H43Q:
Environmental Vadose Zone Hydrology I

Submit an Abstract to this Session



Session ID#: 34364

Session Description:
The vadose zone provides an important linkage between the Earth's surface and groundwater, and influences a wide range of critically-important environmental hydrologic phenomena such as recharge, ET, and subsurface transport. However, many vadose zone dynamics and hydrologic controls are still poorly understood due to the random and structural heterogeneities that exist across scales in both time and space, the complexities and non-linearities that occur within and between processes, and the difficulties associated with quantifying and monitoring these processes. We solicit poster presentations that advances our understanding of dynamic hydrologic and (bio)geochemical processes in the vadose zone. Topics may include but are not limited to: unsaturated and multiphase flow and transport, effects of heterogeneity including preferential flow, climate change-induced vadose zone processes, measurement or monitoring techniques applicable to the vadose zone, and uncertainty in vadose zone flow and transport prediction.
