error during watershed delineation

[Pipas Kumar]

dear swat user,

i am facing following problems in watershed delineation. prob 1 & 2 pic attached

prob 1- cell size and cell area are not correct , what i think so.... cell size should be 90 m..as i am viewing in tutorial present in swat site & u tube. how to solve this.


prob 2- why area is showing (0-0)....and value...2.25958.....47E-06.......it is the possible error in DEM... i tried to rectify it but not succeed. i have also projected the DEM to UTM

pls help

regds,

Hi pipas, i think the problem comes from DEM data. Pixel resolution is very small, check again projection of your data, using  gis software (qgis) try to overlay your data with other spatial data like admin bouderies., etc
