A dam is supposed to prevent substantial issues for locals.
However, when an iconic dam in Europe was filled, it submerged an entire island and forced the local populace to relocate. The river around the dam saw its water level rise almost uncontrollably, creating an unforeseen effect that played a key role in and around the region.
How can a dam built to control a river have such an adverse effect on the locals?
How dams around the world affect the planet we live on
Dams are a feature of mankind’s progression over thousands of years.
The very first human-made dam on record was the Jawa Dam in Jordan. Geologists have dated it back to somewhere between 3000 and 3200 BC. It laid the foundation for similar projects to be undertaken over the next few thousand years.
Even the Earth’s rotation has been affected by the construction of dams around the world.
The Three Gorges Dam in China is huge. It holds back approximately 42 billion tons of water. It has actually shifted the Earth’s mass so much that it slowed the planet’s rotation by 0.06 microseconds, as well as moving the North Pole by roughly 2 cm.
The hidden blueprint: How humanity is accidentally redrawing the Earth
Our collective impact on the Earth has been profound, to say the least.
A hydroelectric dam in the iconic Golden State changed the flow of a river and forced the evacuation of a huge fish hatchery. Proving that, without pragmatic planning and forethought, some human-led projects can devastate parts of the world in ways we never expected.
You might say it was ambitious of us humans to think we could control waterways on Earth.
The world is changing in more ways than we ever could have thought possible. Such as how oyster farmers in Hiroshima are finding the vast majority of their harvest turning up dead.
If the world can not address the effects of climate change on the planet, we are in for a bumpy next few decades, to put it mildly.
NASA has enabled scientists around the world to study the planet and all its wondrous features in great detail. And when NASA turned its attention to the Iron Gate Dam in Europe, it found that an entire island had vanished.
How a massive dam forced the relocation of thousands of residents
The Iron Gate Dam system is located in Eastern Europe, specifically between the border of Romania and Serbia.
Iron Gate Dams 1 and 2 were constructed on the Danube River, which is the second-longest river in Europe. The elongated gorge system of the dams cuts across the Carpathian Mountains in Romania and the Balkan Mountains in Serbia.
Dams and reservoirs play a key role in providing water and energy for the local population, but this one had a somewhat unexpected effect.
How an “Fortress Island” vanished near the Danube River
The island of Ada Kaleh, which is Turkish for “Fortress Island”, was a small and historic island in the Danube River. It was flooded in 1971 when the Iron Gate Dam was constructed, forcing about 1,000 people from the Turkish enclave to relocate.
The island was one of the last territories of the Ottoman Empire, officially becoming part of the nation of Romania in 1923.
The Iron Gate dam project raised the Danube River’s water level by approximately 131 feet, which completely submerged the Ottoman enclave and forced the people who were still living there to relocate.
The infrastructure also disrupted fish migration routes and altered navigation by calming the treacherous waters around the river.
So while our collective impact on the planet is becoming all too clear as natural weather events devastate parts of the world, we now understand that this human-led alteration of the Danube River has adversely impacted a unique group of people in the region.
