Size variation in the rock hyrax (Procavia capensis) and late Quaternary climatic change in South Africa
Archeological site ; Biogeography ; Climatic variation ; Grassland ; Habitat ; Mammal ; Palaeo-ecology ; Palaeoclimatology ; Precipitation ; Quaternary ; South Africa
The average adult size of the rock hyrax varies greatly across South Africa. Regression analysis suggests that mean hyrax size is more closely linked to precipitation than to temperature, probably because precipitation has a much greater impact
on preferred hyrax food plants. In conjunction with other indicators of past climate, hyrax size variation can be used to reconstruct precipitation history near deeply stratified South African late Quaternary sites, including Elands Bay Cave, Die Kelders Cave 1

Grandiose plans, but insignifiant outcomes : the development of colonial ports at Twofold Bay, New South Wales

The paper examines the period between 1820 and 1920 to explain why the ports of Twofold Bay-Boydtown and Eden never sustained their challenge to Sydney's economic hegemony. These small ports provide an interesting insight into the economic
marginalisation of localities by the process of colonisation. Twofold Bay is examined within Rimmer's spatial model of port development. Uneven port development is examined as the geographical expression of several colonisation processes.

Three boundary layer models are applied to a wind energy siting investigation in the Saldanha Bay area. The different models were then tested and results compared. Favourable results were obtained for further development of the models. - (AJC)

struggle waged by Namibians against South African occupation. The paper charts the history of Walvis Bay's colonization and the conflicting claims of sovereignty. The principal focus is he process of bilateral negotiation and changes to the status following
Discussion of the focus and concerns of critical geopolitical analysis, with reference to the contested enclave of Walvis Bay. The eventual reintegration of Walvis Bay into Namibia in 1994 represents the final episode in a long and bitter liberation

Ground-penetrating radar (GPR) data for the Savannah River Site (SRS) in the Upper Coastal Plain of South Carolina, combined with geological, archaeological, and ecological data place new constraints on the evolution of Carolina Bays. Extant SRS bay
morphology formed mainly during the Holocene and did not involve migration of bays across the landscape. The results are interpreted to develop a model of bay evolution subsequent to the formation of the initial depression.

The aim of this paper is to determine whether wave energy in Tasman Bay is sufficient to initiate clast transport along the gravel platforms. In this study, wind data form Nelson airport and measured wave data from Cable Bay and Mackay Bluff
are used in conjunction with 2 different mathematical models of clast transport. Values calculated from each of these models are compared with the present wind and wave environment of Tasman Bay. While the mathematical models can only provide approximations
because of differences in bathymetry and wave morphology, they will provide a calibrated scale of clast movement along eastern Tasman Bay.

River sediment supply, sedimentation and transport of the highly turbid sediment plume in Malindi Bay, Kenya
Bay ; Coastal current ; Coastal environment ; Kenya ; Land use ; Monsoon ; Sediment transport ; Turbidity ; Watershed
The current velocities, tidal elevation, salinity and suspended sediment concentrations (TSSC) were measured in stations located within Malindi Bay in the Northern region of the Kenya coast. It is established that Malindi Bay receives a high
terrigenous sediment load. The river freshwater supply into the bay is highly variable. Relatively low peak flows occurred in November during the North East Monsoon (NEM). The discharge of highly turbidity river water into the bay in April and May occurs
in a period of high intensity South East Monsoon (SEM) winds that generate strong north flowing current that transports the river sediment plume northward. The mechanism of advection of the sediment plume north or south of the estuary is mainly thought
to be due to the Ekman transport generated by the onshore monsoon winds. The high sediment discharge into Malindi Bay can be attributed to land use change in the Athi-Sabaki River Basin in addition to rapid population increase which has led to clearance

Upland and coastal sediment sources in a Chesapeake Bay estuary

New data from the South River, Maryland and reexamination of existing literature suggest that coastal erosion may be the dominant process driving sediment inputs along the lenght of many tributary estuaries of the Chesapeake. This paper addresses
those issues by developing a sediment budget for the upper South River and examining resource management implications of that budget.

Dynamics of deflation hollows in the Elands Bay area, Cape Province, South Africa
Observations of erosion and deposition patterns in deflation hollows in the Elands Bay area, show that they are being slowly deepened and elongated in a SSW-NNE direction as a result of sand movements generated by southerly winds. This is probably

Les AA. se demandent si les ambitieux projets sur la ville nouvelle de Richards Bay, suppléer le port de Burban et équilibrer l'armature urbaine provinciale, ont été réalisés. En rappelant l'historique de ces deux villes portuaires et en décrivant
leurs paysages contemporains, les AA. montrent à quel point les objectifs initiaux ont quelque peu été surestimés. Cependant Richards Bay, par ses atouts présents et surtout futurs doit être gratifiée d'un relatif succès.
