ENVIRONMENTAL ENGINEERINGEnvironmental engineering is about identifying environmental problems and
creatively developing effective solutions to them.
Different fields |
Sustainable engineering
Sustainable engineering takes environmental engineering concepts to the next
level by looking at the interactions between technical, ecological, social and
economic systems and by avoiding shifting problems from one area to the other.
Sustainability means living well within the ecological limits of a finite planet.
More than ever, engineers need to find holistic and effective solutions to
protect our vital life support systems and, at the same time, meet the needs of
a growing human population.
Concepts such as life cycle thinking, industrial ecology and sustainable systems
engineering are important elements in the education and work practice of a
sustainable engineer.
As an environmental engineer specialized in sustainability, you
a) gain a profound understanding of the holistic principles of industrial
ecology, resource efficiency, eco-design, risk management and sustainable
consumption and production
b) understand environmental and sustainability frameworks on corporate and
regional sustainable development
c) have expert knowledge in sustainability assessment methods and tools, such as
life cycle assessment, material flow analysis, environmental footprint and
input-output analysis
d) work on solutions for problems that matter: climate change, water
availability, energy futures, waste management and low-carbon living, etc.
Transport engineering
Transport engineers plan, design and operate the large public and private
infrastructure systems that connect our physical world.
We need a broad range of continually evolving, large-scale transport
infrastructure, including road, rail, air and water. Transport engineers
quantify and optimize our mobility infrastructure networks to meet travel and
freight demands, while ensuring safety, equity and sustainability, at minimal
levels of congestion and cost.
Transport engineering has always been one of the essential civil engineering
disciplines, impacting roadways, bridges, transit stations, airports and sea
ports etc. Transport engineering has now developed into a multidisciplinary
field spanning economics, politics, sociology and psychology, in addition to its
core mathematical, engineering and computational principles.
Transport planning
Transport planning involves developing mathematical techniques for:
a) forecasting travel demand and planning to accommodate growth in demand
b) determining improvements to the transport infrastructure
c) reducing emissions
d) reducing energy use.
Computational transport planning uses mathematical methods to predict, represent
and quantify:
a) the evolution of land use in cities
b) travel attributes such as trip purpose
c) travel decisions, including mode choice.
Planning models then examine the feasibility of projects and policies through
cost-benefit and scenario analysis.
Transport design
Transport engineers face multi-faceted design decisions when they are designing
optimized transport infrastructure networks. These might relate to:
a) the physical expansion of transport facilities, such as lane width or the
number of lanes, for a roadway
b) the materials and thickness used in pavements
c) the geometry of a facility, such as a roadway, rail line or airport
d) road pricing schemes
e) deploying information-based technology.
In all design decisions, multiple performance measures, cost metrics and safety
criteria must be considered and weighed.
Transport operations
Transport operations, whether for road, rail, port or air traffic, are designed
to minimize travel delays, improve safety, reduce emissions and enhance
reliability, as well as taking other considerations into account.
Transport operation decisions involve:
a) optimizing traffic signals
b) setting specific tolls
c) designing traffic signs and markings.
With the development of new Intelligent Transportation Systems (ITS), transport
engineers use tools including advanced traveler information systems (such as
variable message signs), advanced traffic control systems (such as ramp meters)
and vehicle-to-vehicle (V2V) communications to optimize the performance of the
transport system.
Water engineering
Water engineering is about how water interacts with all aspects of the built and
natural environments.
Water engineering looks at the way that natural systems such as rivers,
estuaries and the coasts behave, as well as designing infrastructure to store
and direct water.
Water engineering is concerned with:
a) water needs in different parts of Africa – this includes drinking water,
water for industry and agriculture and, importantly, water for the natural
environment.
b) flooding – one of the most costly natural disasters for Africa and around the
world.
c) groundwater – water that lies in underground aquifers and deep in the soil.
d) coastal water behavior – what happens when rivers meet the sea, and when the
sea meets the land.
e) water quality requirements.
As a company we are finding innovative methods and sustainable solutions to the
threats that are facing the environment. The Environmental program has its
roots in the natural, technological and social sciences. We will gain insight
into the socio-economic causes and the characteristics of pollution and
degradation of the natural environment, including the effects on human beings,
the atmosphere, ecosystems and other organisms. This program is based on an
interdisciplinary approach. We teach local people to develop analytical tools
and models, as well as technologies, socio-political arrangements and economic
instruments to prevent and control environmental and sustainability issues.
