The 35th Annual Alexander Graham Christie Lecture @ 210 Hodson Hall

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.


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

HEMI Extreme Arts Exhibit: Symmetry & Fracture (Works by Jenna Frye)
Sep 27 2019 @ 4:30 pm – Jan 10 2020 @ 4:30 pm
HEMI Extreme Arts Exhibit: Symmetry & Fracture (Works by Jenna Frye) @ Milton S. Eisenhower Library, Q Level

HEMI research asks fascinating questions about what happens to materials under extreme conditions. Much of HEMI’s research can’t be perceived without powerful scanning technologies, let alone touched. Touch and perception, however, are both essential to how artists and designers learn and understand the world.

Symmetry and Fracture offers a way to physically connect with the complex research ideas of HEMI labs through hands-on exploration of mineral crystal systems and the grain boundaries of metallic materials.

You are invited to playfully investigate and decide for yourself where or if boundaries lie between art and science.
