Vaal River
The Vaal River (/ ˈ v ɑː l / Afrikaans pronunciation:; Khoemana: ǀHaiǃarib) is the largest tributary of the Orange River in South Africa.The river has its source near Breyten in Mpumalanga province, east of Johannesburg and about 30 kilometres (19 mi) north of Ermelo and only about 240 kilometres (150 mi) from the Indian Ocean. It then flows westwards to its confluence with the Orange ...

Vaal River, northern tributary of the Orange River, South Africa.Rising at Sterkfontein Beacon near Breyten, in Mpumalanga province, it flows 750 miles (1,210 km) southwest to its confluence with the Orange near Douglas; the Vaal's middle section forms most of the Free State's northern provincial boundary. It is basically a plateau river and occupies a shallow bed.
Impact of Human activities on the Waterval River located in the Vaal
Rand Water's chemical water quality data from 1991 to 2000 were used to assess the water quality of the Waterval River, which contributes about 111 x 106m3 of water to the Vaal River annually.

Effects of human activities on the Waterval River, Vaal River catchment
Abstract. Rand Water's chemical water quality data from 1991 to 2000 were used to assess the water quality of the Waterval River, which contributes about 111 x 10 6 m 3 of water to the Vaal River annually. Due to a biological community's ability to reflect water quality changes over time, biomonitoring was undertaken to support chemical water quality monitoring.
