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 ...
Evaluation of soil moisture estimation techniques based on Sentinel-1 observations over wheat fields
(Elsevier, 2023)
Artículo / Artikulua,
Soil moisture (SM) is a key variable in agriculture and its monitoring is essential. SM determines the amount of
water available to plants, having a direct impact on the development of crops, on the forecasting of crop ...
Effects of innovative long-term soil and crop management on topsoil properties of a mediterranean soil based on detailed water retention curves
(European Geosciences Union, 2022)
Artículo / Artikulua,
The effectiveness of conservation agriculture (CA) and other soil management strategies implying a
reduction of tillage has been shown to be site-dependent (crop, clime and soil), and thus any new soil and crop
management ...
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 ...
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 R tools for downloading MODIS images and their use in urban growth analysis of the city of Tarija (Bolivia)
(MDPI, 2022)
Artículo / Artikulua,
The aim of this study was to compare the available tools in R for downloading and processing Moderate Resolution Imaging Spectroradiometer (MODIS) data, specifically the Enhanced
Vegetation Index (EVI) product. The R tools ...
Determinación de las curvas IDF en Igueldo-San Sebastián. Comparación de diferentes métodos
(Universidad Politécnica de Valencia, 2018)
info:eu-repo/semantics/article,
Las curvas de intensidad-duración-frecuencia (IDF) son una herramienta fundamental en ingeniería hidrológica. Se ha partido de la serie de precipitación de 88 años registrada cada diez minutos en la estación meteorológica ...
The role of ethnic characteristics in the effect of income shocks on African conflict
(Elsevier, 2021)
info:eu-repo/semantics/article,
This paper disentangles the ethnic drivers of the effect of food-related income shocks on African conflict employing geo-localized information. We consider diversity and political ethnic variables and several conflict ...
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. ...
