This paper applies the principles of water-use accounts, developed in the first of the
series, to the São Francisco basin in South America. The São Francisco Basin lies wholly
within Brazil. There are several major dams and wetlands in the Basin.
Net runoff is about 16% of total precipitation. Grassland is the most extensive land use,
