A digitally manipulated photograph of a shop security shutter. The photographer comments, "Sometimes before you feel the ground rolling any metal shutters around start their rattling noises as if someone is shaking them".

The badly twisted Medway Street footbridge. The photographer comments, "The September 4th 2010 earthquake in Christchurch was so violent that the banks of the Avon River moved towards each other. This footbridge being metal had to twist sideways to release the pressure of being pushed from both river banks. It looked like it had been wrung out like a wet towel".

Following the 2010/2011 Canterbury (New Zealand) earthquakes the seismic design of buildings with precast concrete panels has received significant attention. Although this form of construction generally performed adequately in Christchurch, there were a considerable number of precast concrete panel connection failures. This observation prompted a review of more than 4700 panel details to establish representative details used in both existing and new multi-storey and low rise industrial precast concrete buildings. The detailing and quantity of each reviewed connection type in the sampled data is reported, and advantages and potential deficiencies of each connection type are discussed. Following the Canterbury earthquakes, it was observed that brittle failure had occurred in some grouted metal duct connections used for precast concrete wall panels, resulting in recommendations for more robust detailing of this connection type. A set of experimental tests was subsequently performed to investigate the in-plane seismic behaviour of precast concrete wall panel connections. This testing comprised of seven reversed cyclic in-plane tests of fullscale precast concrete wall panels having wall-to-foundation grouted metal duct connections. Walls with existing connection detailing were found to perform adequately when carrying low axial loads, but performance was found to be less satisfactory as the axial load and wall panel length increased. The use of new recommended detailing was observed to prevent brittle connection response and to improve the robustness of the reinforcement splice. A parametric investigation was conducted using the finite element method to predict the failure mode of metal duct connections. From the results of the parametric study on metal duct connections it was identified that there were three possible failure modes, being reinforcement fracture, concrete spalling without metal duct pull out, and concrete spalling with metal duct pull-out. An alternative simple analytical method was proposed in order to determine the type of connection failure without using a time-consuming finite element method. Grouted sleeves inserts are an alternative connector that is widely used to connect wall panels to the foundations. The two full-scale wall panels were subjected to reversed cyclic in-plane demands until failure of either the connection or the wall panel. Wall panel failure was due to a combination of connection reinforcement pulling-out from the coupler and reinforcement fracture. In addition, non-embedded grouted sleeve tests filled with different quality of grout were conducted by subjecting these coupler assemblages to cyclic and monotonic forces

Corrogated roofing from the demolition of the QEII complex. The photographer comments, "This collection of galvanised roofing looks so photogenic as I walked around the partly demolished Queen Elizabeth stadium and swimming pool".

A pigeon perches in the beams of a damaged building. The photographer comments, "The building next door was demolished after the Christchurch earthquake, which exposed the side of this building with it's very old corrugated iron walls. Some of the sheeting was damaged and exposed parts of the interior. The pigeon was sitting on a bit of wood with the beam above it had a very serious crack. I think you would be nervous as well".

The roof of this collapsed building on Atlas Lane has fallen almost intact on top of the rubble. The photographer comments, "Whenever I go past this place it reminds me of a sinking ship".

One metal chair with fabric components that has been painted white. This chair was part of the 185 Empty Chairs art installation which consisted of 185 different white chairs that represented those who died as a result of the Christchurch earthquake on 22nd February 2011.

Pipes lead into a shipping container. The photographer comments, "In Christchurch containers are so very versatile: They are used as barricades, supports, homes, shops, art galleries, artworks, Malls, pubs and bars, Thai takeaways and now sewage works".

Warning tape on the gate of a residential property near Cranmer Square. The photographer comments, "The yellow tape was put on the gate to warn property [owners] that the house beyond was unsafe. Now there is no house, but by the cobwebs on the handle the tape is doing a great job".

One circular metal and plastic badge featuring an image of a girl and the words 'We [heart] you Weng'. This personalised badge featuring an image of a girl and a personal message of love, was left at the site of the Canterbury Television (CTV) building after the 22 February 2011 earthquake. It was most likely left in commemoration of someone wh...

A demon mask hangs from a brick chimney in New Brighton. Some of the bricks at the base of the chimney appear to have moved. The photographer comments, "Since the September earthquake brick chimneys have been tumbling down. I do not know if this was put up to ward off shaking of the chimney during earthquakes, but it seems to be working. This chimney has now been taken down at the end of March 2012 and replaced with a simple metal flue".

A video of a tour through the Christchurch central city Red Zone. The video includes footage of Armagh Street, Madras Street, Latimer Square, St John's Anglican Church, Hereford Street, the Octagon Live restaurant, the Design and Arts building, the High Street mall, and the Grand Chancellor Hotel. It also includes footage of construction workers cutting up metal beams, and clearing rubble from a building on Manchester Street.

A damaged brick building on Tuam Street. Bricks have fallen from the wall exposing the interior, where a wooden structure can be seen to have collapsed. The photographer comments, "This is the damage caused by the numerous earthquakes in Christchurch, New Zealand. It closely resembles a face and the round blob in the square hole at the top of the nose is a pigeon".

The majority of Christchurch’s stormwater has historically been discharged untreated directly into urban surface waterways. These receiving waterways have become adversely affected by the contaminants carried in the stormwater, particularly sediment and heavy metals. An event-based contaminant load model was developed to identify the distribution and magnitude of contaminant loads entering the waterway, as well as to assess the reduction in TSS and heavy metal loads that can be achieved by various stormwater management options. The GIS-Excel based model estimates contaminant loads from an individual storm event based on different contributing impervious surfaces and key rainfall characteristics (rainfall intensity, duration, pH and antecedent dry days). It then calculates contaminant reduction loads that could be achieved through source reduction (e.g. green roofs, repainting) as well as from treatment (e.g. raingardens, wet ponds) applied to different surfaces within the catchment. This model differs from other annual load models as it is event-based and accounts for storm characteristics in its calculation of contaminant loads. Christchurch is a valuable case setting due the unique opportunity for retrofitting improved stormwater management in the post-earthquake rebuild. It is anticipated that this modelling approach could later be adapted for use in other urban settings outside of Christchurch.
