Evacuation areas based upon worst case hurricane surge scenarios for category 1 through 4 hurricanes striking the coast of Rhode Island. Hurricane surge values were developed by the National Hurricane Center using the SLOSH (Sea Lake and Overland Surge from Hurricanes) Model. This Surge Inundation layer was created by the U.S. Army Corps of Engineers, New England District. Using ArcInfo's Grid extension, bare earth elevation data from several sources was subtracted from the worst-case hurricane surge values to determine which areas could be expected to be inundated. This layer was developed to assist emergency management officials in hurricane preparedness and operations. This statewide dataset compiled from county-based datasets originally developed and published by the US Army Corps of Engineers.

This submission includes all the data to support an LCOE baseline assessment for the Resolute Marine Energy (RME) Surge WEC device.

This project successfully developed methods for numerical modeling of sediment transport phenomena around rigid objects resting on or near the ocean floor. These techniques were validated with physical testing using actual sediment in a large wave tank. These methods can be applied to any nearshore structure, including wave energy devices, surge devices, and hinged flap systems. These techniques can be used to economically iterate on device geometries, lowering the cost to refine designs and reducing time to market. The key takeaway for this project was that the most cost-effective method to reduce sediment transport impact is to avoid it altogether. By elevating device structures lightly off the seabed, sediment particles will flow under and around, ebbing and flowing naturally. This allows sediment scour and accretion to follow natural equalization processes without hydrodynamic acceleration or deceleration effects of artificial structures. This submission includes the final technical report for this DOE project. The objective of this project was to develop a set of analysis tools (hydrodynamics and structural models providing inputs into a sediment model), and use those tools to identify and refine the optimal device geometry for the Delos-Reyes Morrow Pressure Device (DMP), commercialized by M3 Wave LLC as "APEX."

Contains the Reference Model 5 (RM5) spreadsheets with the cost breakdown structure (CBS) for the levelized cost of energy (LCOE) calculations for a single RM5 device and multiple unit arrays. These spreadsheets are contained within an XLSX file and a spreadsheet editor such as Microsoft Excel is needed to open the file. This data was generated upon completion of the project on September 30, 2014. The Reference Model Project (RMP), sponsored by the U.S. Department of Energy (DOE), was a partnered effort to develop open-source MHK point designs as reference models (RMs) to benchmark MHK technology performance and costs, and an open-source methodology for design and analysis of MHK technologies, including models for estimating their capital costs, operational costs, and levelized costs of energy. The point designs also served as open-source test articles for university researchers and commercial technology developers. The RMP project team, led by Sandia National Laboratories (SNL), included a partnership between DOE, three national laboratories, including the National Renewable Energy Laboratory (NREL), Pacific Northwest National Laboratory (PNNL), and Oak Ridge National Laboratory (ORNL), the Applied Research Laboratory of Penn State University, and Re Vision Consulting. Reference Model 5 (RM5) is a type of floating, oscillating surge wave energy converter (OSWEC) that utilizes the surge motion of waves to generate electrical power. The reference wave energy resource for RM5 was measurement data from a National Data Buoy Center (NDBC) buoy near Eureka, in Humboldt County, California. The flap was designed to rotate against the supporting frame to convert wave energy into electrical power from the relative rotational motion induced by incoming waves. The RM5 design is rated at 360 kilowatts (kW), uses a flap of 25 m in width and 19 m in height (16 m in draft), and the distance from the top of the water surface piercing flap to the mean water surface (freeboard) is 1.5 m. The flap is connected to a shaft with a 3-m diameter that rotates against the supporting frame. The supporting frame is assumed to have an outer diameter of 2 m, and the total length of the device structure is 45 m. The RM5 OSWEC was designed for deep-water deployment, at depths between 50 m and 100 m, and was tension-moored to the seabed.

Vector point data representing Rhode Island storm surge heights resulting from Superstorm Sandy in October of 2012. This information provides insight into the extent of surge height during the storm, and may be useful in predicting how similar storms will affect the Rhode Island coastline during future storm events. These data may also be used as a comparison tool in conjunction with tidal data such as Mean High High Water (MHHW). Represent locations of the inland storm surge extents during the duration of Superstorm Sandy in Rhode Island over October 29th and 30th 2012.
