A photograph of the partially-completed Green Room garden on Colombo Street. Crack'd for Christchurch's armchair and mosaic artworks are on a platform in the back. The armchair and ottoman have been wrapped in tarpaulins until their unveiling. Wire fences have been placed around the section as a cordon.Crack'd for Christchurch comments, "Flora and Otto waiting for their big day, with the garden still to be finished."

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 constructed in the back-right corner. Two garden plots have been sectioned off using bricks to the right and front of the site. The front plot has been planted with shrubs and grass. A path leading between the gardens up to the platform has been filled with gravel. 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."

The title reads 'Greener square for Christchurch?..' The cartoon depicts the city centre in Christchurch entirely covered with green and there are cows wandering by the stream as well as grazing on the tops of buildings. A man at the top of the green cathedral says 'I can see it really growing on me!' Context: This is a reference to the draft Central City plan under which the Central City will be greener and more attractive. Quantity: 1 digital cartoon(s).

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 photograph captioned, "I was reading in the paper this morning about one of the people who was orange and then went red yesterday. They said they were really glad they'd gone red rather than green-blue. Green-blue is the one they're going to have problems with".
