Rivers moving mountains will be the subject of the Thursday, April 11, Speaker Series from the Lower Nehalem Watershed Council, featuring special guest Dr. Stephen Lancaster.
In a talk titled “It Takes a Lot of Guts: The Slow Digestion of Mountain Ranges by Stream Networks,” Lancaster will discuss how rivers and streams erode away mountains, deposit sediment and move across their floodplains.
The talk will be of interest to anyone who recreates on any river, landowners who have property on a river, land managers and anyone interested in how coastal watersheds have changed and will change over time.
Lancaster, an associate professor of Geology and Geophysics at OSU, has a lot of experience with this topic. His PhD research focused on creating models of river meandering and how they influence models of how landscapes change. Additionally, he worked with the Oregon Coastal Landscape Analysis and Modeling Study.
The presentation will start at 7 pm at Pine Grove Community House, 225 Laneda Avenue in Manzanita, preceded at 6 pm by a meeting of Lower Nehalem Watershed Council.
