Ecological Degradation of Streams
• Sustainable improvement of stream ecological conditions
requires integration of hydrological, chemical, biological, and
geomorphological processes across a range of scales (from
watershed to in-stream biogeochemical processes)
• How do we integrate microbiological, chemical &
hydrologic/transport processes?
– Nonlinear relations: Fluid flow-microbial-chemical variables
– Linear processes with non-linear drivers (heterogeneities in
physical, chemical, and biological processes)
• We propose a wireless network with embedded networked
sensing
– multi-scale,
– spatially-dense,
– real-time, and
– event driven observations
Test Bed: Minnehaha Creek,
MN
Hypothesis
Water quality in urban streams is controlled by
the mean and variance of stormwater residence
