Each realm was its own little city with all four different types of land use within them. The urban realms model sought to address this weakness in the multiple nuclei model by proposing that instead of nuclei, cities possessed realms. Despite their expansive scale, there was evidently a high degree of interconnectedness and interdependence among the various zones, neighborhoods, and suburbs of the cities.The scale of these new American cities was unprecedented. ![]() The multiple nuclei model failed to account for two features: They are, essentially, self-contained cities.īy contrast, in the multiple nuclei model, each section of a city (or ‘nucleus’) doesn’t necessarily function as a city with all the commercial, residential, and industrial land types within them.Ī major drawback of the multiple nuclei model was that as American cities began to expand rapidly following the post-war boom years of the 1950s and 1960s, the multiple nuclei model could no longer explain the layout of urban agglomerations.
