H118:
Structural variability and its impact on water flow and storage


Possible Alternate Format: If this session is allocated an oral session, the convener can choose to have lightning style presentations that are quicker and more focused than a traditional session. Learn more


Session ID#: 23421

Session Description:
The impact of structural variability poses major challenges for understanding water flow and solute transport processes across the hydrological cycle. Plant roots and earthworms can create rapid passages through the upper soil even during unsaturated conditions. Cracks and weathering alter the hydrological behavior in the bedrock and at the soil-bedrock interface. As a result of structural variability, fast and slow flow and storage dynamics may exist beside each other, even at unsaturated conditions. This session solicits abstracts that provide new insights in hydrologic processes that are affected by structural variability, compare those processes across varying terrains and scales, and analyze existing methods, theory and modeling approaches.
