Hysteresis

Hi.

Basically, as part of a final-year river management module, I need to work out the hysteresis formed by two separate datasets;

1. The discharge measured within a river over a 10-hour period;
2. The suspended sediment concentration within the same river, measured over the same 10 hours.

I have 2 graphs from the data.

The discharge data forms a positively skewed trend, not dissimilar to this:

The suspended sediment concentration data forms a trend with a lesser positive skew, not dissimilar to this:

I need to work out the hysteresis. I am not sure how I should go about working this out - do I need to create a hysteresis loop? If so, how should I go about doing this?

Any sensible advice is much appreciated.

Thanks in advance.
