Lecture on October 24th 2018: Dr. Lawrence Amy (UCD) on "Sediment Transport Processes on Earth, Mars and Titan"

Abstract: Sediment erosion, transport and deposition by rivers and turbidity currents are key processes responsible for shaping large areas of Earth’s natural landscape and seascape. Similar resurfacing of other planetary surfaces by liquids associated with a volatile cycle is also inferred for other planetary bodies in the solar system, including Mars and Titan. This talk will examine suspended-load-dominated flows in a planetary contact and present a new model for equilibrium flow conditions, where sediment erosion equals deposition. Are graded slopes on Mars and Titan similar to those on Earth? When and where: The lecture theatre in the Geological Survey of Ireland, Beggars Bush, Dublin 4 on Wednesday, October 24th, between 6:30 and 7:30 pm. Coffee and biscuits will be available from 5:30 pm. All welcome.
