Rapid Assessment Protocol • Culmination of > 10 years Shoreline Research and Outreach • Addresses key request from end-users – “Do these work?” • Baseline for Change Assessment
Ecological and Structural Performance • Ecological – Several variables known to be linked to ecological functions in the Hudson River. • Physical – – Stability of “built” structures – Assess the physical forces on the site
Purpose • Track change over time – yearly observations, after event. • Today – Introduce / interpret variables – Put Demonstration sites in context
Protocol Applied at 5 Sites Nutten Hook Summer 2017 Sust Shore Demonstration sites All Observations Collected Coxsackie in one low tide cycle Sites are quite variable Esopus Meadows Foundry Dock Beczak CURB
Stability • Asset Displacement – • Key Elevations – • Erosion -
Forces • GIS layer of Modelled currents/waves, ice observations • Wave attenuation by sill if present • Plaster casts for erosive forces
ECOLOGICAL VARIABLES • Wrack – Indicator, Organic Matter and Habitat • Wood – Indicator, Habitat • Vegetation – Indicator, Habitat and Structural element
CONTEXT (Tie to Strayer Presentation) • Earlier Hudson Shoreline Ecology Data Sets – Multiple shore types, built and natural – Identified range in ecological variables – Found some “predictors” of ecological function • Slope • Roughness
SLOPE Gentle R2 = 55% P < 0.01 Steep
