Description:

Abstract:

This dataset comprises four tables containing channel survey cross section data, field observations including channel width and bank material, measured surface water velocity, and alluvial grain size data collected along the North Fork Fortymile River near a man-made meander cutoff called The Kink. The data release also contains eight field photos used to obtain grain size distribution; four photos annotated with measured grains linked to the grain size data table by the fields "meas" and "img."

Purpose:

This dataset was developed for the purpose of analyzing the North Fork Fortymile River adjustment to anthropogenic meander cutoff in 1900 CE.

Browser-based open-source software for image analysis used here to determine grain size distribution in scaled field photos.

Process_Step:

Process_Description:

Field observations - On 14 August 2018, the North Fork Fortymile River's wetted perimeter was surveyed using a cm-precision stadia rod to measure depth at 5-m intervals along a tape measure between coordinates (64.397065, -142.02203) and (64.397596, -142.022886). Scaled photos were collected for grain size analysis of river bank alluvium at (64.397065, -142.02203). Wetted channel widths were collected using a TruPulse 200L laser range finder; at each width measurement site, bank material was noted (alluvium, bedrock, or mix). Surface water velocities were obtained using time trials with a float over a 35 m-long river reach between the channel survey coordinates at the deepest part of the channel.

Process_Date: 20180814

Process_Step:

Process_Description:

Grain size analysis - Using the browser-based ImageJ software, 326 intermediate (shorter of two visible) cobble and pebble axes were measured in four scaled field photos to generate a grain size distribution from which percentile statistics were used to compute sediment transport thresholds and flow resistance.
