Heidi Nepf, the Donald and Martha Harleman Professor of Civil and Environmental Engineering at the Massachusetts Institute of Technology, will deliver the 35th Annual Alexander Graham Christie Lecture.
The lecture will be held at 3 p.m. on Thursday, May 3, in 210 Hodson Hall.
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.

The annual Nano-Bio Symposium is INBT’s signature event to showcase our multidisciplinary programs and researchers from across the entire University. The event provides an opportunity to hear presentations by leading scholars in the field, both from Hopkins and other institutions. It also offers a unique opportunity to meet and network with faculty and experts to establish new collaborations.
The annual symposium is hosted by INBT and the Physical Science-Oncology Center. This years theme will be Advanced Biomanufacuring and take place at the Homewood campus in the Glass Pavilion.
