How vegetation alters waves and current, and the feedbacks to environmental system function

Vegetation provides a wide range of ecosystem services valued at over 4 trillion dollars per year. Seagrasses, salt marshes, and mangroves, damp storm surge and waves, mitigate anthropogenic nutrient loads, and provide important habitat and blue carbon reservoirs. The conservation and restoration of these landscapes has become the center-point of nature-based solutions for coastal protection and carbon mitigation. This seminar will summarize basic concepts in vegetation hydrodynamics, focusing on flexible meadows of seagrass, for which the bending of plants in response to fluid motion (called reconfiguration) plays an important role in setting the drag. Scaling laws are developed to describe the damping of currents, turbulence and waves as a function of plant morphology, flexibility, and shoot density. The feedbacks from plant-flow interaction to sediment transport and carbon sequestration are also discussed.


Sponsored by the Department of Mechanical Engineering and the JHU Student Section and the Baltimore Section of the American Society of Mechanical Engineers.

RISE@APL Poster and Information Session 2018
Oct 10 @ 4:00 pm – 6:00 pm
RISE@APL Poster and Information Session 2018 @ Glass Pavilion

The Research Internships in Science and Engineering (RISE@APL) program allows highly qualified undergraduate and graduate students from the Whiting School of Engineering and the Krieger School of Arts and Sciences the opportunity to conduct research at the Johns Hopkins Applied Physics Laboratory.

At this poster and information session, RISE@APL Scholars will present their research findings, while representatives from APL and Johns Hopkins Engineering will be available to answer students’ questions about the application and selection process.
