This thesis is concerned with springs that appeared in the Hillsborough, Christchurch during the 2010-2011 Canterbury Earthquake Sequence, and which have continued to discharge groundwater to the surface to the present time. Investigations have evolved, measurements of discharge at selected sites, limited chemical data on anions and isotope analysis. The springs are associated with earthquake generated fissures (extensional) and compression zones, mostly in loess-colluvium soils of the valley floor and lower slopes. Extensive peat swamps are present in the Hillsborough valley, with a groundwater table at ~1m below ground. The first appearance of the ‘new’ springs took place following the Mw 7.1 Darfield Earthquake on 4 September 2010, and discharges increased both in volume and extent of the Christchurch Mw 6.3 Earthquake of 22 February 2011. Five monitored sites show flow rates in the range of 4.2-14.4L/min, which have remained effectively constant for the duration of the study (2014-2015). Water chemistry analysis shows that the groundwater discharges are sourced primarily from volcanic bedrocks which underlies the valley at depths ≤50m below ground level. Isotope values confirm similarities with bedrock-sourced groundwater, and the short term (hours-days) influence of extreme rainfall events. Cyclone Lusi (2013-2014) affects were monitored and showed recovery of the bedrock derived water signature within 72 hours. Close to the mouth of the valley sediments interfinger with Waimakiriri River derived alluvium bearing a distinct and different isotope signature. Some mixing is evident at certain locations, but it is not clear if there is any influence from the Huntsbury reservoir which failed in the Port Hills Earthquake (22 February 2011) and stored groundwater from the Christchurch artesian aquifer system (Riccarton Gravel).

A digital copy of a plan for the Greening the Rubble Green Room garden on Colombo Street. The plan shows a sketch of the garden including a raised floor, flower beds, a paved path, and a picket fence. It also contains measurements and notes on what will be planted in the beds.

A photograph of the paved path in the Green Room garden on Colombo Street. The path was designed to travel around the garden, leading up to the platform holding Crack'd for Christchurch's armchair and ottoman artworks.Crack'd for Christchurch comments, "The Green Room was built by Jonathan Hall and planted by Gina Payne."

A photograph of the crowd at the launch of the Green Room on Colombo Street.Crack'd for Christchurch comments, "Before the speeches. The Green Room is on Colombo Street in the centre of the rebuild, with vacant lots surrounding it. We wanted it to be an oasis of calm and hope for Christchurch people. It is only a temporary site."

It is well established that urban green areas provide a wide range of social, aesthetic, environmental and economic benefits. The importance of urban green spaces has been known for decades; however the relationship between urban livability and green areas, as incorporated in overall urban green structure, has become the focus of international studies during the last 10 to 15 years. The spatial structure of green space systems has important consequences for urban form; configuring urban resources, controlling urban size, improving ecological quality of urban areas and preventing or mitigating natural disasters. However, in the field of architecture or urban design, very little work has been done to investigate the potential for built form to define and differentiate the edge to a green corridor ... This thesis therefore poses the hypothesis that architecture and urban design critically mediate between city and green corridor, through intensification and definition of the built edge, as a means of contributing to an ecological city form.

A photograph of the location of the Green Room garden on Colombo Street. White picket fences have been placed around the edges of the site and a platform has been partially constructed in the back-right corner. Wire fences have been placed around the entire section as a cordon.Crack'd for Christchurch comments, "The Green Room was built by Jonathan Hall and planted by Gina Payne."
