delineate a basin

Postby huyen.le@tu-bs.de » Mon Aug 09, 2010 13:06

hi,

i want to delineate a basin (drainage network...). The result which i got was only many squares with multiplication signs ( x signs).

I did the steps as following: first I created a grid. I have xyz data and from these data I created a Digital Terrain, and then I removed Depression. The resut from Remove Depression I used to delineate the river network.

In these results, The drainage area looks correct but the river network ist only squares with multiplication signs.

I really dont know why. Maybe you can help me

Thank you in advance

Huyen
