Types of spits

A spit -refers to a low, narrow ridge of sand or shingle joined/ attached to the mainland at one end with the other end extending in the sea.




a spit develops where the river deposit large quantities of materials into an estuary and then long shore drift moves the materials to form a linear shape with one end joined to the mainland with the other extending in the sea or lake

Spits exist at Kaiso and Tonya on Lake Albert, and Ras Luale north of Dar es Salaam.

A spit May link the two headlands to form a bay bar.

Types of spits

Hooked spit /curve spit – this is a narrow embankment of sand or shingle attached to land one end with the other end extending to the sea being curved across a bay or an estuary by the longshore drift.




The hooked spit is formed when waves moving obliquely to the shore/ longshore drift tends to swing around the end of the spit extending to the sea and curves it toward the shore, or waves approaching the shore from several directions

For example Kaiso on the Eastern shore of Lake Albert and Ras Luale near Dar es Salaam.

Cuspate spit- this is applied to two spits converging off shore or when longshore drift recurves the hooked spit until it becomes attached/ joined to the shore at both ends.

For example Tonya point on Lake Albert
