Model answer

(a) e.g. Niger – Kainji (Nigeria); Volta – Akosombo (Ghana); Zambezi – Kariba (Zambia/Zimbabwe) or Cabora Bassa (Mozambique); Nile – Aswan (Egypt) or Owen Falls (Uganda); Zaire – Inga
(b) Many large rivers with big volume; rivers falling over plateau edges with waterfalls and rapids; deep narrow gorges for dam sites; heavy rainfall in the catchments; shortage of coal and need for cheap power; large lakes possible on impermeable rock; growing demand from towns and industries
(c) Cheap power for industries (Valco smelter, copper refining) and homes; reduces use of firewood; irrigation and water supply from the reservoirs; fishing on the lakes; lake transport; flood control; export of electricity; tourism and employment
