A "Stuff" illustrated story and podcast - an enlightening point-of-view. When read with a cadastral surveyor hat on, I wonder what downstream (excuse the pun) boundary issues this may create? Aotearoa New Zealand’s braided rivers are internationally significant, but they’ve been systematically strangled. As climate change threatens to make the problem worse, some academics and scientists are re-imagining what it means to live with rivers.Stuff Interactives: 26-June-2021

How 19 words thwarted efforts to save our shrinking braided rivers Stuff - Environment: 8-April-2023It’s a deceptively complicated question: What is a riverbed? The quest for an answer has pitted science against the law, leaving some of the country’s most iconic rivers in danger and a diverse group of scientists, academics and environmentalists lobbying for a resolution. The Blythe River was always small, but it only started shrinking recently. The terraces that mark its natural boundaries, carved deep into the land, have greened; its scrubby, frayed edges are smooth. Where it once split into braids, a newly built flood control barrier forces the river to a single channel. A decade ago, the river’s margins had a footprint of about 44ha. Today they cover around 9ha – a decline of 80% And to cut to the chase - the nineteen words being the definition of “riverbed": “The space of land which the waters of the river cover at its fullest flow without overtopping its banks”.This definition, critics say, is difficult – and, in some cases, impossible – to apply to a braided river.
