I spend the first week of December at AGU in Washington DC. The NSF-funded critical zone group had 6 posters on data collected in our urban stream network. My former postdoc, Ryan Frederiks, presented on noisy data in urban systems when using hydrograph separation to try to identify groundwater inputs. Josh Caplan, colleague in Landscape Horticulture at Temple presented on plant uptake of salts.
My poster was on issues with using impervious cover as a metric for stream response. This figure illustrates that correlations with IC are depending on the very low and very high IC data. In the middle range, the correlation is non-existent, which makes IC not very useful for most urban systems.
It was a busy, crowded week as typical for AGU!
