Calling for Christchurch flood photos

The flooding that Christchurch experienced on Wednesday was extreme, leaving many houses flooded and roads closed. To build a better understanding of how vulnerable different parts of Christchurch are to flooding in the future, particularly following the earthquakes, we would like your help.

If you took any photos at or near peak water levels anywhere in Christchurch during Wednesday morning or early afternoon, please send them to NIWA (floodphoto AT niwa.co.nz)* with the street address and time, and with the subject “Flood”.

We will use the images to help identify how high the waters rose across the city. This will help us improve our models so we can provide better flood risk maps in the future.

* The NIWA email is once again working. Sorry for any inconvenience.

Update 16 June 2014: The results are in.

  • Hi,

    I have about 27 photos taken around midday around the block bordered by banks ave (where Dudley creek meets the Avon), River Rd, Medway St and Woodchester Ave. Also we have some from later in the afternoon that my partner took from around various areas probably Shirley. I’m planning to markup a map for the ones that I have for the block mentioned above as we will use them for something else. Do you want this? The photos my partner took are from all around Shirley with a few in town I think, do you want these?

    Regards Jeff

  • Thanks Tracey, that’s great.

    Jeff, your midday photos would be great, but the late afternoon Shirley ones are less useful for our purpose, as that area peaked earlier in the day. We’re trying to map things around the time of the maximum inundation. Thanks! [DC]
