Why Are Many African Rivers Unsuitable for Transportation?
- Waterfalls & Rapids: e.g., Victoria Falls on Zambezi blocks navigation.
- Seasonal Flow Variability: Dry season shallows; wet season flooding.
- Heavy Sediment Loads: Sandbars, shifting channels.
- Political Instability: Conflict hinders infrastructure investment.
- Lack of Infrastructure: Few ports, docks, warehouses.
- Economic Disadvantage: Often costlier than road/rail.
- Disease Vectors: Malaria, yellow fever along river corridors.
