Current research projects

The current research of Dr. Lubczynski concentrates on hydrogeological and ecohydrological problems of water limited environments. He currently carries on field investigations in: Sardon Catchment in Spain, in the Madagascar Island, in the Central Kalahari in Botswana and in the Bali Island in Indonesia.

1. Assessment of subsurface fluxes, surface-groundwater interactions and impact of climate change in hardrocks of Sardon Catchment (Spain) - the Sardon Catchment (~80 km2) is a research test area and education site of the Water Resources Department of ITC. The catchment is equipped in hydrological monitoring network since 1994. The network focuses on monitoring of groundwater (water table, temperature and EC/Cl), unsaturated zone profiles (soil moisture, matric potential, temperature and EC/Cl), microclimatic data (2 towers) and sap flow of trees (applying TDP and HFD methods). The Sardon Catchment was selected as research study area because of:

• Mediterranean climate, typical for water limited environments;
• remote, natural environment with negligible human impact; therefore particularly suitable for research on the impact of climate change on water resources;
• typical savanna type of vegetation with only two different, sparsely distributed oak tree species (deciduous Quercus pyrenaica and evergreen Quercus ilex), i.e. vegetation typical for semiarid and/or arid conditions;
• uniform geology - weathered and fractured granite, representative for hard rock areas;
• shallow groundwater table, allowing for relatively easy installation of piezometers and for monitoring of groundwater;
• logistical convenience – EU country, friendly people, proximity of academic town of Salamanca providing opportunity for scientific collaborations.

The research objectives of the current Sardon research are formulated in the four PhD studies and subsequent papers of the PhD students of Dr Lubczynski: Alain Pascal Frances, Leonardo Reyes Acosta, Enrico Balugani and Tanvir Hassan. The "Sardon" research group of Dr Lubczynski is focused on quantitative assessment of subsurface water fluxes, on applying new approaches in data acquisition, on data integration and on modeling. We believe that realistic description of physical processes requires acquisition of reliable data in extensive spatial and temporal context. In that respect we propose various novel data acquisition and data integration techniques such as: automated field monitoring, non-invasive hydrogeophysical methods such as magnetic resonance sounding, electric resistivity tomography, ground penetrating radar and electromagnetic methods and also satellite and airborne remote sensing. Various applications of these methods are published in papers as listed below. For data integration and hydrological modelling of subsurface fluxes we proposed a new, open-source MODFLOW coupling called MARMITES-MODFLOW that improves handling of subsurface evapotranspiration, particularly of water uptakes by trees. Besides, in our group we also use standard, public domain, integrated hydrological models such as GSFLOW(Hassan et al. 2014).
