In the Subsurface Hydrology Lab we investigate water flow and solute transport from soils surface down the root zone, the deep unsaturated zone, the water-table area and deep in the aquifer on their way to the perforated interval of a production well.
The research is done at variable spatial scales: from column and pot experiments to field tests and surveys (10-100 m) to regional and aquifer scale analysis (10-100-1000 square kilometers). Usually, the research includes experiment or survey observations that are incorporated in computerized models to enlarge the spectrum of estimations and predictions in time and space.
Some research topics:
Agricultural and environmental impacts of irrigation with water of different characteristics (saline, effluents, desalinated).
Groundwater contamination under agricultural land (nitrate and some micro-contaminants)
Managed Aquifer Recharge with water from different sources (effluents, floods, desalinated etc.) introduced to the subsurface through infiltration ponds, wells drywells.
National soil sensor network, instelation and smart spatial interpolation (near future topic)
