Thank you for the repply Stacie. I aprecciate the help !
I tried re-processing the drainage layer but unfortunately the model got the error again.
I would like to make another question about what is writen in the guide of SDR. I don´t know if I can ask here.
Its written: “IC is a function of both the area upslope of each pixel (Dup) and the flow path between the pixel and the nearest stream (Ddn). If the upslope area is large, has lower slope, and good vegetative cover (so a low USLE C factor), Dup will be low, indicating a lower potential for sediment to make it to the stream. Similarly, if the downslope path between the pixel and the stream is long, has lower slope and good vegetative cover, Ddn will be low.”
I didn’t understand why Ddn would be low. Wouldn’t it be high?
Thansks for the attention.
