Engineering is the discipline, art, and profession that applies scientific theory to design, develop, and analyze technological solutions. In the contemporary era, it is generally considered to consist of the major basic branches of chemical engineering, civil engineering, electrical engineering, and mechanical engineering.[1] There are numerous other engineering subdisciplines and interdisciplinary subjects that are derived from concentrations, combinations, or extensions of the major engineering branches.

Chemical Engineering

Chemical Engineering is the application of chemical, physical, and biological sciences to the process of converting raw materials or chemicals into more useful or valuable forms.

These include natural and man-made materials, interaction of materials with machines, safety and health, energy conservation, and waste and pollution control. Additionally, students are given experience in plant design and layout, machine and wet process design and improvement, and designing and creating textile products. Throughout the textile engineering curriculum, students take classes from other engineering and disciplines including: mechanical, chemical, materials and industrial engineering.

Generally related to Metallurgy, Corrosion Engineering also relates to non-metallics including ceramics. Corrosion Engineers often manage other not-strictly-corrosion processes including (but not restricted to) cracking, brittle fracture, crazing, fretting, erosion and more..

Civil engineering

Civil engineering comprises the design, construction, and maintenance of the physical and natural built environments.

Subdiscipline Scope Major specialties
Environmental engineering The application of engineering to the improvement and protection of the environment
  • Ecological engineering, the design, monitoring and construction of ecosystems
  • Fire protection engineering, the application of engineering to protect people and environments from fire and smoke
  • Sanitary engineering, the application of engineering methods to improve sanitation of human communities
  • Wastewater engineering Wastewater engineering is a type of engineering that comes from civil engineering and environmental engineering. A wastewater engineer determines the best way to transport or collect rainwater for human populations. Wastewater engineering also deals with the transportation and cleaning of blackwater, greywater, and irrigation water. Wastewater treatment and water reclamation are areas of concern in this field. Wastewater engineers map out topographical and geographical features of Earth to determine the best means of collection. They use sonar scanning in wells to determine volumes of water that can be used for human consumption. Using these types of data they are able to provide a means of collecting water. After collecting the water, it is their job to transport it to where it can be made available for use.
  • Municipal or urban engineering, civil engineering applied to municipal issues such as water and waste management, transportation networks, subdivisions, communications, hydrology, hydraulics, etc.
Geotechnical engineering Concerned with the behavior of geological materials at the site of a civil engineering project
Structural engineering The engineering of structures that support or resist structural loads
Mining engineering Is an engineering discipline that involves the practice, the theory, the science, the technology, and application of extracting and processing minerals from a naturally occurring environment. However, mining engineering is associated with many other sister department within like geology, mineral processing and metallurgy, geotechnical engineering, surveying. A mining engineer manages all phases of mining operations – from exploration and discovery of the mineral resource, through feasibility study, mine design, development of plans, production and operations to mine closure.

With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both during and after mining as a result of the change in the mining area.

Transport engineering The use of engineering to ensure safe and efficient transportation of people and goods
  • Traffic engineering, a branch of transportation engineering focusing on the infrastructure necessary for transportation

  • River engineering is the process of planned human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier.
  • Coastal engineering, the study of the processes ongoing at the shoreline and construction within the coastal zone, often directed at combating erosion of coasts or providing navigational access.
  • Groundwater engineering involves the analysis, monitoring and often modelling of groundwater source to better understand how much remains and if the water can be used for e.g. recharging reservoirs and irrigation.

Energy engineers audit the use of energy in those processes and suggest ways to improve the systems. This means suggesting advanced lighting, better insulation, more efficient heating and cooling properties of buildings.[1] Although an energy engineer is concerned about obtaining and using energy in the most environmentally friendly ways, their field is not limited to strictly renewable energy like hydro, solar, biomass, or geothermal. Energy engineers are also employed by the fields of oil and natural gas extraction

Systems engineering deals with work-processes, optimization methods, and risk management tools. It overlaps technical and human-centered disciplines such as control engineering, industrial engineering, organizational studies, and project management. Systems engineering ensures that all likely aspects of a project or system are considered, and integrated into a whole.
