Agricultural engineers design, manage and develop systems and equipment that produce, process, package and distribute the world's food supplies. They also are involved with the design and management of natural resources and rural environmental systems. They help develop processes that add value to food products.
Civil engineers design and construct facilities that make our modern civilization possible.
A structural engineer may specialize in the analysis and design of anything from bridges, buildings and spacecraft to mountain tunnels, dams and rocket-launching pads. Geotechnical engineers evaluate the engineering properties of soils and use this information to design structural foundations, highway roadbeds, and solutions to groundwater pollution problems. Transportation engineers design the streets, highways, and airports so vital to the growth and prosperity of our nation's economy. Hydraulic and water resource engineers can engage in watershed studies or consider the effects on recreation, wildlife, and pollution. They also deal with the design of dams, spillways, canals, pumping stations and hydroelectric plants.
