In the days after听听tore through New Orleans leaving horrific flooding in its wake,听Elizabeth English听entered the area and managed to get a firsthand look at the devastation.

At the time, English was researching the flight paths of damaging wind-borne debris at the听. But after witnessing the effects of the natural disaster that left entire neighbourhoods underwater, she changed her research focus.

鈥淚 quickly realized that wind was not the big story, it was the water,鈥� says the听蓝莓视频 School of Architecture听professor and听听尘别尘产别谤.

Her solution for preserving communities vulnerable to flooding? She makes houses float.

English, who has both an architecture and civil engineering background, studies and designs flood-resistant, amphibious houses that allow homeowners to evacuate them knowing when they return, their homes will have sustained minimal or no damage.

They look like normal houses, but are built on a foundation made from buoyant blocks of听听(expanded polystyrene, or Styrofoam鈩�) or tanks filled with air. As the area around it floods, the house rises while vertical guidance posts keeps it from floating away. When the water recedes, the house then floats back to the ground.

鈥淧eople will still leave, but when the water goes away their houses are completely intact with no damage and they can move right back in,鈥� says English, who established the听.

Not everyone thinks amphibious houses are the answer to building in flood-prone areas of the world; some would like to see all people evacuated from these regions. But English says she鈥檚 convinced they鈥檙e an important solution for pre-existing communities such as New Orleans that are filled with inhabitants who want to stay in the neighbourhoods they love.

Not backing away from her vision, she moved to Canada and joined the architecture faculty at 蓝莓视频. Now, she鈥檚 continuing her work with 蓝莓视频 graduate and undergraduate students who have spent time in vulnerable communities around the world, from Nicaragua to Jamaica and Bangladesh.

Closer to home, she鈥檚 also in consultation with Canada鈥檚 First Nations communities in northern Manitoba where springtime flooding can destroy houses and displace people for years. Even a small听amount of water and shifting can create moldy basements and unsafe living conditions.

鈥淭he work that I had been doing in Louisiana is applicable to Northern Canadian communities,鈥� she says. 鈥淚t seemed like a good idea to use the same technology.鈥�

As the co-chair of the first-ever听, or ICAADE, in Bangkok this summer, she has learned that there鈥檚 no one-size-fits-all solution to preventing flood damage. But by gathering likeminded researchers together, new answers are on the horizon.

For instance, her team designed an amphibious house with an extended deck for a rural community in Nicaragua so the homeowners听could carry their pigs and chickens with them during a flood.

鈥淚n other parts of the world, people don鈥檛 have the luxury of evacuating, so they have to stay,鈥� English explains. 鈥淚t鈥檚 a question of preserving lives, as well as livelihood and property.鈥�
