Field Activity Details for field activity 2012-603-FA

AKA: none

Other ID: 20120319_Elwha_River

Status: Pending

Organization(s): USGS, Pacific Coastal and Marine Science Center, National Park Service

Funding Program(s): Elwha River Restoration Project (NPS) ()

Principal Investigator(s): Andrew Ritchie

Affiliate Investigator(s): Jonathan Warrick, USGS; Amy East, USGS; Andrew Stevens, USGS; Josh Logan, USGS

Information Specialist(s): Andrew Ritchie

Data Type(s): Imagery: Photo

Scientific Purpose/Goals: To collect aerial imagery document Elwha River response to Elwha dam removals at a temporal and spatial scale sufficient to inform theoretical and physical process models and improve understanding of short- and long-term fluvial and coastal responses to large perturbations in base level and sediment inputs

Vehicle(s):

Start Port/Location: Port Angeles, WA

End Port/Location: Port Angeles, WA

Start Date: 2012-03-19

End Date: 2012-03-19

Equipment Used: Structure from Motion - crewed aircraft

Information to be Derived: Per flight: orthoimagery and elevation models (approximately 10cm resolution), recording sediment, wood, water, and vegetation. Across flights: erosion and deposition volumes, changes in grain size, changes in wood location, distribution, abundance, changes in channel form and location, changes in vegetation.

Summary of Activity and Data Gathered: Collected 642 primarily near-nadir images. This was the first deployment of the Elwha Planecam and imagery was suboptimal (blurry) but still able to resolve surfaces and orthoimagery that contribute to understanding of channel state.

Notes: This is the only Elwha Restoration Project flight that contains co-occurring manually-collected imagery from a passenger. These are opportunistic photos that document reservoir and river conditions during the first planecam deployment and they are helpful for alignment using computer vision/structure from motion methods.
