Input data used in the preparation of the … Input data used in the preparation of the associated manuscript is all available from www.opentopography.org along with all processing and visualization code at https://github.com/sgrieve/LH_Paper_Plotting so users can compare their results with those contained within the manuscript.ith those contained within the manuscript. +
Any 1m resolution digital elevation model. +
The input files are a DEM in .flt format, … The input files are a DEM in .flt format, a channel heads file generated using the DrEICH algorithm (https://csdms.colorado.edu/wiki/Model:DrEICH_algorithm) and an optional floodplain mask in .flt format. Input parameters are also supplied at the command line. Information on the parameters is available in the documentation (http://www.geos.ed.ac.uk/~smudd/LSDTT_docs/html/channel_heads.html).smudd/LSDTT_docs/html/channel_heads.html). +
This algorithm attempts to measure individual hillslopes, which are can be resolved at a range of spatial scales. It is recommended to use high resolution topographic data (<4 meter resolution) to ensure that a broad range of hillslopes can be sampled. +
As the size of the DEM increases, processing time will increase. An 8000*8000 DEM will take several days to process. Documentation is available to help users select appropriate input parameters. +
The output data is both plain text data files and .flt raster files containing the spatial location of the computed results. +
A channel network must be extracted for the landscape, this is performed using the DrEICH algorithm (https://csdms.colorado.edu/wiki/Model:DrEICH_algorithm). +
The module generates hillslope profiles by routing flow from every point on a drainage divide into a channel. +
No time resolution constraints as this software performs topographic analysis. +

This tool produces a flow path for each hi … This tool produces a flow path for each hilltop pixel on a landscape, generating hillslope length and relief data at a hillslope scale. These data can be used to discriminate between linear and nonlinear sediment flux laws at a landscape scale.</br></br>The model requires an input DEM in float format and produces a series raster and plain text output files which can be visualized and analysed using code provided at: https://github.com/sgrieve/LH_Paper_Plotting</br></br>For detailed information about how to use this tool please refer to the documentation (http://www.geos.ed.ac.uk/~smudd/LSDTT_docs/html/basin_metrics.html).smudd/LSDTT_docs/html/basin_metrics.html). +
