City of 1000 lakes vs City of 8000 springs Sister China

City

:

Wuhan,

Like Wuhan, Christchurch has a high water table, resulting in many springs and waterways.

Wuhan has many freshwater lakes.

Christchurch has the sea coast.

Waterways the springs, rivers, streams, wetlands, estuary and coast - form a natural landscape matrix and structure for this city.

Sister City : Wuhan, China

Reveal our wetlands for amenity, biodiversity & research as at Wuhan

Avon River The natural & heritage feature survives, but can the contributing springs be unearthed?
