Summary Also known as Model type Tool Model part of larger framework Note on status model Date note status model Technical specs Supported platforms Unix, Linux, Mac OS, Windows Other platform Programming language Matlab Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2006 Does model development still take place? No If above answer is no, provide end year model development 2009 Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through CSDMS repository Source web address Source csdms web address Program license type Other Program license type other Memory requirements low, depending on dataset Typical run time short, depending on the dataset In/Output Describe input parameters Two input files, all in ESRI ASCII format: DEM Flow direction grid (D8) To change the input files, edit lines 19 for DEM and line 20 for Flow-direction in the source code. Input format ASCII Other input format Describe output parameters Produce 5 output files (ESRI ASCII format): HI.txt - pixel scale hypsometric integral; max_elev.txt - the maximum elevation of the catchment flowing thorough each pixel; Elev_Acc.txt - the sum of the elevation (m) of all the pixels flowing thorough each pixel; flowacc.txt - Contributing area in pixels; To change the names of the output files, edit the last section of the source code. junctions.txt - how many of a pixel's 8 neighbors flow into it; Output format ASCII Other output format Pre-processing software needed? Yes Describe pre-processing software ArcGIS to produce the flow direction file and convert the files to ESRI ASCII format. Post-processing software needed? Yes Describe post-processing software ArcGIS or other GIS package to convert the ASCII files to maps. Visualization software needed? Yes If above answer is yes ESRI, Matlab Other visualization software Process Describe processes represented by the model Describe key physical parameters and equations Calculate the hypsometric integral by HI = (Zbar-Zo)/(Zmax-Zo) where Zbar is the average elevation of the contributing area to a pixel Zo is the local elevation (the elevation of a pixel) Zmax is the maximum elevation of a pixel contributing area.

Hancock (2008), A methodology for calculating the spatial distribution of the area-slope equation and the hypsometric integral within a catchment, Journal of Geophysical Research, 113, F03027. Describe length scale and resolution constraints Describe time scale and resolution constraints Describe any numerical limitations and issues Testing Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets A small DEM and Flow-direction ASCII files Upload test data sets if available: Media:DEM demo.txt, Media:FlowDir demo.txt Describe ideal data for testing Other Do you have current or future plans for collaborating with other researchers? Is there a manual available? No Upload manual if available: Model website if any Model forum / discussion board Comments [[Additional comments model::Running instructions: Copy your input files to the source file directory (or the other way around); Launch MATLAB ; In MATLAB- map the the model directory; Edit the input file name in the source-code file (lines 19 & 20); [Optional] edit the output file names (at the last part of the source-code); Run the script via MATLAB; The output files will be created in the same directory; Use MATLAB to visualize the output or import them to ArcGIS or other GIS package; Good luck]] Download statistics <pbars ytitle=Downloads Title='Monthly Downloads pshic' xlabels=true size=900x200 ymax=10 grid=true box=true cubic=true plots=open xformat=number connected=true angle=90 legend> ,Total downloads: 29 2008 - Jan,0 Feb,0 Mar,0 Apr,0 May,0 Jun,0 Jul,0 Aug,0 Sep,0 Oct,0 Nov,0 Dec,0 2009 - Jan,0 Feb,0 Mar,0 Apr,0 May,0 Jun,0 Jul,0 Aug,0 Sep,0 Oct,0 Nov,0 Dec,0 2010 - Jan,0 Feb,0 Mar,0 Apr,0 May,0 Jun,0 Jul,0 Aug,0 Sep,0 Oct,2 Nov,2 Dec,3 2011 - Jan,4 Feb,0 Mar,2 Apr,0 May,1 Jun,0 Jul,0 Aug,0 Sep,0 Oct,0 Nov,0 Dec,1 2012 - Jan,0 Feb,0 Mar,0 Apr,0 May,1 Jun,0 Jul,0 Aug,0 Sep,0 Oct,0 Nov,0 Dec,0 2013 - Jan,2 Feb,0 Mar,1 Apr,0 May,0 Jun,0 Jul,0 Aug,0 Sep,1 Oct,0 Nov,0 Dec,0 2014 - Jan,0 Feb,0 Mar,2 Apr,0 May,2 Jun,0 Jul,1 Aug,1 Sep,0 Oct,0 Nov,0 Dec,1 2015 - Jan,1 Feb,1 Mar,0 Apr,0 May,0 Jun,0 Jul,0 </pbars> Introduction History Papers Cohen, S., G.
