Room for the river: Is it time to re-think how we manage floods?
www.rnz.co.nz
Since the 1950s, the Ngaruroro River in Hawke’s Bay has been steadily and deliberately restricted to a channel half its former width. As the likelihood of extreme flooding increases, is it time to re-imagine the river’s future?

This is pretty interesting! I like the bits where they show the 1950s aerial view vs the present ones to show how the river changed.

    Yeah I spent a day helping clear up at an orchard after Gabrielle and there was a whole field where some younger trees were all just gone. I think what had happened in a lot of places was debris from upstream just washed through at velocity and broke everything above ground level away then pushed it down until it hit a barrier it couldn’t get over or around.

    And in some places, where that barrier was a bridge the weight of water & debris was enough to wash that away too.
