Dear Atilla Thanks .I am trying to find out the Morphological characteuictics like Elongation ratio, to get the drainage density

Well, I think this will be helpfull for you:

Zavoianu, I., 1985: Morphometry of Drainage Basins, Developments in Water Science, 20. Elsevier.

(For elongation ratio, page: 106).

Kind regards...

Thanks
