Marine Energy Effects on the Environment, Sandia National Laboratories, Albuquerque, New Mexico The U.S. Department of Energy’s mission to develop a robust and safe renewable energy infrastructure requires that stakeholders, permitting agencies, and developers understand and mitigate negative effects to the environment. To support that understanding, worked to develop application methods for numerical models that simulate the effect wave and current energy conversion technologies have on their surrounding environment. This has resulted in the development of the Spatial Environmental Assessment Tool to quantify and compare potential power production and risk to the environment.

Coastal Resilience

Sea Level Rise Vulnerability Assessment for Stanford’s Hopkins Marine Station, Pacific Grove, California Numerical modeling lead for a sea level rise vulnerability assessment and adaptation plan for Stanford University’s coastal marine laboratory in Pacific Grove, California. This included supporting the coastal engineering team to model and visualize the extent of wave run-up and coastal erosion, accounting for all building, utility, and biological resources and assets across the 11-acre campus. The run-up and erosion modeling was used to conduct a site-specific level of hazards analysis detailing locations of building and utility sensitivities, and the ways dynamic wave pressures and flood depths could impact these assets. Working with Stanford’s Land, Buildings & Real Estate Department, the team identified a series of sea level rise trigger points and developed an adaptation plan involving short- to long-term strategies.

Sea Level Rise and Vulnerability Assessment for South Padre Island, Texas Numerical modeling lead for a sea level rise, wave run-up, and coastal erosion vulnerability assessment along the coastline of South Padre Island. South Padre Island is a narrow, low-relief barrier island along the south Texas coastline that is impacted frequently by erosive winter storm events and infrequent, but extremely damaging, major hurricanes. The assessment phase involved modeling of future potential impacts due to storms combined with sea level rise. Advanced state-of-the-science modeling was utilized, incorporating measured data from wave buoys to simulate waves along the South Padre Island coastline. This study identified predicted impacts of potential coastal change during a range of storm events under future sea level rise scenarios.

Arctic Coastal Erosion: Modeling and Experimentation, North Slope, Alaska Permafrost along Alaska’s north slope comprises 34 percent of the world’s coastlines. Due to heightened wave activity and temperatures, erosion of the permafrost coastline can exceed 10 m/year and is increasing. Current tools for predicting coastal evolution were developed for temperate areas and non-cohesive sediments, limiting their applicability for permafrost coastlines. To develop adaptation strategies for Arctic infrastructure, accurate methods of predicting these discrete events are needed. Teamed with Sandia National Laboratories, the U.S. Geological Survey, University of Alaska Fairbanks, and University of Texas at Austin, Integral led the development of a numerical modeling system to predict hydrodynamics and waves along Arctic coastline. These hydrodynamic predictions were integrated into a terrestrial processes model used to quantify rates of permanent coastal land loss.
