Wami

The Wami River is a river in Tanzania's Pwani Region. The Wami and its tributaries have their origins in the Morogoro Region's the Eastern Arc Mountains. The river then runs northeast through the Pwani Region, eventually emptying into the Indian Ocean west of Zanzibar Island.

The Wami has a catchment area of 43,946 km2. The watershed area encompasses four ecological zones. Coastal woods run the length of the Indian Ocean. Woodlands and periodically flooded grasses characterize the plains of the middle watershed further inland. The Rubeho, Ukakuru, Nguru, and Nguu mountains, which are part of the Eastern Arc range, border these plains to the northwest. The Eastern Arc Mountains receive more rainfall than the surrounding plains because they intercept moisture-laden breezes from the Indian Ocean. The rainy season lasts from November to May, with mist and light rain falling at higher elevations throughout the dry season. The windward eastern and southern sides of the mountains get more rainfall than the northern and western slopes. These rains help to keep alpine forests alive, as well as the Wami's tributary rivers and streams. The Eastern Arc woods have a significant role in both supporting and controlling river flow.
