H14D:
Characterizing Spatial and Temporal Variability of Hydrological and Biogeochemical Processes Across Scales I


Submit an Abstract to this Session


Session ID#: 62155

Session Description:
Biogeochemical processes are often spatially discrete (hotspots) and temporally restricted (hot moments) due to variability in controlling factors like hydrologic fluxes, lithologic characteristics, microbial composition, vegetation, etc. Although this scale-dependence of biogeochemical processes accounts for a high percentage of nutrient cycling, the ability to identify and incorporate them into reactive transport models remains a significant challenge. This session invites contributions that identify spatial and temporal patterns in biogeochemical variables, implement such variability in reactive transport 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 biogeochemical hotspots and hot moments across scales, (2) understanding the governing controls such as, soil-landscape features, flux-inputs, vegetation characteristics that leads to this emergent behavior, (3) incorporating this spatio-temporal variability in models and/or designing scale-aware parameterizations, and (4) quantifying the significance of  incorporating this emergent behavior in reactive transport models.
