Managed Retreat vs the Metrotidal Urban Orbital is a case for debate as part of the current 10-year flood defence review of the Thames and Medway estuaries and for the run up to COP26, the 2021 UN Climate Change Conference in Glasgow. Here the Clyde provides a useful demonstration, with a lower tidal range than many other UK urban estuaries but still some 3m with storm surges, where a relatively short flood defence line across the outer estuary protects a large urban area and improves urban and coastal connectivity.
Current investment policies for coastal flood defences, urban rail, micro-mobility, data connectivity, FTTP, freeports, the levelling-up of the North and the strengthening of the Union are all addressed with lower cost and carbon audit by the Metrotidal Urban Orbital and its application to urban estuaries around the UK.
