Way Beyond Bigness is a design-research project that studies the Mekong, Mississippi and Rhine river basins, with particular focus on multi-scaled, water-based infrastructural transformation. The book proposes a simple, adaptive framework that utilizes a three-part, integrative design-research methodology, structured as: Appreciate + Analyze, Speculate + Synthesize, and Collaborate + Catalyze. To do such, Way Beyond Bigness realigns watersheds and architecture across multiple scales (sites to river basins), disciplines (ecologists to economists), narratives (hyperboles to pragmatics), and venues (academics to professionals), defined as Watershed Architecture.
