New grant from UW-NPS Research Station to examine channel change along the Snake River in Grand Teton National Park
We have just been awarded a new grant from the University of Wyoming-National Park Service Research Station's Small Grants Program for a study entitled "Mapping Channel Change and Habitat Dynamics along the Snake River from a Time Series of Remotely Sensed Data." This investigation will use image data to be acquired in the summer of 2015 through the National Agricultural Imagery Program (NAIP) to extend our analysis of river morphodynamics. With the new NAIP data, we will have annual coverage from 2009-2015 for the Snake River from Jackson Lake to Moose. These images, along with field measurements each year beginning in 2010, will provide insight on the more local, shorter-term processes that influence the river's overall sediment budget, particularly at tributary confluences that introduce sediment to the main stem. Another objective of this new grant will be to map the occurrence of in-stream large wood and assess the influence of log jams on patterns and rates of channel change. Field work for this study will commence in June 2015.
