Abstract

PEREZ, Jhonny I.; NARDINI, Andrea  and  ZUNIGA, Yesenia P.. Identification Multiattribute of Typologies of Flood-Vulnerable Housing in Riohacha, La Guajira- Colombia. Inf. tecnol. [online]. 2018, vol.29, n.5, pp.187-202. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642018000500187.

The most representative house typologies in the city of Riohacha-Colombia have been identified with the aim of analyzing the effects of urban floods. The Multiple Correspondence Analysis (MCA) technique was applied to the data previously obtained through questionnaires to 411 households in the area affected by floods in the winter season 2010-2011. Four possibilities were explored between the selection of the attributes to be considered and different options for their measurement in qualitative and quantitative scales. The ACM3 which grouped the dwellings into 13 typologies was selected. From these, the five most representative ones were selected, including the most vulnerable dwellings (one-floor dwellings with wattle and daub walls). The ACM proved to be a suitable tool, because it is sufficiently versatile and manageable, although it requires a zoom to the perceptual map when the analysis is conducted with numerous cases.

Keywords : typology of housing; vulnerability; urban floods; multiple correspondence analysis; MCA.
