Goukourivier [previously known as Kafferkuils (CSW24)] and Duiwenhoks (CSW23)

Abstract

In the Kafferkuils now known as the Goukourivier the sediment dynamics of the estuary mouth region have been altered by the breaking of the sediment pathway into the historic sediment sink east of the mouth. This is done by the initial fixing of the drift sand region by planting programme and the subsequent building of road and houses across the sand transport route. But little information exists on both Kafferkuils and Duiwenhoks estuaries. The sediment and hydraulic dynamics of both the systems have been investigated in some detail, but data on the biota and physico-chemical characteristics are sparse.
