Irrigation engineering involves the analysis, design and construction of modern irrigation systems such as canals and dams. Sewage treatment involves eliminating contaminants in sewage water so it is fit for human consumption. Career opportunities in this field are many, including environments that use irrigation such as farms and sanitation plants. Self employment is another option, though it takes time to build your reputation in the field. A qualified hydraulic engineer may earn $53,000 to $70,000 annually as of 2011, according to Salarylist.
This branch of civil engineering deals mainly with the study of behavior of earth materials such as soil and bedrock. A geotechnical engineer analyzes soil at a construction site as part of foundation design. Geotechnical engineering jobs can be found in the mining sector, such as quarries and land reclamation firms. Positions in the field include geotechnical division manager, geotechnical research associate and geotechnical project coordinator. The average salary for a geotechnical engineer is about $57,000 as of 2011, but some organizations offer as much as $200,000 to $300,000 annually, reports Salarylist.
Structural engineering are involved in the design, construction and maintenance of structures such as hospitals, bridges, skyscrapers and sports stadia offer. Job opportunities in this field include employment in construction firms and the government. Self employment is also an option. Structural engineers earn an average salary of about $56,000 as of 2011, says Salarylist.
This branch of civil engineering involves planning for the safe and free movement of people and goods. Jobs in this field are available in local and state traffic agencies where engineers traffic signs and signals. Jobs in private firms are also available where engineers determine amount of load to be transported by trucks. Unlike the other types of engineering jobs, the transport engineering sector does not offer self employment.
