Which of these tasks would a hydrologist be most likely to perform?
GuDViN [60]

Hydrologists are most likely to perform actions relating to estimating the amount of groundwater in an aquifer.

<h3>Hydrologists</h3>

Thus, species identification, age of fossils, or extracting underground oils have nothing to do with the work of hydrologists.
