Flood Plains Abstraction — Okavango Delta

An aerial view of the Okavango Delta’s seasonal flood front — the advancing water creating a dynamic boundary between dry Kalahari sand and flooded grassland.
Description
The Okavango Delta is the world’s largest inland delta — a river system that flows from the Angolan highlands to disappear into the Kalahari Desert, flooding a vast inland area each year. This aerial photograph, made from a research aircraft during the annual flood front progression in April, captures the dynamic leading edge of the flood — the precise boundary between dry khaki Kalahari grassland and the silver-blue advancing water sheet — from 400m altitude. The complexity of the flood front, with its fingers of water penetrating along channels and depressions in the landscape, creates a graphic boundary of extraordinary biological and visual significance.
