Probabilistic sea level rise flood projections using a localized ocean reference surface.

Projecting sea level rise (SLR) impacts requires defining ocean surface variability as a source of uncertainty. We analyze ocean surface height data from a Regional Ocean Modeling System reanalysis to produce an ocean reference surface (ORS) as a proxy for the local mean higher high water. This method allows incorporation of ocean surface level uncertainty into bathtub modeling and generation of probability-based projections of SLR-induced flooding.

Risk of shoreline hardening and associated beach loss peaks before mid-century: O'ahu, Hawai'i.

Shoreline hardening, which causes beach loss globally, will accelerate with sea level rise (SLR), causing more beach loss if management practices are not changed. To improve beach conservation efforts, current and future shoreline hardening patterns on sandy beaches need deeper analysis. A shoreline change model driven by incremental SLR (0.

Sea-level rise exponentially increases coastal flood frequency.

Sea-level rise will radically redefine the coastline of the 21 century. For many coastal regions, projections of global sea-level rise by the year 2100 (e.g.

Sea-Level Rise Induced Multi-Mechanism Flooding and Contribution to Urban Infrastructure Failure.

Sea-level rise (SLR) induced flooding is often envisioned as solely originating from a direct marine source. This results in alternate sources such as groundwater inundation and storm-drain backflow being overlooked in studies that inform planning. Here a method is developed that identifies flooding extents and infrastructure vulnerabilities that are likely to result from alternate flood sources over coming decades.

Modeling multiple sea level rise stresses reveals up to twice the land at risk compared to strictly passive flooding methods.

Planning community resilience to sea level rise (SLR) requires information about where, when, and how SLR hazards will impact the coastal zone. We augment passive flood mapping (the so-called "bathtub" approach) by simulating physical processes posing recurrent threats to coastal infrastructure, communities, and ecosystems in Hawai'i (including tidally-forced direct marine and groundwater flooding, seasonal wave inundation, and chronic coastal erosion). We find that the "bathtub" approach, alone, ignores 35-54 percent of the total land area exposed to one or more of these hazards, depending on location and SLR scenario.

Effective release of a broad spectrum antibiotic from elastin-like polypeptide-collagen composite.

Preparation of hydrogels that possess an effective antibiotic release profile and better mechanical properties compared to the traditionally used collagen hydrogels has the potential to minimize post-surgical infections and support wound healing. Toward this goal, we prepared elastin-like polypeptide (ELP)-collagen composite hydrogels that displayed a significantly higher elastic modulus compared to the collagen hydrogels. We then characterized the release behavior of the collagen and ELP-collagen hydrogels loaded with varying dosages (1-5% w/w) of a commonly used broad spectrum antibiotic, doxycycline hyclate.
