•Most rivers are seasonal and therefore the water levels fluctuate making it difficult to sail.
•Some of the rivers contain huge rocks/boulders/rock outcrops on their courses that reduce the navigable distance.
•High siltation in the lower courses of some rivers makes their channels shallow to suffice river transportation
•Most rivers have short and shallow navigable stretches thus discouraging development of transport in them
•Some rivers flow in areas of low economic value/sparsely populated areas that have limited human activities.
•Presence of waterfalls and rapids along the courses of some of the rivers hinder development of river transport as they have increased velocity of river water/very steep.
