Please join us for the upcoming Water Resources Science Seminar. Dr. Jonathan Friedman, USGS, Fort Collins, CO will present “Invasive Tamarisk Documents and Influences Arroyo Evolution along the Rio Puerco, New Mexico” on Wednesday, April 24, from 4 to 5 p.m. in BEXL 328.

About Dr. Friedman: 

Jonathan Friedman is a hydrologist at the USGS Fort Collins Science Center in Colorado. He studies interactions among stream flow, channel change and riparian vegetation across the dry inland western United States. Much of his recent work involves use of riparian tree rings to date floodplain stratigraphy and reconstruct past flow. At the Rio Puerco New Mexico, Jonathan has combined time sequences of lidar, aerial imagery and channel cross sections with analysis of tree rings in invasive tamarisk to document processes of arroyo filling. More recently he has found strongly increased erosion in the Rio Puerco associated with tamarisk removal.

The seminar is free and open to the public. 
We hope to see you there!
