Abstract
Ocean waves interact with the environment in many ways. They transport
energy and mass, and the resultant sea-surface roughness defines the
drag coefficients that transmits wind energy to the ocean (Drennan et
al., 2003). Through erosion and deposition, waves change the shape and
landscape of coastal areas. Storm surge waves can cause flood damage in
coastal areas. Recent studies revealed that wetlands are sensitive to
the wave condition, which determines the retreat or growth of coastal
ecosystems (Green and Coco, 2007; Mariotti and Fagherazzi 2010). Human
activities rely on the condition of waves to conduct marine activities
such as fishing, shipping, oil extraction, and offshore constructions.
Thus, it is important to understand ocean waves to improve earth system
modeling, protect the coastline, predict storm surge, preserve coastal
ecosystems, and enhance the offshore business. This project will explore
the application of synthetic aperture radar (SAR) imagery to predict
significant wave height near the coast. High-frequency (HF) radar data
of the ocean (aka CODAR) was used as ground truth data set to calibrate
and validate the wave height estimator. Off-shore wind data was also
included. The developed code will enhance the current capability to
process the satellite data and create a new platform to monitor the
coastal environment. The collected data will help further our
understanding of the wave spectrum in a coastal environment and the data
can support other research in the related topics, e.g. the interaction
of waves and ice sheets, wetlands, shorelines, wind farm and
aquaculture.
