SSS6.1: Measurement and modeling of soil processes in different scales

 Dear colleagues,

We would like to draw your attention to the a new session that will be held at the 2022 EGU General Assembly in Vienna (Austria) from 3 to 8 April 2022:

SSS6.1: Measurement and modeling of soil processes in different scales

Water, energy, and solute transport in the vadose zone occur in a variety of scales. How the processes occurring at the small scale control and constrain the large scale responses is a long-standing challenge in vadose zone hydrology. Description of several processes such as evaporation, infiltration, soil-root-water interactions as well as soil characteristics such as conductivity and mechanical impedance rely on small scale measurement which are used to model processes occurring at scales much larger than the measurement scales. The utilization of advanced experimental and modelling tools are required to close the hierarchical gap present in different scales. Within this context, the focus of this session is on measurement or modeling approaches to parametrize or conceptualize soil physical, thermal, hydraulic, and mechanical properties across different spatial and temporal scales and resolutions from the size of a pore to the sample or field scale. We invite contributions related to:
- Measuring soil physical and chemical properties in the lab, field, or watershed utilizing a variety of tools ranging from micro-scale imaging to local measurement by soil sensors, drowns, radars, remote sensing, etc.
- Analytical, empirical, statistical, or numerical modeling approaches that link soil processes across scales, upscaling and downscaling experiences to tackle heterogeneity challenges for the description of vadose zone processes such as evaporation, infiltration, land-atmosphere interactions, and subsurface mass and energy fluxes.
- Modeling or measurement campaigns concerning the spatiotemporal changes of vadose zone properties at different scales induced naturally or by human activities such as freezing-thawing circles, climate change, heavy agricultural machinery, and agricultural practices.

The abstract submission deadline is 12 January 2022, 13:00 CET

Looking forward to receive your contribution,
