Human intervention of the landscape by damming, filling wetlands and over-extracting is resulting in the rapid perversion of water bodies through the desertification or flooding of terrain and the ensuing contamination of reservoirs. In turn, these changes are disrupting ecosystems, reshaping geological borders, and causing irreversible damage that poses a threat to clean water supplies. As humans exert agency over local hydrology, there is scarce consideration of the ensuing ecological consequences. This thesis aims to expose the ecological transformations of territories laced with human agency by examining the residues left by water in order to deviate from the misplaced nostalgia of a return to nature in favor of a critical awareness. Clay, a residue historically significant for its elasticity and widespread availability, becomes a registration of these transformations. Through the integration of traditional slip-casting and contemporary digital fabrication methods, the thesis attempts to reveal these changes through the form-making of a temporal ecological monument.
