Hydrologist vs. nature ... PART 1

Hydrologist and nature…

The first tries to understand the other. The other neglects or makes use of the other.
Once instruments are installed in the field (fresh new material) it doesn’t take long until nature takes over. Rain gauges are a popular penthouse for Earwigs or Spiders. Once moved in they play with the tipping bucket, hopping up and down. Excrement is sealing the funnel opening and spoiling data.
