Biogeochemical Classification of South Florida’s Estuarine and Coastal Waters of Tropical Seagrasses

South Florida’s watersheds have endured a century of urban and agricultural development and disruption of their hydrology. Spatial characterization of South Florida’s estuarine and coastal waters is important to Everglades’ restoration programs. We applied Factor Analysis and Hierarchical Clustering of water quality data in tandem to characterize and spatially subdivide South Florida’s coastal and estuarine waters. Segmentation rendered forty-four biogeochemically distinct water bodies whose spatial distribution is closely linked to geomorphology, circulation, benthic community pattern, and to water management. This segmentation has been adopted with minor changes by federal and state environmental agencies to derive numeric nutrient criteria.

Parallel relationships, architecture and water : the urban spa

This thesis explores the relationship of architecture and water through the design of an urban spa that offers both a bodily and a poetic experience of water. Research included investigation of recent architectural projects that enhance and order the view, sound, and touch of water as well as projects that integrate fountains, showers and reflecting pools into the experience of a building. In the design of the spa, the movement of water was based metaphorically on the natural water cycle: evaporation, condensation and collection of water in pools. The building presents fountains, rivulets, and pools in a descending sequence that represents the natural flow of water. The temperature of water and the activities of the spa follow the same descending sequence, progressing from a warm water bath at the top of the building to cool swimming pool at the plaza level in a contemporary interpretation of the experience of a Roman Bath.
