Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Yield Rate Threshold Locator Model type Tool Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D, 3D Spatial extent Watershed-Scale, Reach-Scale, Patch-Scale, Grain-Scale, Point-Based Model domain Terrestrial, Hydrology One-line model description Estimate incremental volume changes (erosion and deposition) along the path of a debris flow. Extended model description 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.

Yes If above answer is no, provide end year model development Code development status Active When did you indicate the 'code development status'? 2024 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://github.com/laurenguido/IncrementalDerisFlowVolumeAnalyzer Source csdms web address Program license type BSD or MIT X11 Program license type other Memory requirements Typical run time AOI/batch dependent Describe input parameters - las_file or raster_path: file paths for change detection data, depending on the desired change detection (Las2Ras can be used to convert las_file for use as raster_path) - cell_size: raster resolution for Las2Ras (m) -method: method of interpolation for Las2Ras - grid and dem: file path for pre-event DEM - debris_flow_path: file path for debris flow path shapefile (polyline) - spacing: reach spacing/resolution of query points and investigation polygons (meters) - buffer_width: width of buffer within which volumes will be estimated (meters) - LoD: limit of detection of change detection data (meters) -polygon_ids: IDs of polygons with tributaries for plotting Input format ASCII Other input format Describe output parameters - output_raster: rasterized change detection data from .las - acc_d8: flow accumulation raster - fdir_d8: flow direction raster - output_shapefile_path: query point shapefile - output_shapefile: buffered flow path shapefile - investigation_polygons_shapefile: investigation polygon shapefile (first generated, then populated with volume and geomorphometric data under the same name) Output format ASCII Other output format Pre-processing software needed? Yes Describe pre-processing software 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. Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model 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. Describe key physical parameters and equations Standard flow routing and uniform sampling principles are used to govern the processes of this model. Describe length scale and resolution constraints 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. Describe time scale and resolution constraints 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). Describe any numerical limitations and issues Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? 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. Is there a manual available? No Upload manual if available: Model website if any https://github.com/laurenguido/IncrementalDerisFlowVolumeAnalyzer Model forum / discussion board Comments Please reach out to Lauren Guido (laurenmiller@mines.edu) with any questions. A second version of the script(s) prepared for batch processing has been developed and may be made available upon request. This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component No but possible PyMT component No but possible Is this a data component No Can be coupled with:
