| Description |
This data release provides transect locations used for GIS analyses of geomorphic change along the Elwha River, Washington conducted by East and others (2018). The transect locations are represented by fixed points, spaced 250 meters (m) apart, placed along the length of the middle and lower river reaches (excluding the Lake Mills and Lake Aldwell reservoirs) and along a control reach in Geyser Valley, upstream of the historic Elwha and Glines Canyon dam sites. To account for migration of the river channel through time, metrics such as river width were calculated from transects generated within a GIS at each point location, oriented orthogonal to the general river-corridor orientation at the time of image collection.
