Rapid Assessment Protocol

Culmination of > 10 years Shoreline Research

and Outreach

Addresses key request from end-users – “Do

these work?”

Baseline for Change Assessment

SLIDE 2

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

SLIDE 3

Purpose

Track change over time – yearly observations,

after event.

Today

– Introduce / interpret variables – Put Demonstration sites in context

SLIDE 4

Protocol Applied at 5 Sites Summer 2017

Nutten Hook Coxsackie Esopus Meadows Foundry Dock Beczak CURB

Sust Shore Demonstration sites All Observations Collected in one low tide cycle Sites are quite variable

SLIDE 5

Stability

Asset Displacement –
Key Elevations –
Erosion -

SLIDE 6

Forces

GIS layer of Modelled currents/waves, ice
bservations
Wave attenuation by sill if present
Plaster casts for erosive forces

SLIDE 7

ECOLOGICAL VARIABLES

Wrack – Indicator, Organic Matter

and Habitat

Wood – Indicator, Habitat
Vegetation – Indicator, Habitat and

Structural element

SLIDE 8

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

R2 = 55% P < 0.01

Steep Gentle

HETEROGENEITY

R2 = 25% P = 0.03
