In the Delaware Estuary, the tidal range at the mouth of the estuary becomes amplified, resulting in a larger range (difference between high and low tide water surface elevation) further up the estuary.  One way to visualize this effect is via violin plots.  The data below is from the NOAA PORTS system in the Delaware Estuary:

River mile 0 corresponds to the mouth of the estuary, where Delaware Bay meets the Atlantic Ocean.

This effect is especially notable in comparison to the same plot for Chesapeake Bay (where tidal amplification is not observed).

Here's an animated choropleth (graph using colored map shapes) of HUC8 watersheds in the Delaware River Basin showing water yield over a span of 20 days.  The script is fully automated, pulling USGS gage data from NWIS, computing the water yield time series for each subwatershed, and generating the GIF.  I hope also to include this in a Delaware River Basin dashboard.

I developed an R script to retrieve NOAA PORTS data for the Delaware Estuary overnight and generate an animated water surface elevation plot.  I hope to include this in a larger Delaware River Dashboard web page containing graphs of near real-time data.
