Mamelodi is a multi-cultural township located 20kms east of the Tshwane city centre. It is a vibrant and complex place, alive with opportunity, diversity, talent and creativity. It is also however, afflicted by many problems, especially those of a social and economic nature, like unemployment, poverty, poor living conditions, and so on. Mamelodi therefore, is a place where the implementation of appropriate design could make a real difference in the lives of its inhabitants. The University of Pretoria Mamelodi campus, due to its prime location and inherent qualities, has the opportunity to contribute significantly to the upliftment and transformation of the people around it, and to become a place of value and pride. It is however, missing this opportunity for a number of reasons: the isolation and segregation of the campus, its anonymity and lack of local identity, as well as the inaccessibility of the campus to local residents. One possible solution would be the full integration of the campus into the surrounding community, thereby enabling the empowerment of people on both a physical and psychological level. Both of these types of empowerment can be achieved through modifications to the University boundaries and the reworking of the open buffer zone into an area of common ground – a transition zone where the University and the community can come together and be of value to one another. There are two levels of value – quantitative, which can be achieved through the implementation of a cultivated landscape, and qualitative, which is made possible through the creation of a maieutic landscape. In order to achieve a continuous, integrated urban fabric, this study primarily investigates the creation of a large-scale framework design that considers the site in its entirety. The organising element in this regard was the existing storm water system which was also regarded as a missed opportunity. The study then progresses to a more detailed level in an area which was deemed to possess challenging and diverse options. The space chosen is located at the entrance to the UP Mamelodi campus library, in the transition zone between University and community, where it functions as a public square. Both the principles of integration and maieusis were applied here in a bid to create an empowering landscape that is immersed in its context, that is accessible, and that is therefore used and appreciated by many. / Dissertation (ML(Prof))--University of Pretoria, 2008. / Architecture / unrestricted

Cette thèse a pour objectif d’étudier les aménagements hydrauliques de Termessos en Pisidie dont le site montagneux et isolé est dépourvu de sources, en rassemblant le corpus de toutes les structures explorables, et d’en définir l’intérêt technologique et socio-Historique durant l’époque hellénistique et impériale. Après le dépouillement des sources écrites et de la bibliographie moderne, nous avons effectué une exploration détaillée du terrain. Plusieurs méthodes ont été appliquées au cours des six prospections archéologiques qui ont eu lieu entre 2010 et 2013, telles qu’une étude géophysique par radar à pénétration du sol et une analyse par magnétomètre à vapeur (gradiomètre). Nous avons eu également recours à la collaboration interdisciplinaire avec des spécialistes architectes, géographes, géologues, hydrologues et archéologues. Dans le cadre d’une recherche comparative, de nombreux sites antiques ont été visités en Anatolie, en Grèce, en France et en Espagne afin de mieux appréhender l’évolution du système hydraulique dans différentes conditions géographiques. Suite à ces travaux, 162 structures hydrauliques ont été observées et inventoriées. Nous avons identifié deux nouveaux types de citernes antiques, un barrage bien conservé, un édifice de spectacle et l’unique sanctuaire dédié à Pan découvert en Anatolie jusqu’ici. Nous avons interprété les vestiges de deux constructions comme des établissements thermaux. Force est de constater que face à un milieu naturel hostile, les Termessiens ont romanisé leur ville en effectuant des travaux considérables, leur permettant de couvrir leurs besoins en eau et d’accéder au niveau de vie urbain de l’époque impériale romaine. / The aim of this PhD is not only to focus on Termessos' hydraulic settlement, which has been erected on a sourceless location, but also to examine all explorable structures in order to define their socio-Historical interest and highlight their value to the understanding of hellenistic and roman times. We have started by studying the written sources and by conducting extensive research on site. Different technics have been employed such as georadar technology (Ground Penetration Radar, GPR) and vapour magnetometer (gradiometer) in order to collect data during the six archaeological prospections which took place between 2010 and 2013. Researchers from various disciplines have brought their expertise to this work : architects, geographers, geologists, hydrologists and archaeologists. During this investigation, many ancient sites have been explored in Anatolia, Greece, France and Spain in order to understand the evolution of the hydraulic system with regard to geographical requirements. Followings this, 162 hydraulic structures have been studied and registered. The irrigation and water supply network as well as the sewerage system have been restored. We have discovered two new types of ancient tank, a well preserved water dam, an entertainment building and the only sanctuary dedicated to Pan found in Anatolia so far. The remains of two establishments have been interpreted as thermal baths. Most of all, and despite a challenging natural environment, the Termessians have romanized their city by carrying out great major construction projects allowing them to fulfill their water needs and to celebrate their power.
