Dear Friends,
I'm currently reading articles related to watershed hydrology with focus on watershed scale, small scale and large scale. I wonder if you could explain what small scale and large scale is ?
Please kindly state the size and measure of small scales and large scales. Is there any standard number for small scale and large scale watersheds?
your help is much appreciated.
regards,
Hadi
