Extended assessment of sprinkler irrigation uniformity in greenhouses using GIS and hydraulic modeling
(MDPI, 2022)
Artículo / Artikulua,
Traditionally, distribution uniformity has been obtained by using rain gauges, which makes it a very expensive process. This paper sought to create a simulation strategy using QGIS and EPANET, both free software, that ...
Evaluation of nitrate soil probes for a more sustainable agriculture
(MDPI, 2022)
Artículo / Artikulua,
Synthetic nitrogen (N) fertilizers and their increased production and utilization have played a great role in increasing crop yield and in meeting the food demands resulting from population growth. Nitrate (NO3−) is the ...
Evaluation of the impact of changing from rainfed to irrigated agriculture in a mediterranean watershed in Spain
(MDPI, 2023)
Artículo / Artikulua,
The conversion of cultivated areas from rainfed to irrigated agriculture alters the watershed’s hydrology and could affect the water quality and quantity. This study examined how streamflow, nitrate load, and nitrate ...
Effects of climate change on streamflow and nitrate pollution in an agricultural mediterranean watershed in northern Spain
(Elsevier, 2023)
Artículo / Artikulua,
Predicting water quality and quantity response to climate change in a watershed is very difficult due to the complexity and uncertainties in estimating and understanding future hydrological conditions. However, hydrological ...
Dissolved solids and suspended sediment dynamics from five small agricultural watersheds in Navarre, Spain: a 10-year study
(Elsevier, 2019)
Artículo / Artikulua,
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. ...
Challenges and progresses in the detailed estimation of sediment export in agricultural watersheds in Navarra (Spain) after two decades of experience
(Elsevier, 2023)
Artículo / Artikulua,
Soil erosion is a very serious environmental problem worldwide, with agriculture considered the main source of sediment in inland waters. In order to determine the extent and importance of soil erosion in the Spanish region ...
Quantification of agricultural best management practices impacts on sediment and phosphorous export in a small catchment in southeastern Sweden
(Elsevier, 2023)
Artículo / Artikulua,
Agricultural activities contribute to water pollution through sediments and nutrient export, negatively affecting water quality and aquatic ecosystems. However, implementing best management practices (BMPs) could help ...
Relationship of weather types on the seasonal and spatial variability of rainfall, runoff, and sediment yield in the western Mediterranean basin
(MDPI, 2020)
info:eu-repo/semantics/article,
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 ...
Assessment of the main factors affecting the dynamics of nutrients in two rainfed cereal watersheds
(Elsevier, 2020)
info:eu-repo/semantics/article,
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 ...
