This model is being used for ongoing research into controls on erosion, deposition, and yield rate changes in post-wildfire debris flows. This primarily contributes to a PhD dissertation, but is being applied by other researchers to their work as well. +

Standard flow routing and uniform sampling principles are used to govern the processes of this model. +
Resolution constrains are primarily imposed by the resolution of change detection being used. It is recommended that channel reach spacing is kept at least >5x the resolution of the change detection data. +

If not available, change detection may nee … If not available, change detection may need to be completed in advance of model use. The model includes a tool to convert .LAS files to .TIF if point cloud change detection is used. A flow-routed debris flow path shapefile is the only other item which may not be readily accessible. DEMs can be found on OpenTopography or similar and should not require pre-processing software.hould not require pre-processing software. +
This tool estimates the volume of material … This tool estimates the volume of material eroded and deposited at user-defined increments along a debris flow channel. This model performs best in the analysis of channelized, highly erosive flows, and does not capture processes such as minor riling or sheetwash laden with sediment well, as these processes are typically below the limits of change detection used in the application. change detection used in the application. +
Temporal resolution constrains are again primarily associated with the temporal resolution of the change detection data used (span between pre- and post- data, number of storms and/or debris flow events contributing to the volumes being estimated). +

This model generates investigation polygon … This model generates investigation polygons which are used to estimate and store incremental erosion and deposition volumes along the path of a debris flow at user-defined resolution. The user will need: 1) a .LAS or .TIF of topographic change, 2) a DEM of the AOI, and 3) a shapefile (polyline) of the debris flow path of interest. Each incremental volume is georeferenced and stored within a shapefile attribute associated with a catchment area and distance from outlet for analysis.rea and distance from outlet for analysis. +
