how to draw hypsometric curve using ArcGis

bismillah aloud together I helped us refine today we are going to see how to draw a head symmetric curve on ArcGIS so what's wrong but we are in need so this is the form of the watershed which I want to use this is the water shadow pencil which has a surface of 99.7 square kilometer so first of all like I need to open ArcGIS then I will open the digital elevation model then of that of that watershed so this is the digital elevation model of that watershed so first table click here and select and select standard deviation and apply then ok then I have to double click here double click here go to unique values yes then I have to go to classified and select here so this is this is the excel file of how to draw EPSA mr. curve you need the fields of altitude the surface the partial surface the altitude here in the reverse reverse form the surface in percentage and the accumulated surface like Yasin here so I am going to fill those currents of maximum elevation minimal invasion and surface as we have or as we said that the surface is 2099 I'm going to fill it here the maximum here the maximum here is the maximum elevation is one thousand five hundred thirty two point forty so one thousand five hundred thirty two point forty and the minimum is he is 488 2,400 point twenty meter and here you are seeing that the meanwhile our titude is one eight hundred fifty six point twenty six so here I have to classify that elevate that's them depending on the elevation classes which I have here from 495 or 488 depending on the class and here to 500 so I have to go here equal interval how many lines one two three four five six seven eight nine 11:12 sever her I need to 12 12 classes so first two I starting to buy 500 then I'm going from here No 100 1,300 1,200 1,100 1,000 900 800 700 600 500 so this is the intervals I'm going to click OK and apply like this so this is the classes this is the dem classified depending on the elevation classes now I have to go to our tool box here check our tool box I have to wage the response of our tool box so go to 3d analyst tools roster club or class under classified so I have to choose the dam and this is the classes which you have or what you are seeing here this is I can select so now I have to do or click OK I have to point the answer so this is the answer depending on the this is the thrust of classified depending the revision classes now I have to go to research and click to raster to polygon like this polygon and search select raster to polygon and select the new file and click OK so this is the the polygon the result of the polygon containing the surfaces of the different innovation classes here I have to go to editor start editing then open attribute table selects but I by attribute and go to select grid get grid code here gets unique value sorry like I see that we have 12 values so I have to click equal to 1 and select apply then I have to go to editor and click merge yes and 2 is the same apply and merge and 3 is the same apply and like this till reaching the last the last value which is 12 so this is the last value of 12 apply and merge okay now I have to go to here and sorts by ascending from 1 to 12 like this then I have to go to editor and stop editing yes close this window and go to here and select export I have to select the file on see the file of pencil a watershed like you are seeing here and select here debase table and click polygon polygon surfaces of pensaba water like this and safe okay and no I have to go to the sea the sea partition van sala watershed file and I have to select polygon surfaces here selects new new window on Excel and try to control translate that's fire polygon surfaces of pencil a quarter shot point DVF have to translate it on the new window of Excel I can see in here so this is the results and the results are not classified depending on the one from from 1 to 3 from 1 to 12 so here I have to classified depending on that order so here I have in general rules I need I need to close or delete those areas leads also this and try to merge try to merge those codes here I have to click 0 top early just temporarily and go to data okay so this is the data from 1 to 12 like a saying I can connect grid code another time like I see so here as you are seeing that the value are in square meter I mean I need them in square kilometer so I have to divide it on 1 million to convert them from square meter to square kilometer I have to divide them in 1 million like I seeing and ok have to translate from here to apply on all the watershed so I need to check that the surfaces or the summing or the total surface of the partial surfaces are 2099 like are seeing so I have to do something here so I like icing at two thousand nine ninety nine point two forty five just small and small difference it's not it's not important so like I'll see so from here I have to copy those go to word passed then copy it another time to the excel file like you are seeing here so here just to fix that error by selecting a one naughty - and here also he want to calculate the serfs in percentage you have to divide that partial surface on the total surface and multiply its in hundred to see and to find it like this so this is the hypsometric curve to trace the hypsometric curve you need you need those cards the accumulated surface and you need also the altitude former altitude to trace to trace the obsolete red curve here we have elevations and y axis and x axis we have the accumulated surfaces in 100 so this is the hypsometric curve I hope that I was clear and I hope for for you also to success to apply that thank you very much and take off yourself and Salam aleikum
