ENGINEERED WETLAND FOR SUSTAINABLE URBAN ENVIRONMENT

Although wetlands are often wet, a wetland might not be wet year round. In fact,
some of the most important wetlands are only seasonally wet. Wetlands are the link
between the land and. the water. They are transition zones where the flow of water, the
cycling of nutrients, and the energy of the sun meet to produce a unique ecosystem
characterized by hydrology, soils and vegetation-making these areas very important
features of a watershed.
Wetlands are among the most productive ecosystems in the world, comparable to
rain forests and coral reefs. An immense variety of species of microbes, plants, insects,
amphibian, reptiles, birds, fish and mammals can be a part of the wetland system.
Physical and chemical features such as climate, landscape shape, geology and the
movement and abundance of water help to determine the plants and animals that inhabit
each wetland.
The objective of this project is to develop studies on the principle of engineered
wetland that can be applied for sustainable urban environment. Wetland is mainly design
for landscaping purpose and the criteria on environment and ecological issues have often
been neglected. To an engineer a wetland may be a place that will require a specialized
construction design to accommodate poorly drained soils. The scientist likely has a
functional perspective, defining a wetland as a place where anaerobic processes occur,
and plants are adapted especially for living in saturated or inundated conditions.
Therefore, the objective of this project is to study the appropriate design of engineered
wetlands that can fulfil the requirements from engineering and also the scientific
perspectives. The solution is to design a wetland to become an ecological wetland
besides of landscaping purpose. The scope of study of this project covers a wide range of
engineering and biological scopes, including water turbidity test, BOD, COD
experiments, site surveying, water flow measuring (weir), study of landscape drawing,
engineering documentation and engineering ethics.
In short, the result of this project will include a design of a wetland for sustainable
urban environment.
