Results

Seasonal Variation
- point by point at different point in water shed
3 sinewaves - precipitation, groundwater (of different points in watershed), what lags show and disagree.
- recharge rate or travel time?
- does temperature respond the same way?
-differences in altitude 
hysteresis between these points. 
temperature
conductivity
