In recent years a large number of scaling laws in geomorphology have been found to be equivalent to only two scaling laws. Recent results on river meanders indicate that there may be only one universal scaling law, implying all the others. Moreover, recent theoretical results on turbulent flow in rivers indicate that turbulent flow is the source of the universal scaling of river basins and river networks.
These results provide a key to the understanding of the fundamental structure of the surface of the earth, that layers of complexity such as tectonic uplift, earthquake rifts and the action of glaciers can then be added to. It provides a way of quantifying transport of water, sediments and chemicals over the surface and exchanges of dissolved chemicals between the water and the atmosphere. In particular this seems to provide a method to quantify the transfer of carbon dioxide from rivers to the atmosphere. This workshop will explore why and how this transport due to turbulent flow takes place and is optimal.
Other transport such as transport of magma in volcanoes will also be covered and how similar ideas can be used to identify and quantify transport in social networks and economics.
