Recent and Historic Drivers of Landscape Change in the Everglades Ridge, Slough, and Tree Island Mosaic

More than half of the original Everglades extent formed a patterned peat mosaic of elevated ridges, lower and more open sloughs, and tree islands aligned parallel to the dominant flow direction. This ecologically important landscape structure remained in a dynamic equilibrium for millennia prior to rapid degradation over the past century in response to human manipulation of the hydrologic system. Restoration of the patterned landscape structure is one of the primary objectives of the Everglades restoration effort. Recent research has revealed that three main drivers regulated feedbacks that initiated and maintained landscape structure: the spatial and temporal distribution of surface water depths, surface and subsurface flow, and phosphorus supply. Causes of recent degradation include but are not limited to perturbations to these historically important controls; shifts in mineral and sulfate supply may have also contributed to degradation. Restoring predrainage hydrologic conditions will likely preserve remaining landscape pattern structure, provided a sufficient supply of surface water with low nutrient and low total dissolved solids content exists to maintain a rainfall-driven water chemistry. However, because of hysteresis in landscape evolution trajectories, restoration of areas with a fully degraded landscape could require additional human intervention.

Campus Design: Locating a new center of international studies

FIU's campus master plan should portray an overall concept of the University's vision. Its design should represent a distinctive sense of institutional purpose. Its architecture should support the campus design in the realization of an ideal academic environment. The present master plan of Florida International University (FIU) offers neither a clear typology of architectural elements nor adequate relationships and connections between buildings. FIU needs to enhance its master plan with an architectural and urban vocabulary that creates a better environment. This thesis will examine FIU's present master plan, explaining the history of its development. Further, it will critically examine the quality of the campus, highlighting the success and failure of its various parts. The unrealized potential of the campus' original vision will be juxtaposed to the built reality. In addition, FlU's planning strategies will be parallel with the planning of several master plans of American universities. Finally, this thesis will propose a set of criteria for the inclusion of a new building in the campus master plan. The Center of International Study will be the catalyst that would bring into focus the university's vision. As a means to prove the validity of these criteria, a new location for the center of international studies will be selected, and a schematic architectural proposal will be made.
