A Day In The Life

Hydrologists study how water moves through the earth’s crust and develops in the earth’s atmosphere.  They study how rain, snow and other forms of precipitation impact fiver flows and ground water levels and how that water then evaporates back into the atmosphere.

They will use remote sensing equipment and tools to do research and collect data.  Complex computer models are made with highly sophisticated computer programs to analyze the data they collect.  They also use geographic information systems (GIS) and global positioning systems (GPS) equipment and tools to assist them with their research.

Most individuals specialize in certain aspects or specific water sources and water cycles like precipitation, evaporation, droughts and flooding.  For example:

Groundwater Hydrologist-studies the water below the earth’s surface.  They generally focus on the clean-up of contaminated groundwater.  While others focus on finding and maintaining water supply and finds the best locations of wells.

Surface Water Hydrologist-studies water above ground like streams, lakes and ponds.  They try to collect precipitation data to attempt to predict future water levels and potential drought levels.  They also produce future flood forecasts and develop water management plans.

Typical Work Schedule

This is a full-time position.  Often spent in an office or laboratory, but also spent on location studying different sites.

Projected Job Growth
