Major Research Activities
|
1. Earth - Atmosphere Interactions, Mechanisms of gas flux in the subsurface

|
2. Drying porous media, Evaporation, Salt precipitation
Figure 2: Evaporation front and salt precipitation in heterogeneous porous media (after Nachshon et al., 2011 WRR) |
|
3. Fracture flow
Figure 3: Conceptual schematics of instability and dynamic processes in fractures crossing the upper vadose zone (after Weisbrod et al., 2002 JCH) |
|
4. Colloid and colloid facilitated transport in fractured and porous media
Figure 4: A cartoon of colloid-facilitated transport (Modified from McCarthy et al., 1998) |
|
5. Contaminant transport in the subsurface
Figure 5: Various tools are being developed and used to explore the fate of contaminants (e.g., salts, Cr, PPCPs, explosives, Perchlorate and more) in both streams, unsaturated and the saturated zone, in situ. |

6. Managed Aquifer Recharge (MAR)/ Soil Aquifer Treatment (SAT) optimization
Figure 6: Monitoring equipment being installed at one of the SAT infiltration basins (Shafdan, Israel). |

7. Dynamic processes along the Dead Sea shore
Figure 7: Dynamic dissolution of salt cores taken from coreholes drilled along the Dead Sea shore. CT analysis was used to define the dynamic pattern of dissolution channels being developed as water salinity changed (Weisbrod et al., 2012 GRL). |
