Zambezi the overflow of the Zambezi in the rainy season.

Zambezi Conservation project—which follows the Zambezi River and stretches across Angola, Botswana, Namibia, Zambia and Zimbabwe—has received a grant of €8 million from a German nongovernmental organisation.

The river currently passes through Ngonye Falls National Park, Mosi-oa-Tunya National Park, and Lower Zambezi National Park (in Zambia), and Zambezi National Park, Victoria Falls National Park, Matusadona National Park, Mana Pools National Park, and the Middle Zambezi Biosphere Reserve (in Zimbabwe).
