Classification of time series easily

Hi all,

I need some help, but don't know, who could help me. So the situation is that I need to classify cca 200 hydrological time series by their chart, and I have no idea how to begin it. I tried to google it, but a lot of difficult methods are on the net and I'm not a math genie and don't understand anyone. I really don't know, how could I solve it easily. Is K-means useable, when timeseries shows autocorrelation? And how?


Thanks in advance
