Thanks for prompt replies, But the problem i am facing is i have basically 4 attributes which i am taking into consideration for flood prediction in my area of study.
I have rainfall data from jan - dec from 1901-2001
I have an DEM image from which i will figure out slope, flow direction and flow accumulation using ARC-Hydro.
Now i want to put these data each one as a separate input layer to network so that it can predict the outcome of flood.
