Integrated assessment of storm surge barrier systems under present and future climates and comparison to alternatives: a case study of Boston, USA

Large-scale barriers are a management option for present and increasing coastal storm flooding. The barriers have gates that are open most times except during storms. As an example of the assessment process for a barrier, an integrated assessment of two barrier options for the coastal city of Boston, located in the northeastern USA, is presented. The assessment also included a comparison to shore-based adaptation options such as elevated walkways, playing fields, and open space.
