Growth Laws for Channel Networks
Hosted by Vivek Sharma
Abstract:
Channelized drainage networks transport water and sediment over length scales ranging from centimeters to thousands of kilometers. Relevant flows occur not only on the surface, but also in the subsurface. In the latter case, groundwater “seepage” flows that exit the subsurface at channel heads can drive channel growth. Seepage flows have been suggested as an explanation of enigmatic channelization patterns on Earth and Mars and are thought to play a significant role in the erosion of levees. In this talk I will explore how networks of seepage-driven channels grow.
