An international team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high.
A high-resolution model of how soil erosion impacts the carbon cycle of a small South Carolina watershed may help explain an apparent imbalance in the world’s carbon budget. Explaining that apparent imbalance is necessary for understanding and predicting the course of global climate change.
It turns out that the sea butterfly (Limacina helicina), a zooplankton snail that lives in cold oceans, lives up to its name. Georgia Institute of Technology researchers went to the Pacific Ocean to scoop up hundreds of the 3-millimeter marine mollusks (called pteropods), and then used high-speed cameras to watch how they move. They found that sea butterflies don’t paddle like most small water animals. Instead, they’re like flying insects, flapping their wings to produce lift and propel them through the water.
Professor Terry Sturm and former Ph.D. student Seung Ho Hong have received a top research award for hydraulic engineering from the American Society of Civil Engineers. Sturm and Hong won for a study on predicting the amount of erosion, or scour, around bridge supports during floods.
Georgakakos explains his work modeling water flows in the Apalachicola-Chattahoochee-Flint river system to CBS46’s Sally Sears. Georgakakos said there’s plenty of water flowing down the Chattahoochee River 85 percent of the time.
A team of scientists led by the School of Civil and Environmental Engineering’s Hermann Fritz has just returned from a four-day reconnaissance mission in South Carolina assessing damage after record-breaking rainfall flooded large swaths of the state. They found several of the dams they inspected failed before they were overtopped by water.
A grassroots group of stakeholders in the three-state battle over water from the Apalachicola, Chattahoochee and Flint rivers released a consensus water management plan for the basin May 13, thanks in good measure to work by Professor Aris Georgakakos and his team.
The day after Christmas in 2004, a massive earthquake shook the ocean floor, sending a tsunami rippling through the Indian Ocean. When that surge reached the shore — from Thailand to Africa — it left more than 250,000 people missing or dead in 12 countries. Millions more lost their homes. Hermann Fritz, a renowned tsunami expert, did extensive research after the disaster, and he recently talked about the event a decade later.
