Multiple Nuclei Model by Harris and Ullman

Harris and Ullman proposed Multiple Nuclei Model in their paper The Nature of Cities (1945) to explain the morphology of a city. They argued that the land use pattern is much more complex than the model given by Burgress, Hoyt & Davis. They observed that the land use pattern is neither in concentric zones or … Read more

The Sector Model of Urban Morphology

Homer Hoyt and M.R. Davis proposed the sector model of urban morphology in 1939. This model was based on observations from 64 cities in the USA. He modified the Concentric Zone Model by Burgess in combination with the impact of transport routes on urban morphology and came up with their own Wedge or Sector Model. … Read more
