The two graphs above show water level height and percent new water that entered each river during Hurricane Sandy on October 30, 2012. The Israel River's peak in water composition lagged behind the peak in water level by 4 hours and 12 minutes. Keene's Beaver Brook, lag time between peaks was only 42 minutes. One hypothesis for this difference is that urban surfaces are less permeable than most of the surfaces which they replace, so rain has less interaction with soils in urban surfaces. Check back for other comparisons. I will be running analysis and posting new graphs.
