Over the past centuries, the land-water interface has generated a whole range of complex and interrelated spatial conditions in the Fraser River Delta. Our team set out to develop a spatial vocabulary, or Delta Lexicon, to document both prototypical as well as unique coastal landscapes in the region. As a means to systematically explore and document water-related landscapes, we developed a long list of terms associated with geomorphology, flood control infrastructure, agricultural practices, and human settlement. This list including terms such as dike, ditch, (sea) dam, flood box, pump station, culvert, sluice, pier, slough, wharf, quay, sea wall, jetty, reservoir, stream, canal, riparian corridor, bog, floodplain, wetland, mudflat, tidal flat, banks, cliff, valley wall/bluff, river island, foreshore, lagoon, oxbow lake, cranberry bog, beach, dunes, logs booms, and more. From here, the team began to investigate where landscapes related to these terms could be found in the region, and how they could be best visualized and communicated.
Each condition, whether unique or prototypical, was modeled at a specific scale (either 1:100, 1:200, 1:500, or 1:1000). By using a simple material palette (paper, newspaper, wire, and chipboard in neutral tones) the models could be iterated quickly. The physical models were then supported with a section and keymap highlighting the location(s) where this landscape condition could be found. In total 70 spatial conditions were documented in this way. The Delta Lexicon continues to serve as an educational tool and visual vocabulary through which we can communicate the diversity of coastal landscapes in the region with a range of stakeholders. The incredible diversity of spatial and socio-ecological conditions also makes it clear that there is no ‘one size fits all’ solution to address the implications of SLR. Instead, a range of strategies and approaches will be needed to respond to site-specific challenges (social, ecological, political and spatial) when it comes to flood management.
