The Swan Shoal is a nature-based coastal protection system that has been developed as a sustainable alternative to protect Copenhagen from the impacts of climate change, specifically storm surges and rising sea levels. The system uses natural elements and processes to provide protection, which helps to avoid negative environmental impacts and preserve the marine environment and nature. By doing so, the Swan Shoal serves as an example of a nature-based solution that addresses both the needs of human society and the conservation of natural resources.

Maintaining the balance and sustainability of the marine environment in Øresund is crucial for preserving essential oceanic streams, including "Kongedybet" and "Hollænderdybet." These streams operate in a cyclical and collaborative manner, and their preservation is essential for ensuring the viability of marine life. In this regard, the Swan Shoal plays a significant role in the preservation of these essential streams, such as Kongedybet.
