Project Overview
Sihwa Lake is an estuarine ecosystem connected to the Yellow Sea, featuring tidal mudflats, a tidal power plant, and urban basins with five inflow streams. | Enhanced/Maintained: Habitats for species (mudflats & wetlands support endangered birds). Waste-water treatment (reed wetlands purify water). Recreation & mental health (waterfront parks & citizen programs).
Ecosystem Services
Provisioning
- Provisioning Services are ecosystem services that describe the material or energy outputs from ecosystems. They include food, water and other resources.
Regulating
- Regulating Services are the services that ecosystems provide by acting as regulators eg. regulating the quality of air and soil or by providing flood and disease control.
- Local climate and air quality: Trees provide shade whilst forests influence rainfall and water availability both locally and regionally. Trees or other plants also play an important role in regulating air quality by removing pollutants from the atmosphere.
- Waste-water treatment: Ecosystems such as wetlands filter both human and animal waste and act as a natural buffer to the surrounding environment. Through the biological activity of microorganisms in the soil, most waste is broken down. Thereby pathogens (disease causing microbes) are eliminated, and the level of nutrients and pollution is reduced.
Habitat / Supporting
- Ecosystem services "that are necessary for the production of all other ecosystem services". These include services such as nutrient recycling, primary production and soil formation.
- Habitats for species: Habitats provide everything that an individual plant or animal needs to survive: food; water; and shelter. Each ecosystem provides different habitats that can be essential for a species’ lifecycle. Migratory species including birds, fish, mammals and insects all depend upon different ecosystems during their movements.
Cultural
- Cultural Services corresponds nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences.
- Recreation and mental and physical health: Walking and playing sports in green space is not only a good form of physical exercise but also lets people relax. The role that green space plays in maintaining mental and physical health is increasingly being recognized, despite difficulties of measurement.

EH Engineering Solutions
Artificial Reed Wetland Creating artificial wetlands with
Artificial Reed Wetland Creating artificial wetlands with aquatic plants like reeds facilitates natural water purification. These wetlands establish an ecological circulation system where water, soil, microorganisms, plants, and animals interact organically, achieving a balance and self-sustaining ecosystem.

In the Sihwa district, local governments and related organisations are working to create infrastructure
Sihwa Lake receives inflow from nine sources,
Sihwa Lake receives inflow from nine sources, which are four main water ways and five streams; Singil cheon, Ansan-cheon, Banwol-cheon, Donghwa-cheon, and Donghwa-cheon. Among them, streams have been evaluated and detailed in terms of instream flow and flow rate under normal, drought and flood conditions.
