泰晤士河。考慮修建防洪堤時發現稀有物種

它是蜉蝣Caenis beskidensis,已經49年沒有在英國出現過了。

它是在泰晤士河計劃的早期工程中被發現的,當局希望該計劃能改變薩里和倫敦西南部的部分地區。

埃厄姆和泰丁頓之間的泰晤士河是英格蘭最大的無防衛洪泛區之一。

這裡有大約11000個家庭和1600個企業,正如該地區在2014年發現的那樣,它很容易受到極端洪水的影響。

然後,泰晤士河決堤,整個社區被淹沒在水中。這對許多人來說是毀滅性的。

八年後的今天,當局希望他們已經想出了一個解決方案。

它被稱為泰晤士河計劃,它所做的是創建兩個巨大的水渠,使洪水可以被分流。

這些水渠基本上連接了現有的湖泊,可以作為洪水的容量。

隨着氣候變暖,科學家們認為極端天氣和山洪爆發將變得更加普遍,因此這些計劃更加重要。

當局希望它們也能創造綠色、生物多樣性的栖息地,並讓當地人有機會獲得綠色空間。


It is the mayfly Caenis beskidensis and hasn't been seen in the UK for 49 years.

It was discovered as part of the early works of the River Thames Scheme which authorities hope is going to transform parts of Surrey and south-west London.

The River Thames between Egham and Teddington is one of the largest areas of undefended, floodplains in England.

There are about 11,000 homes and 1,600 businesses and as the area found out in 2014, it is vulnerable to extreme flooding.

Then, the Thames burst its banks and whole communities were submerged in water. It was devastating for many.

Now eight years later, the authorities hope they have come up with a solution.

It is called the River Thames Scheme and what it does is create two huge water channels that flood water can be diverted into.

The channels essentially link up existing lakes which can be used as capacity for flood water.

With a warming climate, scientists think extreme weather and flash flooding will become more common and so these schemes are even more essential.

The authorities hope that they will also create green, biodiverse habitats and give local people access to green space.
