Hydrology is the study of water on Earth. This discipline of the Earth Sciences focuses on the hydrologic cycle, watersheds, stream flow, flooding, and groundwater. Students of hydrology investigate the impacts of population growth, urbanization, weather, and climate upon these dynamic hydrologic processes and upon water resource sustainability.

The COD Earth Sciences Program is cutting edge in providing a fundamental hydrology course that meets the general education needs for non-science and science majors. Students enrolled in the Hydrosciences courses (Hydrology and Oceanography), have the opportunity to work in a lab equipped with stream tables, bench-scale aquifer models, and a functioning beach wave tank – facilities unmatched in community colleges.

“The prosperity of the greater Chicago region and its status as a global center depend on water availability. Historically blessed with ample fresh water, the region can no longer assume that water supplies are infinite. While other parts of the country struggle to meet growing water demand and some cities are losing their economic competitiveness due to shortage or inadequate planning, the Chicago region must act now to carefully plan and manage its surface and groundwater resources in a coordinated fashion. Nothing less than economic development, environmental protection, and social equity are at stake. And it is for these reasons that the region’s first water supply plan is timely and important.”

Earth 1135 Water Science - Fundamentals of Hydrology

Metropolitan Water Reclamation District of Greater Chicago

Field trip to Mainstream Pumping Station, MWRDGC Deep Tunnel, Spring 2011

Sign up for Earth Science 1135 to fulfill your General Education Physical Science lab course requirement. This course is relevant if you use water or would defend our water resources.

An introduction to the water cycle, the dynamic processes of surface water, and ground water. Students investigate and analyze the impacts of population growth, urbanization, weather, and climate upon hydrological processes and water resource sustainability. One field trip is required. For any student concerned about water resources and those with intended majors in geology, hydrology, meteorology, environmental sciences/engineering, or resource management.

Salt Creek Gaging Station

Field trip to USGS Salt Creek Gaging Station: Students deploy the ACDP to measure depth of Salt Creek channel.

    “My advice to students is to take your classes seriously. Just taking college classes is not enough to get you a valuable degree. You have to actually learn the material to be able to use it in real situations. Otherwise, your college degree is just a really expensive piece of paper. Find something you enjoy, or at least something you don’t hate, and work hard to become the best at it. If you’re working toward anything less, chances are you’re in the wrong field.”
