Accuracy of methods for field assessment of rill and ephemeral gully erosion
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 ... -
Assessing soil properties controlling interrill erosion: an empirical approach under Mediterranean conditions
Soil erodibility is a complex phenomenon that comprises a number of different soil properties. However, most current (empirical) erodibility indices are based on only a few soil properties. A feasible soil characterization ... -
Assessment of soil factors controlling ephemeral gully erosion on agricultural fields
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 ... -
Beyond precipitation: physiographic gradients dictate the relative importance of environmental drivers on savanna vegetation
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
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
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 ... -
Demonstrating correspondence between decision-support models and dynamics of real-world environmental systems
There are increasing calls to audit decision-support models used for environmental policy to ensure that they correspond with the reality facing policy makers. Modelers can establish correspondence by providing empirical ... -
Evaluation of 2D models for the prediction of surface depression storage using realistic reference values
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
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, ... -
Factors controlling sediment export in a small agricultural watershed in Navarre (Spain)
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 ... -
Gully geometry: what are we measuring?
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 ... -
Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain)
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 ... -
Watering or buffering? Runoff and sediment pollution control from furrow irrigated fields in arid environments
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 ...
