Advancing AI-based pan-European groundwater monitoring
The main challenge of pan-European groundwater (GW) monitoring is the sparsity of collated water table depth ( wtd ) observations. The wtd anomaly ( wtd a ) is a measure of the increased wtd due to droughts. Combining long short-term memory (LSTM) networks and transfer learning (TL), we propose an AI-based methodology LSTM-TL to produce reliable wtd a estimates at the European scale in the absence of consistent wtd observational data sets. The co…
Land use change impacts on European heat and drought
Heat and drought are projected to increase globally but may be mitigated or exacerbated by land use/land cover (LULC) change. Here, we show that remote land-atmosphere feedbacks caused by historical European LULC change led to widespread changes in the energy and water balances, drought, and heat. Using a continental-scale bedrock-to-atmosphere model, we find that LULC change following the Soviet Union collapse and European Union formation may ha…
Influence of soil heterogeneity on evapotranspiration under shallow water table conditions
Ensembles of soil column numerical experiments were performed to study the influence of heterogeneity in the saturated hydraulic conductivity on the evapotranspiration or latent heat, LE, under varying water table conditions. In the numerical experiments, a variably saturated groundwater flow model coupled with a land surface model (ParFlow[CLM]) was used. The model was forced at the top with an atmospheric time series from Oklahoma, USA. The het…
