Waterways were once the beating hearts of our cities.
They bore the boats laden with the goods, tradesmen and settlers that transformed inlets and backwaters into hubs of humanity. However, all that changed 200 years ago with the advent of the industrial revolution: as cities became crowded, rivers were polluted with human and industrial waste, becoming sources of disease; at the same time the development of the railways meant waterways were no longer the essential mode of transport they once were. The result was that all across the world cities covered over their rivers, forcing them into culverts or tunnels below the metropolis. Today, waterways across the world are fighting back. In a trend known as “daylighting”, towns in Europe, Asia, North America and Australasia are breaking open culverts to reveal the hidden rivers that have always been at their heart. The two most active cities by far have been London and Zurich.

Porter Brook is a “pocket park” – a small amphitheatre, sloping down to the banks of the river Porter, where wild trout spawn in spring and students from the technical college picnic and paddle. Two years ago, the pocket park did not exist. There was just a crumbling car park with the river Porter nowhere to be seen, save for a brief glimpse before it disappeared into a culvert. “There’s no green spaces at all in this part of Sheffield, so the pocket park has been a great success,” says Katie Bayliss, a local resident. “Before, I don’t think people realised there was a fully flowing river here. *****Dams and weirs - problems: Geomorphology of a river: what happens when you install a dam & how the sediment transport changes.

Flood defence plans heavily favour London and south-east. The government’s planned spending on flood defences heavily favours London and the south-east of England, according to a new analysis, with spending per person up to 13 times higher than in other regions.
The recently published plans set out spending to 2021 and, for major projects, beyond that date. By far the largest projects are those for the Thames estuary, leading to 60% of the planned spending going to London and south-east, home to 32% of England’s population. Accusations of a north-south divide in flood defence spending were dismissed by then prime minister David Cameron after severe floods across northern England in December 2015. But the new research indicates southern areas will receive significantly more money. It was conducted by analysts at Carbon Brief and takes into account the £700m funding boost announced after those floods. The new analysis assesses the funding in place until 2021 and also the anticipated spending on large projects that will completed after that date.

Mélanie Vallui and Laureline Gérard created this story map to educate school children about flood risk. The French have long dealt with devastating floods, one of the worst being the so-called Great Flood of Paris in 1910. However, French residents need to be better informed about the risks of major floods, according to university students Mélanie Vallui and Laureline Gérard. Complete Flood Management with ArcGIS.

Image copyright AFP Half of all the money earmarked for new flood defences in England will be spent on protecting London and areas around the Thames, official figures show.
Analysis by BBC News has found £1.8bn will be spent on the Thames Estuary out of a £3.7bn national flood spending programme. About 16,000 homes were flooded across the North of England a year ago. The Environment Agency said it invested money "where it will have the most benefit". The disparity in regional flood defence spending comes as many flood victims remain homeless, 12 months after storms Desmond and Eva devastated parts of Yorkshire, Lancashire and Cumbria. One in 10 new homes were created in areas of high flood risk last year. Flood Afghanistan bring woods from high mountains to villages. it is amazing. #Paktya #Paktia #Khost.
Megadams: Brazil's Environmental Agency Halts 8-GW Amazon Hydropower Project. Brazil’s environmental protection agency, IBAMA, in early August canceled development permits for an 8-GW hydroelectric project on concerns about its social and ecological impacts.
Megadams: Brazil’s government charged with ethnocide in building of Amazon dam. Brazil’s Public Federal Ministry (Ministério Público Federal, MPF), an independent state body, has started legal proceedings to have it recognised that the crime of “ethnocide” was committed on seven indigenous groups due to the severe detrimental impacts on their lives made by the building of the giant Belo Monte hydroelectric power station that will soon begin operating on the Xingu River in eastern Amazonia. The charges have been made against Brazil’s federal government and Norte Energia, the contractor that built the dam.

UK flooding: How a Yorkshire town worked with nature to stay dry. While the sodden, submerged North of Britain was, literally, wringing out the old year last week, one notorious Yorkshire flood blackspot was celebrating staying dry – despite having been refused a multimillion pound defence scheme. Pickering, North Yorkshire, pulled off protection by embracing the very opposite of what passes for conventional wisdom. On its citizens’ own initiative, it ended repeated inundation by working with nature, not against it.
Its success, and that of similar schemes across the country, should be at the heart of the “complete rethink” of policy being officially promised in the aftermath of last month’s floods – which cost the country at least £5 billion – as climate change threatens to make them increasingly commonplace. Time to restore nature's flood defences. The Wildlife Trusts are calling on UK Governments to invest in natural solutions to control flooding Storms and flooding have caused significant damage across the UK, and climate change is likely to increase the frequency of such extreme weather in the future, costing Governments and taxpayers millions and devastating communities and businesses. Now is the time for UK Governments to prioritise investment in wilder landscapes to provide the natural solutions so badly needed to help prevent flooding in future The Wildlife Trusts believe that now is the time for UK Governments to prioritise investment in wilder landscapes which could provide the natural solutions so badly needed to help prevent flooding in future.
*Soft engineering: UK government not funding natural flood prevention methods. Natural ways of preventing flooding such as planting trees have no government funding despite ministers repeatedly backing the idea, according to a freedom of information request by Friends of the Earth. Almost a year since devastating floods hits swathes of northern Britain, environment secretary, Andrea Leadsom, and floods minister, Thérèse Coffey, have both recently supported the approach, which aims to slow the flow of water off hills and reduce peak levels. But the Department of Environment, Food and Rural Affairs (Defra) told Friends of the Earth (FoE) that “there is no funding earmarked specifically for natural flood management”.
The response came shortly after a cross-party committee of MPs concluded earlier this month that natural ways of stopping floods must be a key part of protecting the nation as climate change intensifies rain storms.

Six ways city landscapes can be more flood resilient - in pictures. *SuDS MPs endorse landscape work for flood mitigation. The House of Commons Environment & Rural Affairs Committee last week called for a large-scale - in the region of 100-200sq km - catchment trial of natural flood-risk management approaches, including leaky dams, tree planting and improved soil measures, alongside using farmland to store water as is done in the Netherlands, with Defra and the NFU to work together with "appropriate incentives to recompense farmers".
The report acknowledges that the Government has increased funding for flood risk management but points out that the money "was unlikely to deliver sufficient protection in future decades". It says hard engineering solutions cannot solve the problem alone and recognises the part landscape can play, including the role of urban parks as temporary water storage areas and trees' ability to soak up water. *Sustainable drainage SuDS.
