Hydrologists: Salary Overview

Hydrologists study the movement of water across and through the Earth’s crust.

They typically analyze the impact of rain, snow, and other precipitations on river flows and groundwater levels and how water evaporates back into the atmosphere and eventually reaches the ocean.

A hydrologist’s job description usually includes measuring the volume of water, collecting water and soil samples to test for pH and other properties, analyzing data, trying to find ways of minimizing the negative impact of pollution on the environment, forecasting future water supplies using computer models, evaluating and deciding if water-related projects are feasible, and writing reports.

Many hydrologists specialize in a particular water source; for example, some specialize in groundwater hydrology while others specialize in surface water hydrology.

As a hydrologist, you may have to travel often and you may have to wade into lakes and streams to collect water samples or to inspect monitoring equipment.
