I am trying to use qgis to delineate between three sub-sub-catchments.

I have contour shape file of 20 meter height.

Sub-catchment is about 12 square kilometers area but consist of three sub-sub-catchments. Would like to use the information to determine the river density of each sb--sub-catchment.

Also would like to do slope calculation, using (exported to excel for graph profile).

regards

Zayed

Welcome to GIS.SE! Have you tried anything yet, have you hit any particular problems? Or are you just looking for a general 'Point me in the right direction'. Questions like this that initially look like 'do the work for me' questions have a habit of getting ignored, so try and phrase your question in such a way as to give people something solid to answer, and as always, check the FAQ –  Rob Quincey May 8 '13 at 11:52
