The leading example of a restored urban waterway is the Cheonggyecheon in Seoul, a multi-million dollar linear park that has inspired other cities worldwide to follow this example. Among other Korean cities, the southern city of Busan has its own examples of urban streams restored and others that are covered by streets and buildings.
Like New York, Busan is a true metropolis covering smaller former municipalities that it absorbed over the decades. The stream flowing through the city center is the Dongcheon, which runs partially underground with the rest flowing neglected beneath highways. But there are a small signs of a stream revival underway hinting at a greener future.
