Hydrology Flume

Pictured is a flume used by the Earth and Atmospheric Sciences (EAS) Department. A flume is an elongated tank with water moving through it. A recirculating flume uses a large water pump to recycle water from the outlet back to the inlet. Flumes are used to model the hydraulics of water flow over and around model dams and over sediments such as sand. It also models the movement of sediments over bed features such as sandbars. The EAS recirculating flume is used as a demonstration device for first year classes such as EAS 105, Water Environment, and EAS 109, Geologic Environment. It is also a research tool for the advanced courses EAS 230, Dynamic Water Systems, EAS 338, River Hydraulics, and EAS 434, Surface Water Modeling.

Grand Canyon Field Trip

The Earth and Atmospheric Sciences (EAS) Department conducts field trips to various parts of the United States, usually during the spring break interval. The department has conducted field trips to the Grand Canyon in Arizona about every five years. The last field trip was conducted in the spring of 2002 to the North Rim of the Grand Canyon. This area is the most remote region in the lower 48-states. The class EAS 401, Earth Sciences Field Studies (Topical), allows students to examine various geologic and hydrologic environments and apply field techniques which they have learned in their various classes. In the photograph, Dr. Charles Nelson and his students are sitting on an extinct cinder volcano at Toroweap, known as Vulcan's Throne, which allows spectacular views of the inner gorge of the Grand Canyon.

Doppler Radar Antenna

Pictured is an antenna for the Doppler Radar operated by the Department of Earth and Atmospheric Sciences. The antenna sits on top of the Mathematics and Science Center. The radar is used in basic and advanced meteorology classes to teach radar principles, storm identification, tracking and prediction. It is also used by hydrology students to study rainfall distribution patterns.

Lightning photograph from a field trip

The photograph of lightning was taken at Rattle Snake Hills, Wyoming, on a field geology course in August of 2003. Lightning is simply a discharge of electricity, a giant spark, which occurs in mature thunderstorms. Lightning may take place within a cloud, between clouds, from a cloud to the surrounding air, or from a cloud to the ground.

St. Helena Canyon

Pictured is the St. Helena Canyon located in the Big Bend National Park. The photograph was taken by a student in the class Earth and Atmospheric Sciences (EAS) 401, Earth Sciences Field Studies (Topical). The EAS 401 class conducts annual field trips which include field studies of the geology of various regions.

Tenth Street Dam

Pictured is the Tenth Street Dam on the Mississippi River, located next to the St. Cloud State University Campus. The dam is an example of a hydraulic structure. Various features of the dam include a three foot flip up gate at the top to raise the water level and dragon’s teeth at the bottom which are used to disperse energy. The energy is then converted into electricity by a power plant located next to the dam. The dam is used by various hydrology classes to demonstrate hydrodynamic properties and to show how power is converted into electricity.
