between meeting needs and protecting resources. It is thus linked to environmental protection, sustainability, and integrated landscape management.
Environmental risk management The conscious and coordinated effort in
appraising the potential and/or existing impact of various productive activities
on their environment and people.
Environmental science It is an interdisciplinary academic field that integrates
physical, biological, and information sciences (including ecology, biology, chemistry, mathematics, microbiology, geology, information science, etc.)
Environmental studies It is a multidisciplinary academic field, which systematically studies human interaction with the environment in the interests solving
complex problems. Environmental studies brings together the principles of the
physical sciences, commerce/economics, and social sciences so as to solve
contemporary environmental problems. It is a broad field of study that includes
the natural environment, the built environment, and the sets of relationships
between them. The field encompasses study in basic principles of ecology and
environmental science, as well as associated subjects such as ethics, geography,
anthropology, policy, politics, urban-planning, law, economics, philosophy, sociology and social justice, planning, pollution control, and natural resource management. There are also many degree programs in Environmental Studies
including a Master’s degree and a Bachelor’s degree.
Environmental technology It may include (envirotech), green technology
(greentech), or clean technology (cleantech). It is the application of one or more
of environmental science, green chemistry, environmental monitoring, and electronic devices to monitor, model, and conserve the natural environment and
resources, and to curb the negative impacts of human involvement. The term is
also used to describe sustainable energy generation technologies such as photovoltaics, wind turbines, bioreactors, etc. Sustainable development is the core of
environmental technologies. The term environmental technologies is also used to
describe a class of electronic devices that can promote sustainable management of
resources.
Equalization basin A holding basin in which variations in flow and composition of
a liquid are averaged. Such basins are used to provide a flow of reasonably
uniform volume and composition to a treatment unit. Also called a balancing
reservoir.
Estuary Body of water that is located at the lower end of a river and is subject to
tidal fluctuations.
Eutrophication (a) Nutrient overenrichment of a body of water, causing increased
growth of algae and rooted aquatic plants. (b) Overenrichment of a water body
with nutrients, resulting in excessive growth of organisms and depletion of
oxygen concentration. (c) The increase of nutrient levels of a lake or other body
of water; this usually causes an increase in the growth of aquatic animal and
plant life.
Evacuation The organized, phased, and supervised withdrawal, dispersal, or
removal of children, personnel, and visitors from dangerous or potentially dangerous areas.
