Nationalstadsparken delta reserve

Abstract: Stockholm is built on top of a rare landscape phenomenon: At the ridge of an esker crossing where the sweet water of Mälaren meets the brakish of the Baltic sea. An absolute ecological melting pot, not to be found anywhere else in this part of the world.  Due to the development of Stockholm, the nature of what takes place here has over the past 800 years slowly been lost in the citys urban web. As the citys development continues and generates a land-mass-bi-product in shape of blast stone. -Could the ecology of this rare aquatic environment connecting sweet and brakish be regenerated if the connection was recreated artificially with excess blast stone?
