Guyana Langscape Over Time

This map shows the Essequibo River Drainage Basin and
the various rivers that flow through Guyana. exemplifying
Guyana's fluvial landscape. 

Being named the Land of Many Waters, Guyana’s landscape is very much Fluvial. Fluvial is a term used in to refer to the processes associated with rivers and steams including the deposits and landforms created by them. Guyana can be divided into five natural regions; a narrow and fertile marshy plain along the Atlantic coast (low coastal plain) where most of the population lives; a white sand belt more inland (hilly sand and clay region), containing most of Guyana's mineral deposits; the dense rainforests (Forested Highland Region) in the middle of the country; the grassy savannahs in the southern west; 
the larger interior highlands (interior savannah) consisting mostly of mountains that gradually rise to the Brazilian border. 

1,000 years from the towns and villages in Guyana will be run down and decaying if not destroyed by weathering and flooding. Every year the rains flood the savannah. In many areas it is possible to move about only by boat during this season.

The above image shows the Rupununi, the grassy savannahs in the
southern west hemisphere of Guyana. Rupununi is an area of dry
grasslands with sparse trees, termite mounds and wooded hills.

Guyana, having one of the largest unspoiled rainforests in South America, some parts of which are almost inaccessible by humans. Approximately eight thousand species of plants occur in Guyana, half of which are found nowhere else. With more than 80% of Guyana being covered by rain forests, ranging from dry evergreen and seasonal forests to montane and lowland evergreen rain forests. I suspect in 10,000 the rain forest that occupies Guyana will grow and spread across the area of Guyana and cover 100% of the land. As the years go by the Tepui tabletop mountains in Guyana will slowly start to grow in height due to upward faulting and frosty weather. Seeing as the Tepui mountains have grown from In 10,000 years the Tepui would grow over 10,000 ft in height. By this time the roads would be flooded and washed out do to the amount of rainfall in the area. Further more, 1,000,000 years from now the land we known as Guyana will be over taken by foliage, rainforest and grass land; unrecognizable in comparison to Guyana today. In 1,000,000 Mount Roraima, Pakaramia Mountains, Mount Ayanganna and the Kanuku Mountains will be covered in moss and rainforest.

the unspoiled Rainforest in central Guyana

Beyond the ever going changes of earths surfaces the Land of Many Water know as Guyana will be completely altered and unrecognizable 1,000, 10,000, and 1,00,00 years from now.
