Characterizing Spatial and Temporal Variability of Hydrological and Biogeochemical Processes across Scales

Session ID#: 80700

Session Description:
Hydrobiogeochemical (HBGC) processes are often spatially discrete (hotspots) and temporally restricted (hot moments) due to variability in controlling factors like energy inputs, lithologic characteristics, microbial composition, vegetation, etc. Although this scale-dependence of HBGC processes accounts for a high percentage of nutrient cycling, the ability to identify and incorporate them into numerical simulation models remains a significant challenge. This session invites contributions that identify spatial and temporal patterns in biogeochemical variables, implement such variability in process-based models, and/or document the extent that hot spots/moments influence larger-scale system functioning. This session will focus on exchanging ideas on (1) new techniques for identifying HBGC hotspots and hot moments across scales, (2) understanding the governing controls such as, soil-landscape features, flux-inputs, vegetation characteristics that lead to this emergent behavior, (3) incorporating this spatio-temporal variability in models and/or designing scale-aware parameterization, and (4) quantifying the significance of  incorporating this emergent behavior in reactive transport models.
