Scientists find cause for rise in urban flooding

Published

Scientists at the University of South Florida’s College of Marine Science investigating the increasing risk of ‘compound flooding’ for major US cities have found that flooding risk is greatest for cities along the Atlantic and Gulf coasts when strong storm surge and high rainfall amounts occur together.

While rising sea levels are the main driver for increasing flood risk, storm surges caused by weather patterns that favor high precipitation exacerbates flood potential.

“Nearly 40 percent of the U.S. population resides in coastal counties,” said study lead author Thomas Wahl of the University of South Florida College of Marine Science and the University of Siegen in Germany. “Flooding can have devastating impacts for these low-lying, densely populated and heavily developed regions and have wide-ranging social, economic and environmental consequences.”

Their analysis focused on the joint occurrence of the two distinct flooding sources in coastal regions – storm surge and high precipitation – that can result in direct run-off (pluvial) and increased river discharge (fluvial).

The research team also identified three key compound flooding mechanisms: elevated water levels in estuarine regions; storm surge flooding that worsens with heavy rainfall and; moderate storm surge that blocks or slows down drainage.

They concluded that “the complex interplay between storm surge and precipitation can lead to, or exacerbate, the impacts of flooding in coastal zones through multiple mechanisms.”

“Whether or not all of these mechanisms are relevant at a particular site strongly depends on the local setting,” explained Wahl who, along with colleagues from the University of South Florida (USF), the University of Maine, and the University of Siegen, in Germany, collected and analyzed data sets for storm surge and rainfall for over 30 American cities along the Atlantic, Gulf and Pacific coasts. Their analysis included many of the 17 U.S. port cities with populations over one million, for which the occurrence of compound flooding had not been previously assessed.

Armed with data reaching back into the 1950s, and some data from the beginning 20th century for some sites, they determined that the risk for compound flooding was higher for cities along the Atlantic and Gulf coasts than for those on the Pacific coast. Consequently, they looked more closely at selected regions along the Atlantic coast.

When they analyzed the data specific for New York City in greater detail, the researchers determined that storm surges in New York City (where compound flooding events are increasing) are accompanied by heavy precipitation when a high pressure system stretches from Newfoundland south over the North Atlantic from where moist air is transported into the low-pressure system causing the storm surge. They also noted that the extreme flooding in that region during “Hurricane Sandy” in 2012 was the result of extreme storm surge but that the rainfall during that storm was (fortunately) “small in the historical context for such an event.”

Overall, they found that the number of compound flooding events has been steadily increasing over the past century along many stretches of coastline.

“Our results demonstrate the importance of assessing compound flooding and its links to weather and climate, but we need more research at local scales to determine impacts,” concluded Wahl and his colleagues. “That research will require complex, integrated modeling experiments that investigate surface and drainage flows and include storm surge, rainfall and river discharge. In light of climate variability and change, it will be important to develop a detailed understanding of future patterns of storm surge and high precipitation amounts occurring in tandem.”

Modern day society is becoming ever more conscious about the effects of human consumption on the environment & the planet.

As a collective, more people are considering taking action to positively counteract their environmental footprint. This is accomplished by cutting down on water consumption, recycling and switching from plastic to more sustainable materials. Although most people forget about the additional things that can be done at home to improve your individual eco footprint.

Appliances, for example, can be overlooked when it comes to helping the environment, despite the fact they are items which are found in every household, and if they are not maintained effectively they can be detrimental to the environment. The longer an appliance is used, the less of an impact it has on the environment, so it is essential for you to keep them well maintained.

If you’re considering becoming more eco-conscious, here are 5 handy appliance maintenance tips to help you.

Don’t Forget to Disconnect From Power First

General maintenance of all your appliances start with disconnecting them from power; microwaves, washing machines and ovens all use residual energy when plugged in, so it’s essential to unplug them.

Disconnecting the plugs can help keep them in their best condition, as it ensures no electrical current is running through them whilst they are supposed to be out of use. Additionally, this can help you save on energy bills. By doing this you are minimising your energy footprint.

Here we break down 4 tips to keep the most popular household appliances maintained.

Eco-Friendly Oven Maintenance

Ovens generally require very little maintenance, although it is essential to stay on top of cleaning.

A simple task to make sure you don’t have any issues in the future is to check the oven door has a tight seal. To do this ensure the oven is cold, open the oven door and use your hands to locate the rubber seal. You can now feel for any tears or breaks. If any have occurred simply replace the seal. More oven tips can be read here.

Eco-Friendly Refrigerator Maintenance

When keeping a fridge in good condition, don’t forget about exterior maintenance. Refrigerator coils, although an external fixture, can cause damage when overlooked.

Refrigerator coils can be found either at the front or rear of a fridge (check you user manual if you are unsure of its location). These tend to accumulate various sources of dust and dirt over a substantial time-period, which clog refrigerator coils, causing the refrigerator to have to work twice as hard to stay cool. An easy tip to solve this is to periodically use a vacuum to get rid of any loose dirt.

Eco-Friendly Washing Machine Maintenance

Most people tend to remember the basics tasks for maintaining a washing machine, such as not to overload the machine, not to slam the door and to ensure the washing machine is on a solid and level platform.

