Thesis (MScEng)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: Since the construction of the causeway and the jetty during the early 1970’s in Saldanha Bay, various alterations to the coastline in the area of the Langebaan Lagoon mouth were observed. These alterations include the erosion of Langebaan Beach located near the town of Langebaan. An investigation was undertaken to identify the possible impact these structures had on the hydrodynamics and sediment transport of the Saldanha Bay and Langebaan Lagoon systems, focusing on the entrance to the Langebaan Lagoon.

A Combined Cycle Gas Turbine (CCGT) power plant is proposed to add 2370 MW of capacity to the national grid. The “new-build” CCGT plant will use natural gas as a feedstock for energy generation. The plant is destined to begin energy generation by 2019, and

Abstract:

The St Francis Bay beach has experienced chronic erosion over the past three decades. This erosion can largely be attributed to the stabilisation of a large coastal dunefield which contributed +/- 80 percent of the sand supply to St Francis Bay. Stabilisation began in 1975 initially using plant cuttings and followed by the development of the Santareme holiday suburb resulting in complete stabilisation by 1985. Effects were felt from the late 1970‟s and since then the beach has retreated at between 0.5 - 3 m.yr-1. Erosion has encroached on beachfront properties since the early 1990‟s, leading t

Abstract:

For suspended cultivation of seaweeds in the open ocean, the selection of suitable sites and the optimization of cultivation methods for maximum productivity are of utmost importance. Growth of raft-cultivated Gracilaria gracilis in Saldanha Bay is known to be badly affected in late summer due to the persistence of warm oligotrophic water at the ocean surface which prevents replenishment of nutrients by upwelling. This study documents the extent of nitrogen starvation during this period and investigates some possible methods of managing this problem. Nitrogen content, C:N ratio and stable isot
