The untold story of an iconic river, from its origins to its possible futures on a rapidly warming planet

The Nile River has captivated explorers and scientists for centuries, and its age and origins have been the subject of intense speculation since at least the days of Herodotus. The Nile Revealed is an authoritative account of how Earth's longest river came into being, how its flow has changed dramatically and at times almost ceased altogether, and how these changes affected human societies in the Nile valley down through the centuries.

An internationally renowned expert on the Nile and its extraordinarily rich geological history, Martin Williams has traveled the length and breadth of the river during his career. In this book, he draws on his own experiences to explain how scientists reconstruct and date past environments in the Nile basin and offers vivid descriptions of the river and its three major tributaries—the White Nile, the Blue Nile, and the Atbara. He guides readers from the Ethiopian Highlands and downstream to the Nile delta and deep-sea fan, where soils and sediments preserve the record of the Nile's eventful life. Williams visits prehistoric sites in the Nile valley and considers how its inhabitants adapted to floods, droughts, and other climatic changes—and how the river itself might respond to climate change in the future.

Blending evocative storytelling with the latest science, The Nile Revealed provides an incomparable look at a majestic river whose course has fluctuated widely over time, and whose waters have sustained diverse ecosystems and humankind for millions of years.
