Climate change has been a rising issue with a persisting global warming. In Glassgow 2021, Cop26 has aimed at 1.5° within reach through adaptation, mitigation, finance and collaboration. Global sea-level rise (GSLR) endangers coastal cities with the increase of 0.3 m in sea level annually in different regions. In the realm of adaptation, a pragmatic intervention and smart nature-based solutions (NBS) is to adapt to change. Studying Coastal regions contours and simulating a GSLR can track channels to adapt to this change and benefit it to support blue infrastructure (BI). Green life sustains natural ecosystems in-tangent with built environment which requires BI to maintain its livability. Branching water through channels to artificial lake is a NBS to react to GSLR instead of resisting it. GIS analytical tools and 3D simulation platform traces low-elevation coastal zones to adopt this strategy. BI branching is a parametric solution by replacing water spread on surface while endangering on-land life with orienting the increase in water to artificial blue features through water streams. This strategy promotes aquatic ecosystem life and expand it to remote areas while enriching urban comfort. Change is the notion on which life on earth evolutes or else we will still be living in the dinosaurs’ era. Eventually, an adaptive geographic metamorphosis occurs to adapt rather than resist change through BI Transfiguration.
