    Temporal Urban Growth Analysis and Potential Site Identification for A High Rising Buildings in Bahir Dar City
    (2009-12) Mebratu, Haimanot
    The Urbanization level and the land use dynamics of Bahir Dar is assessed in the field of GIS and Remote sensing technology for excellent understanding of the emerging growth pattern using multi temporal dataset. And the results from a study about growth trends of the urban areas in Bahir Dar are described here. The period under consideration is from 1957 to 2005. It should be noted that the internal urban growth is evaluated in a separate manner and in the pre 1957 urban centers of Bahir Dar during 1957- 2005 built up area increases from 13 hectares to 33.68 hectares. In the 1957-1984 expansion areas during 1984-2005 built up area increases from 166 hectares to 210 hectares. In the post 1984 expansion areas 363 hectares of land is used for built up. With regard to the external growth of Bahir Dar two distinctive phenomena is visible from 1957 to 1984 the city expand ten times to its size of 1957 and from 1984 to 2005 again a three times growth from its size of 1984 is observed. In addition to the above urban growth analysis a suitability model for identifying potential developable land for high rising buildings has been carried out. This analysis is based on the physical and social parameters, besides in the present research all the empirical observations, the RS imagery and the GIS analysis have been used. This has been done in an integrated conceptual and operational frame work which adds an indicative bottom up perspective to the understanding of urban growth pattern
