H11B:
Hydrologic Modeling Across Scales: On the Issue of Scale Dependency

Submit an Abstract to this Session

Session ID#: 6137

Session Description:
Effective identification and modelling of hydrologic systems requires a scale-appropriate representation of the underlying processes. The challenge is that hydrologic processes occur at a range of spatio-temporal scales, which may not be consistent with the scales of available data (observation), and also are often not possible to be simulated within a single modelling platform. This session invites contributions that address different issues of scale for improved hydrologic understanding and modelling. Example contributions include (1) the identification and representation of dominant processes at different scales ranging from small- (e.g., hillslope) to large-scale (e.g., watershed) hydrologic systems, (2) upscaling and downscaling strategies and the transferability of parameters, state variables, observations, etc. across scales, (3) the extent and sources of uncertainties at a particular scale or at different scales, (4) the predictability of hydrologic models at different scales, and (5) the choice of appropriate space-time resolution of the modelling domain across scales.
