SPOEG RIVER ESTUARY: Catchment Characteristics |

|
|
Main Rivers and tributaries | ||||
|
|
The main river entering the Spoeg River Estuary is the Spoeg River. The main tributaries to the Spoeg River are the Kraai and the Horees Rivers (Ref. 1). | ||||

Geomorphology | ||||
|
The coastal zone consists mostly of sandy
soils that support sparse strandveld vegetation that has adapted to
severe temperatures and limited moisture, but is extremely sensitive to
disturbance (Ref. 5). |
||||
|
Geology | ||||
|
The geology of the riverbed and inland catchment area is predominated by granites of the Namaqualand-Natal metamorphic complex. Along the coast, these bedrock granites are overlain by unconsolidated sands, with fluvial and terrestrial gravels, shells, limestone and calcrete cappings. (Ref.1.) | ||||
|
The Spoeg River, as is the case with other Namaqualand rivers, has been incised into granite bedrock and can be seen as a small water-course running down a wide shallow valley. The valley is filled with alluvium and rounded granite boulders. Granite outcrops can be seen in places in the valley and also along virtually the whole of the adjacent coastline (Ref. 1). | ||||
