恭賀!!本系賴悅仁教授獲Nature專題報導

Engineering a dream workspace In my lab, we study the evolution of underwater landscapes. We look at density currents that plunge into an ocean or reservoir, and how sediment and water interact to shape the evolution of deltas, channels and canyons. These kinds of powerful currents occur in extreme events — such as floods or typhoons — and often are too hard to measure from a ship. But we can easily reproduce them here in my lab, using sand and coloured-water flows in a tank. This is a dream workspace for me. But things were very different in 2014, when my master’s student and I were trying to recreate what is essentially a braided river channel on the sea floor. I borrowed space in an old fluid-mechanics lab, and we built a new water tank in a very small corner of this cramped, dark lab. It was challenging. My student redesigned the small...
