artículo / Artikulua,
Depression storage (DS) is the maximum storage of precipitation and runoff in the soil surface at a given slope. The DS is determined by soil roughness that in agricultural soils is largely affected by tillage. The direct ...
Factors controlling sediment export in a small agricultural watershed in Navarre (Spain)
(Elsevier, 2012)
Artículo / Artikulua,
It is recognised that the hydrological and erosion processes in watersheds are very much conditioned by
the (inter)action of a number of variables. This paper covers a 15-year period of studying those factors
that have ...
