Abstract

As global climate changes, regional weather events become more extreme and erratic. We use remote sensing methods to quantify the changes locally. This study combines Structure from Motion(SfM) surveying techniques with airborne Light Detection and Ranging (LiDAR) data collected in 2016 to determine changes in river morphology. The survey takes place in a controlled river channel within Boise city limits on the Boise River. By overlaying rasters from both techniques we can determine channel change. After record levels of rainfall in early 2017 led to high water levels through the spring, we expect to see distinct changes in a surveyed area of the river. This data can then be processed to determine the volume of eroded material. A sample plot not affected by the river will also be surveyed to examine the accuracy of SfM with LiDAR and the effect of riparian vegetation on the survey quality.
