Assessment and modeling of the generation and transport of water and solutes in representative watersheds of Navarre (Spain): toward an optimal and sustainable agrarian activity
El objetivo general de esta tesis es ampliar la base de conocimiento sobre la dinámica de los sólidos disueltos totales, con especial atención a los nutrientes más extendidos en los sistemas agrícolas (N, y en menor medida ... -
Assessment of the main factors affecting the dynamics of nutrients in two rainfed cereal watersheds
Nutrient dynamics and factors that control nutrient exports were observed in two watersheds, namely Latxaga and La Tejería, with similar climatic and management characteristics throughout 10 years (2007–2016). Similar ... -
Avances en el conocimiento de la erosión por flujos concentrados y su óptima evaluación en campo: un enfoque experimental
La presente tesis tiene como propósito (i) ampliar el conocimiento sobre la interrelación entre la hidráulica y la morfología de canales de erosión a través de una detallada caracterización y análisis de la macro-rugosidad ... -
Dissolved solids and suspended sediment dynamics from five small agricultural watersheds in Navarre, Spain: a 10-year study
Dissolved solids (DS) and suspended sediment (SS) loads are considered relevant environmental problems. They are related to a wide range of on-site and off-site impacts, such as soil erosion or salinization of water bodies. ... -
Effects of agricultural activities on water quality: catchment-scale modeling of nutrient pollution and management in cultivated lands, case studies of northern spain and southeastern sweden
La intensificación de la agricultura para satisfacer la creciente demanda de alimentos y la dinámica climática cambiante requiere una gestión sostenible de los recursos de la tierra y el agua. Esta tesis doctoral examina ... -
Irrigation implementation promotes increases in salinity and nitrate concentration in the lower reaches of the Cidacos River (Navarre, Spain)
The shift from rainfed to irrigated agriculture is associated with a change in the fertilization rates due to increases in expected production and the fact of growing more N demanding crops. In addition, the circulation ... -
Measuring, modelling and managing gully erosion at large scales: a state of the art
Soil erosion is generally recognized as the dominant process of land degradation. The formation and expansion of gullies is often a highly significant process of soil erosion. However, our ability to assess and simulate ... -
Relationship of weather types on the seasonal and spatial variability of rainfall, runoff, and sediment yield in the western Mediterranean basin
Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is ...
