Kinetic roughening of the urban skyline
journal contribution
posted on 2020-05-29, 11:01 authored by Sara Najem, Alaa Krayem, Tapio Ala-NissilaTapio Ala-Nissila, Martin GrantWe analyze the morphology of the modern urban skyline in terms of its roughness properties. This is facilitated
by a database of 107 building heights in cities throughout the Netherlands which allows us to compute the
asymptotic height difference correlation function in each city. We find that in cities for which the height
correlations display power-law scaling as a function of distance between the buildings, the corresponding
roughness exponents are commensurate to the Edwards-Wilkinson and Kardar-Parisi-Zhang equations for kinetic
roughening. Based on analogy to discrete deposition models, we argue that these two limiting classes emerge
because of possible height restriction rules for buildings in some cities.
