## Project Summary

The NOPP-Hurricane Coastal Impacts (NHCI) program is composed of five tasks and ten teams, with each team focusing on a specific task based on the team's expertise and the resources they have available. The five tasks are detailed below and information about each team is located in the Teams page.

**Task 0**

Provide deterministic, ensemble, and nowcast model support for use by collaborative teams.

**Task 1** Develop quantitative Digital Elevation Models (DEM) from satellite remote sensing techniques for use before, during and after storms.

**Task 2** Conduct remote sensing of coastline impacts from landfalling hurricanes.

**Task 3** Develop methods to rapidly deploy wave and water level sensors for validation and assimilation data.

**Task 4** Set up models for the entire US Gulf Coast, Florida Coast and Eastern Seaboard with sufficient nesting capabilities for skillful forecasting, as informed by prior tasks.

## The five NHCI tasks in detail

### Task 0

**Provide deterministic, ensemble, and nowcasts model support for use by collaborative teams.**

#### **Year 1**

Provide  a hindcast of Hurricane Michael from COAMPS-TC1

#### **Years 2-4**

Summer/Fall - Provide hurricane track and intensity predictions for 3 landfalling hurricanes

Winter – Reanalyze the three hurricanes following best-track and intensity.

#### **Outcome**

Apples-to-apples forcing for Task 4 analysis

### Task 2

**Conduct remote sensing of coastline impacts from landfalling hurricanes.**

#### **Year 1**

Develop quantitative capabilities in satellite remote sensing for building a ground-truth DEM

#### **Years 2-4**

Obtain quantitative geophysical measurements during the three storms

#### **Outcome**

Observation data for hindcast comparison and possible assimilation into model forecasts

### Task 3

**Develop methods to rapidly deploy wave and water level sensors for validation and assimilation data.**

#### **Year 1**

Develop methods for rapid deployments of offshore and nearshore wave, wind, and water level observations

#### **Years 2-4**

Collect in situ measurements including offshore waves, as well as offshore and inland water levels

#### **Outcome**

Observation data for Task 4 assimilation prior to landfall and ground truth evaluations afterward

### Task 4

**Set up models for the entire US Gulf Coast, Florida Coast and Eastern Seaboard with sufficient nesting capabilities for skillful forecasting, as informed by prior tasks.**

#### **Year 1**

Model development and Hurricane Michael hindcast study

#### **Years 2-4**

Forecasting of wave, surge, sediment transport (erosion and accretion above and below mean sea level), structure interaction and damage enabled by boundary conditions and observational data from Tasks 0-3

#### **Outcome**

Improved forecasting skill of hurricane coastal impacts.
