Describe processes represented by the model [[Describe processes::The module can be split into three processes. First computing topographic curvature (laplacian), slope and aspect from a gridded DEM over variable length scales to reduce local scale noise below the scale of interest (e.g. vegetation, boulders/rubble) (see Hurst et al. [2012] for further justification). Secondly, extraction of a network of hilltops as the intersecting margins of adjoining drainage basins at all stream orders through hydrological analysis of the DEM. Third, the use of the hilltop network to extract the spatial distribution of hillslope properties (hilltop curvature, mean hillslope gradient and hillslope length) by aspect driven steepest-descent tracing.]]
Describe key physical parameters and equations
Describe length scale and resolution constraints Requires high resolution (1 m LiDAR) topographic data.
Describe time scale and resolution constraints
Describe any numerical limitations and issues Dpeending on the size of the DEM this can be quite a slow process, particularly the third step.


Describe available calibration data sets
Upload calibration data sets if available:
Describe available test data sets Db_dem.zip
Upload test data sets if available:
Describe ideal data for testing


Do you have current or future plans for collaborating with other researchers? This code has been subsumed into a topographic analysis package being developed with Simon Mudd at the University of Edinburgh which may be available at a future date.
Is there a manual available? No
Upload manual if available:
