An aerial photograph of the Copthorne Hotel on Colombo Street. The photograph has been captioned by BeckerFraserPhotos, "When the PricewaterhouseCoopers building is demolished, the Copthorne Central Hotel will be alone on the block. Oxford on the Avon and Plunket House are also gone from Oxford Terrace, and on the other side of the river is the demolition site of the PGC building where 18 people died".

Brooklands Lagoon / Te Riu o Te Aika Kawa (‘Brooklands’) is an important wetland and estuarine ecosystem in Canterbury. It is a site of cultural significance to Ngāi Tūāhuriri, and is also valued by the wider community. Home to an array of life, it is connected to the Pūharakekenui/Styx and Waimakariri rivers, and is part of a wetland landscape complex that includes the Avon-Heathcote / Ihutai estuary to the south and the Ashley / Rakahuri estuary to the north. Notionally situated within the territorial boundary of Christchurch City Council and jurisdictionally encompassed by the regional council Environment Canterbury, it has been legally determined to be part of the coastal marine area. The complicated administrative arrangements for the lagoon mirror the biophysical and human challenges to this surprisingly young ecosystem since its formation in 1940. Here we present a synthesis of the historical events and environmental influences that have shaped Brooklands Lagoon. Before existing as an intertidal ecosystem, the Waimakariri river mouth was situated in what is now the southern end of the lagoon. A summary timeline of key events is set out in the table below. These included the diversion of the Waimakariri River mouth via the construction of Wrights Cut in the 1930s, which influenced the way that the lower reaches of the river interacted with the land and sea. A large flood in 1940 shifted the river mouth ~2 to 3 kilometres north, that created the landscape that we see today. However, this has not remained stable, as the earthquake sequence in 2010 and 2011 subsided the bed of the estuary. The changes are ongoing, as sea level rise and coastal inundation will place ongoing pressure on the aquatic ecosystem and surrounding land. How to provide accommodation space for Brooklands as an estuary will be a key planning and community challenge, as Environment Canterbury begins the engagement for the review of its Regional Coastal Plan. There is also a requirement to safeguard its ecological health under the 2020 National Policy Statement on Freshwater Management. This will necessitate an integrated mountains to sea (ki uta ki tai) management approach as the lagoon is affected by wider catchment activities. We hope that this report will contribute to, and inform these processes by providing a comprehensive historical synthesis, and by identifying considerations for the future collaborative management of Brooklands Lagoon, and protection of its values. In essence, we suggest that Te Riu o Te Aika Kawa deserves some sustained aroha.

Personnel from the USAID Disaster Assistance Response Team (DART) standing in Firefighters Reserve, in preparation for the two minutes of silence to honour the people who lost their lives in the 22 February 2011 earthquake. Just out of the picture is a sculpture fashioned from 5 tonnes of structural steel salvaged from the site of the World Trade Centre following their collapse on 11 September 2001 in terrorist attacks on New York City. The sculpture is now used as a tribute to firefighters in New Zealand.

A car stuck in a large pothole on River Road. The wheels on the right hand side of the car have fallen into the hole, leaving the car grounded against the road surface. The photographer comments, "This car belonged to a postal delivery worker - the NZ Post bike rack is mounted on the towbar. The owner must have biked home. Later a tow truck arrived to extract the car from the hole that had opened under its front wheel".

A badly damaged house in Burwood. Parts of the house have moved in different directions, leaving walls and doors misaligned. The photographer comments, "Although this looks like an extreme wide angle shot it is actually a house tilted in every direction at the same time. The earthquake caused the ground to vibrate and compress so much that the sandy soil liquefied and caused the ground to collapse under this modern home".

The "Tree of Hope" at the River of Flowers event held in Riccarton Bush, commemorating the second anniversary of the 22 February earthquake. The photographer comments, "Luggage labels and pens were supplied, and people were encouraged to write a message of hope for Christchurch and tie it to the tree. Although the turn-out this year was just as big as last year's, there were not as many messages tied to the tree - perhaps we're all feeling less hopeful this year".

Large cracks run through the brick cladding of this house in Wainoni. The photographer comments, "During the numerous earthquakes in Christchurch the land which ran alongside the Avon river on Avonside Drive slumped towards the waterway. Houses which were wooden framed and had an external brick veneer started to sink into the liquefied soil. This caused the brick walls to crack, but the houses' occupants though shook up were saved by the wooden framework from the houses collapsing on them".

Detail of damage to a house in Richmond. A double-brick wall has collapsed, and a gap is visible between the house and its foundation. The photographer comments, "These photos show our old house in River Rd and recovery work around Richmond and St Albans. The house and the concrete patio are now 15cm apart. The house took half the dining room's remaining bricks with it as it jumped off the foundations. It gives a good visual indication of the displacement".

Damage to a residential property in Richmond. The brick wall of the garage has collapse inward, and the roof fallen in on top of it. The photographer comments, "These photos show our old house in River Rd and recovery work around Richmond and St Albans. The neighbours behind us used the kayak to get in to their house - it's flooded by Dudley Creek which runs behind the block, plus major liquefaction. Our old garage provides a good spot to park it".

Detail of damage to a house in Richmond. A double-brick wall has collapsed. A wire loop which formerly tied the two layers of bricks together has pulled out from one of the layers, showing how the two parts of the wall moved apart during the shaking. The photographer comments, "These photos show our old house in River Rd and recovery work around Richmond and St Albans. The remaining double brick by the back door has been further smashed and twisted".

This literature review uses research informed by disasters including the Christchurch Earthquakes, Hurricane Katrina, Red River floods, War in Israel and natural disasters in Indonesia to identify key aspects within teacher-student relationships which result in an increase in the emotional stability of our students. These aspects include prior knowledge of students and their development, psycho-social interventions and incorporation of the disaster into the curriculum. Teacher-student relationships are highlighted as vital to a child’s healing and resilience after experiencing disaster trauma.

In the aftermath of the 2010-2011 Canterbury Earthquake Sequence (CES), the location of Christchurch-City on the coast of the Canterbury Region (New Zealand) has proven crucial in determining the types of- and chains of hazards that impact the city. Very rapidly, the land subsidence of up to 1 m (vertical), and the modifications of city’s waterways – bank sliding, longitudinal profile change, sedimentation and erosion, engineered stop-banks… - turned rainfall and high-tides into unprecedented floods, which spread across the eastern side of the city. Within this context, this contribution presents two modeling results of potential floods: (1) results of flood models and (2) the effects of further subsidence-linked flooding – indeed if another similar earthquake was to strike the city, what could be the scenarios of further subsidence and then flooding. The present research uses the pre- and post-CES LiDAR datasets, which have been used as the boundary layer for the modeling. On top of simple bathtub model of inundation, the river flood model was conducted using the 2-D hydrodynamic code NAYS-2D developed at the University of Hokkaido (Japan), using a depth-averaged resolution of the hydrodynamic equations. The results have shown that the area the most at risk of flooding are the recent Holocene sedimentary deposits, and especially the swamplands near the sea and in the proximity of waterways. As the CES drove horizontal and vertical displacement of the land-surface, the surface hydrology of the city has been deeply modified, increasing flood risks. However, it seems that scientists and managers haven’t fully learned from the CES, and no research has been looking at the potential future subsidence in further worsening subsidence-related floods. Consequently, the term “coastal quake”, coined by D. Hart is highly topical, and most especially because most of our modern cities and mega-cities are built on estuarine Holocene sediments.

A photograph looking north down Gayhurst Road, taken from the side of the bridge over the Avon River. Residential properties used to line the left-hand side of the road, and St Paul's church once stood on the corner. This was before the land was red-zoned as a result of the 2010 and 2011 Canterbury earthquakes. Separated cycle ways have recently been installed on both sides of the road. The photograph was modelled off an image taken by Mark Lincoln in September 2010.
