The Busan River Museum, a learning environment about the river itself, sits at the edge of a tidal flow and becomes part of it. The building’s own formation is imagined in the same way a river delta is formed. Sharing the same forces of erosion and buildup of the river delta, a process called “cracking” forms the building like its surroundings.
The cracking procedure is fractal by nature and allows for both an organization of program and a distribution of tidal movements that together make the building behave like a mouth of a river. Its waterways and triangular deposits are places for the museum program to inhabit and partake in the river ecology.
