Title:Flume Erosion Testing Data of Root-Permeated and Organic Matter Amended Soil Samples Using Three Streambank Boundary Conditions.
Alternate Identifier:DOI PLACE HOLDER
Abstract:
The data published here is expected to accompany one publicly available dissertation (Chapter 6 of dissertation) and one separate journal publication. Once published and available online, the metadata will be updated with the relevant article information. The journal article/dissertation will have additional information regarding the published datasets and the methods used to collect the data. All data collected from these studies, and the accompanying Acoustic Doppler Profiler MATLAB files, are presented here. Journal Article title: Artificial Roots and Soil Microorganisms Increase Soil Resistance to Fluvial Erosion

Data Entities
Data Table Name:
Smith et al_Erosion-Soil-RootData_2022
Description:
Erosion, extracellular polymeric substances, aggregate stability, soil organic carbon, plant root density, and other soil/water property information for all soil samples. The sample was split into three subsections and eroded at a different flow rate in the flume. The erosion rate of each subsample was then averaged and reported here. Each subsample was eroded in a recirculating flume for 10 minutes, or until all of the sample was completely eroded, which ever came first.
Data Table Name:
Smith et al_TestingDate-TurbulenceData_2022
Description:
Erosion testing date, Reynolds stresses, and turbulent kinetic energy for all soil samples. The sample was split into three subsections and turbulence data was collected for each subsample.
Other Name:
ADPData_DespikingLoop_MATLABCode_SDARAv2_From-Ikard2016
Description:
This MATLAB code was created to despike collected ADP data. The loop uses the SDARAv2 function created by Ikard 2016 (Ikard J. Scott (2016). Phase-space Threshold Algorithm for Time Series Data. Researchgate, 10.13140/RG.2.1.1831.4325. Retrieved March 1, 2021).
Other Name:
ADP Velocity Processing Code for All Data
Description:
R code used to process ADP MATLAB files, determine measured velocity, and calculate shear stress/turbulent kinetic energy.
Other Name:
Smithetal_Chapter6_ADP MATLAB Files
Description:
Zip folder containing Acoustic Doppler Profiler (ADP) MATLAB files. The files are organized by block number and contain the original file plus the despiked velocity data.
Other Name:
R code for publication ready plots
Description:
Use this R code to recreate publication ready plots of the generated data.
