Beyond precipitation: physiographic gradients dictate the relative importance of environmental drivers on savanna vegetation
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
Background: Understanding the drivers of large-scale vegetation change is critical to managing landscapes and key to
predicting how projected climate and land use changes will affect regional vegetation patterns. This ...
Combined spatial and temporal effects of environmental controls on long-term monthly NDVI in the Southern Africa savanna
(MDPI, 2013)
Artículo / Artikulua,
Deconstructing the drivers of large-scale vegetation change is critical to predicting and managing projected climate and land use changes that will affect regional vegetation cover in degraded or threated ecosystems. We ...
Comparison between capacitive and microstructured optical fiber soil moisture sensors
(MDPI, 2018)
Artículo / Artikulua,
Soil moisture content has always been an important parameter to control because it is a
deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection.
In this work, a discrete sensor ...
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 ...
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 ...
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 ...
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 ...
Watering or buffering? Runoff and sediment pollution control from furrow irrigated fields in arid environments
(Elsevier, 2015)
Artículo / Artikulua,
Surface irrigated agriculture in arid and semi-arid regions contributes to downstream environmental degradation. Changes in irrigation system operational scenarios (ISOS) can represent an economic alternative to reduce ...
