<h2><b>NP3.5 Scales and scaling in surface and subsurface hydrology</b></h2>
<p>Convener: Marco Marani <br>Co-Conveners: Joao de Lima, Witek Krajewski, M.
Gebremichael, Remko Uijlenhoet<br>The issue of scales and nonlinear physical,
chemical and biological processes is of fundamental importance in hydrology. The
questions of how such processes are organized in space and time across a range
of scales, how different processes interact at different scales, and how
observations at one scale are related to those at another have profound
implications for our ability to predict hydrologic cycle components. Answering
these questions, in view of the undergoing environmental changes at all scales,
requires concerted theoretical, modeling, and experimental efforts. Such efforts
are undertaken by research groups around the world. This session is devoted to
reporting research results on all aspects of scales and scaling in both
groundwater and surface hydrology, including hydrometeorology and ecohydrology.
Scaling research topics on hydrologic processes on scales ranging from
laboratory to hillslope to small (e.g. urban) basins to regions and continents
to entire Earth are all appropriate. Contributions of both scientific and
engineering aspects of scaling research and applications are welcome. It is
Conveners intention to approach this complex issue in a broad way in order to
encompass different scales both in time and space including interactions between
nonlinear hydrologic processes at different scales. Posters focusing on a
specific scale, either for surface or groundwater processes and their modeling
and observations, are also welcome. </p>
