Recent floods in the UK are a strong reminder of the urgency of our climate changing.
And the need for the revision of the current flood defences and how we can, if not avoid, then, at least, take appropriate mitigating measures to minimise the floods.
Flood also happened in Venice. Italy is already dealing with unsustainable tourism which affects the infrastructure. The tides from Adriatic sea flooded St Mary's Square and St Mark's Basilica, the most precious sites.
GPS and radar images suggest that the part of city are gradually sinking. The Venice’s flood defence system, Mose project, is going to be completed in 2021.
Yorkshire, Derbyshire, Nottinghamshire, Lincolnshire, North Midlands and Gloucestershire are among the areas affected. River Severn and river Avon have swollen.
Coventry ‘s principle rivers, Sowe and Sherbourne have risen, too. However they haven't reached the point where there is a risk of flooding.
The results of the weather conditions are evident while walking along the river Sowe toward Ansty Road. The river clearly can’t cope, is overflowed and as a result the surrounding grounds are saturated with water (as seem in pictures).
Conventional methods such as drainage system, reservoirs, pumping water out, should be combined with more innovative mathods to deal with a crisis more effectively. Especially, it is important to take into consideration the climate changes as a compelling reason to take more drastic measures.
Remeandering straightened rivers could restore rivers to their natural courses. Halting deforestation and leaving the green area intact and help biodiversity. Restoring wetlands would reduce the impact of climate change.
Floods on streets of Birmingham were surface floods. Ageing sewage infrastructure no longer can help in intense urban areas. Some modern solutions are required.
SuDS, Sustainable urban Drainage System offers ways of dealing with surface water flooding. Attenuation craters dissipate water into the lower ground minimising risk of run off. Eco Blocks have high volume infiltration storage compared with a standard gravel infiltration ditch.
Pluvial flood management should be implementing green and blue areas round the living spaces, repaving pavements to create more permeable greener streets.
Allowing landscape architects design our urban areas and not only traffic engineers. Creating sponge cities where water can be reused during draught and soaked up during storms.
Causes of surface water flooding can be a result of the wrong way of farming as reported with Maize.
Maize production increased due to its use in Anaerobic Digestion plants. The soil is compacted, it can’t absorb the water and as a result create run offs what cause floods and pollute watercourses.
New developments should be laid out in a way which reduce surface water and other risks. Milton Keynes is an example of decentralisation by creating green and blue spaces around urban areas. It enhances habitat, improve water quality, greater biodiversity and quality of living.
Worrying is the fact that flood prone local authorities propose building homes in a high risk areas. Unfortunately, the Environment Agency can only write recommendations and council has no obligation to go along with them. The area affected are Boston United Football Club, Sheffield and Doncaster. It is council's responsibility when it comes to approval of proposals to build in high risk areas.
It is important to raise awareness without it NO right or adequate action can ever be taken.
