A definition of terms used in this site is provided below

• Envision - The modeling platform used to develop the alternative futures simulations used in this project.  More information on Envision is available here
• Backshore Protection Structure (BPS) -A structure, such as a rock revetment, built to control erosion by armoring the dune face. These structures dissipate wave energy and prevent further recession of the backshore.
• Erosion-A general term applied to the wearing away and movement of earth materials, in this case sand and sediment, by gravity, wind, water, and ice.
• Flooding-An overflow of water onto lands that are normally above sea level. Flooding can be produced by storm surge, sea level rise, and the effects of climatological phenomena such as the El Niño Southern Oscillation (ENSO).
• Scenario Narratives -Scenarios do not predict future changes, but describe future potential conditions in a manner that supports decision-making under conditions of uncertainty. Scenarios are used to develop and test decisions under a rangeof plausible futures
• Sea Level Rise (SLR) -Increases in the height of mean sea surface elevation. In this application, SLR takes regional factors (e.g., vertical land motions, ocean dynamics, and cryosphere and fingerprinting effects) affecting sea level in Oregon into account
• Significant Wave Height (SWH) -A statistical measure of wave height, related to the average of the 1/3 highest waves. This measurement was intended to express the wave height estimated by a “trained observer.
• Total Water Level (TWL)-The combination of the water level (tides and non-tidal residuals) with waves. In Oregon, the wave-induced component can account for as much as 60% of the elevation of the total water level.
• Urban Growth Boundary (UGB) -A regional boundary set in attempt to control urban sprawl.
