Digital dunes

parameterizing coastal bioscaffolds through Jundu Growth Logic

Abstract

Facing the climate emergency and accelerating coastal erosion, traditional rigid engineering solutions have proven insufficient and ecologically disconnected. This article proposes a regenerative design approach that unites digital morphogenesis with the ecological wisdom of native species, aligning with the theme "sowing futures." The work presents the development of coastal "bio-scaffolds"—artificial dunes designed not only as physical barriers but as bioreceptive infrastructures intended for colonization by Jundu (psammophilous vegetation). The methodology employs L-System algorithms to simulate the growth and rooting logic of this vegetation, translating biological parameters of propagation and sand fixation into computational geometry. The result is digitally fabricated porous prototypes, whose morphology has been optimized to capture sediment and offer protective niches for the establishment of native flora. By hybridizing parametric design with natural processes, the study demonstrates how design can act as an agent of landscape healing, transforming technical infrastructure into a regenerative experience of coastal daily life.
