What are some major natural changes in geography that have happened within the timespan of recorded history? The following come to mind:

>Persian Gulf shrinking
>End of the India-Ceylon land bridge
>Decline of the Great Rann of Kutch
>Many changes to river courses, but most notably the Yellow River's wandering mouth
>Separation of the North Judlandic Island
>Shifting coastlines in marshy regions

Shrinkage of the Aral - and in relation of the changes of Oxus and Jaxartes.

Aral sea problem was popular theme even in 80s. No one wanted to ruin Central Asian economics by removing irrigation though, so there were only discussions without action.

After dissolution of USSR nothing changed, and now "sea" is almost nonexistent.

But the Aral Sea's decline was the effect of human action. I was thinking about changes with natural causes.

Speaking of the Oxus, there's evidence that some or all of it drained into the Caspian in the past.

>I was thinking about changes with natural causes.
Ah. I'll think about it more than.

>Speaking of the Oxus, there's evidence that some or all of it drained into the Caspian in the past.
Yes, that area - Khorezm, Sogdiana - was very different in earlier times. There are historical misunderstandings due the position of the Oxus as well.

Taipei lake was recorded in 17th century and now the lake is no where to be found.

Still haven't thought about it but maybe some catastrophic event, an earthquake or volcano eruption made stuff different.
The Great Hungarian Plain has some desertification as well but not sure the causes how much caused by human activity.

I guess that Litte Ice Age must have some geographical consequences, but there is no easy googled list.

Bumping thread for interest.

I assume that the Panama canal could count as a geographic change.
Also the diversion of the Colorado river, which used to irrigate large chunks of Mexico but now most of the downstream flow stays in American farms.

Receding ice? The northwestern passage is opening up.

>Tuzla Island was formed when the spit that continued the Taman peninsula suffered from massive erosion during a major storm in 1925.[2] In ancient times (2,500 years ago) the sea level was 4 meters below the present, which meant that at the site of modern Tuzla was quite an extensive area of land, which was part of the Taman Peninsula. Taman Peninsula itself at that time was part of the Kuban delta, and was separated from the rest of the land by river channels, which fell into the Sea of Azov and the Black Sea. Some historians identify Tuzla as the island of Alopeka, mentioned among the ancient authors, located in the waters of Cimmerian Bosporus, and when the island periodically joined to the Asian shore of the Bosporus, the resulting braid was used as the entrance to the passage through the narrowest part of the Cimmerian Bosporus, which is located between Alopekoy and the European shore of the Bosporus. Other historians and geologists reject such a hypothesis, believing that neither the island nor the Tuzla Spit existed in ancient times.

The time for solution was long past, now central asia is even drier than it supposed to be. It's a massacre of natural balance that's what it is.

>What are some major natural changes in geography that have happened within the timespan of recorded history?
there was an island in northwest of ireland it's nowhere to be found
