Abstract Current databases of soil hydraulic properties (SHPs) have typically been used to develop pedotransfer functions (PTFs) to estimate water retention [θ(h)] assuming a unimodal pore‐size distribution. However, natural soils often show the presence of bimodal to multimodal pore‐size distributions. Here, we used three widely spread databases f...

Water resources observation and modelling are essential to better understand hydrological processes and improve water resource management. However, the reliability of hydrological simulation is strongly controlled by the quality and type of field observations used for the calibration and validation processes. Therefore, it is critical to develop pr...

The inherent biases of different long-term gridded surface soil moisture (SSM) products, unconstrained by the in situ observations, implies different spatio-temporal patterns. In this study, the Random Forest (RF) model was trained to predict SSM from relevant land surface feature variables (i.e., land surface temperature, vegetation indices, soil...

An increasing number of extreme events such as droughts and heavy rainfall exacerbate conflicts between agricultural water uses and other human and environmental demands for water. Natural/Small Water Retention Measures (NSWRMs) can help to mitigate those conflicts, addressing societal challenges such as climate change, biodiversity and food security at the same time. Despite the comprehensive set of water/nutrient retention measures available, knowledge is still lacking on the effectiveness of those measures across various European soil-climatic regions, agricultural systems, scales and especially under changing climate. Thus OPTAIN aims to: (i) identify efficient techniques for the retention and reuse of water and nutrients in small agricultural catchments across Continental, Pannonian and Boreal biogeographical regions of Europe in close cooperation with local actors (ii) select NSWRMs at farm and catchment level and optimize their spatial allocation and combination, based on environmental and economic sustainability indicators. OPTAIN will thus contribute to the achievement of different Sustainable Development Goals and environmental targets formulated in several water- and agriculture-related European Union policies. https://www.optain.eu/ https://cordis.europa.eu/project/id/862756/de Twitter: https://twitter.com/H2020_OPTAIN Facebook: https://www.facebook.com/H2020OPTAIN