In addition, it is necessary to routinely do a maintenance wash for your washing machine. This means running an empty wash on the highest temperature setting and letting it complete a full wash to erase any build up and residue. You should repeat this task at least once a month.

Try to schedule this task around your bulk wash load times to save on water consumption.

This will help keep your washing machine in peak working condition.

Eco-Friendly Dishwasher Maintenance Tips

Dishwasher maintenance can be simple if implemented after every wash cycle.

To keep your best dishwasher hygiene standards, scrape away excess food whilst making sure to keep the filter at the bottom of the cavity empty between cycles. This simple task can be highly effective at preventing food build up from occurring in your dishwasher.

If you need additional tips or tasks you, can reference your manufacturer’s guidebook to check for a full breakdown. You can also head to Service Force’s extensive database of repair and maintenance manuals – including extensive troubleshooting guides for all of the critical appliance maintenance procedures.

In conclusion, you can save both money and energy by keeping your appliances in peak condition. The steps outlined in this guide will help us all preserve the environment and reduce industrial waste from discarded appliances.

Two Ancient Japanese Philosophies Are the Future of Eco-Living

Published

Our obsession with all things new has blighted the planet. We have a waste crisis, particularly when it comes to plastic. US scientists have calculated the total amount of plastic ever made – 8.3 billion tons! Unfortunately, only 9% of this is estimated to have been recycled. And current global trends point to there being 12 billion tons of plastic waste by 2050.

However, two ancient Japanese philosophies are providing an antidote to the excesses of modern life. By emphasizing the elimination of waste and the acceptance of the old and imperfect, the concepts of Mottainai and Wabi-Sabi have positively influenced Japanese life for centuries.

They are now making their way into the consciousness of the Western mainstream, with an increasing influence in the UK and US. By encouraging us to be frugal with our possessions, (i.e. using natural materials for interior design) these concepts can be the future of eco-living.

What is Wabi-Sabi and Mottainai??

Wabi-Sabi emphasizes an acceptance of transience and imperfection. Although Wabi had the original meaning of sad and lonely, it has come to describe those that are simple, unmaterialistic and at one with nature. The term Sabi is defined as the “the bloom of time”, and has evolved into a new meaning: taking pleasure and seeing beauty in things that are old and faded. 

Any flaws in objects, like cracks or marks, are cherished because they illustrate the passage of time. Wear and tear is seen as a representation of their loving use. This makes it intrinsically linked to Wabi, due to its emphasis on simplicity and rejection of materialism.

In the West, Wabi-Sabi has infiltrated many elements of daily life, from cuisine to interior design. Specialist Japanese homeware companies, like Sansho, source handmade products that embody the Wabi-Sabi philosophy. Their products, largely made from natural materials, are handcrafted by traditional Japanese artisans – meaning no two pieces are the same and no two pieces are “perfect” in size or shape.

Mottainai

Mottainai is a term expressing a feeling of regret concerning waste, translating roughly in English to either “what a waste!” or “Don’t waste!”. The philosophy emphasizes the intrinsic value of a resource or object, and is linked to hinto animism, the notion that all objects have a spirit, or ‘kami’. The idea that we are part of nature is a key part of Japanese psychology.

Mottainai also has origins in Buddhist philosophy. The Buddhist monastic tradition emphasizes a life of frugality, to allow us to concentrate on attaining enlightenment. It is from this move towards frugality that a link to Mottainai as a concept of waste can be made.

How have Wabi-Sabi and Mottainai promoted eco living?

Wabi-Sabi is still a prominent feature of Japanese life today, and has remained instrumental in the way people design their homes. The ideas of imperfection and frugality are hugely influential.

For example, instead of buying a brand-new kitchen table, many Japanese people instead retain a table that has been passed through the generations. Although its long use can be seen by various marks and scratches, Wabi-Sabi has taught people that they should value it because of its imperfect nature. Those scratches and marks are a story and signify the passage of time. This is a far cry from what we typically associate with the Western World.

Like Wabi Sabi, Mottainai is manifested throughout Japanese life, creating a great respect for Japanese resources. This has had a major impact on home design. For example, the Japanese prefer natural materials in their homes, such as using soil and dried grass as thermal insulation.

Their influence in the UK

The UK appears to be increasingly influenced by thes two concepts. Some new reports indicate that Wabi Sabi has been labelled as ‘the trend of 2018’. For example, Japanese ofuro baths inspired the project that won the New London Architecture’s 2017 Don’t Move, Improve award. Ofuro baths are smaller than typical baths, use less water, and are usually made out of natural materials, like hinoki wood.

Many other UK properties have also been influenced by these philosophies, such as natural Kebony wood being applied to the external cladding of a Victorian property in Hampstead; or a house in Lancaster Gate using rice paper partitions as sub-dividers. These examples embody the spirit of both philosophies. They are representative of Mottainai because of their use of natural resources to discourage waste. And they’re reflective of Wabi-Sabi because they accept imperfect materials that have not been engineered or modified.

In a world that is plagued by mass over-consumption and an incessant need for novelty, the ancient concepts of Mottainai and Wabi-Sabi provide a blueprint for living a more sustainable life. They help us to reduce consumption and put less of a strain on the planet. This refreshing mindset can help us transform the way we go about our day to day lives.
