Urban Flooding: The role of urbanization & climate change
Inundaciones urbanas: El papel de la urbanización y el cambio climático
Keywords:However, the impact varies with the place, namely coastal, hilly and interior
Urbanization means un-planned growth of the city. Slum culture is the principal character of unplanned growth in urban areas, more particularly in capital cities of states. However, the proportion of such character varies significantly with city to city. Extremes in rainfall also vary with space and time in association with the rhythmic variation in rainfall, which is the principal component of climate change. River floods follow this natural rhythmic pattern in rainfall. Both these scenarios are aggravated multi-fold by human interference through the destruction of nature/hydrology. These impacts change with location of urban areas, namely coastal, hilly & inland. The wastewater generated in urban areas also follows the population but major share of this water is imported from far away sources [ex-situ] and taken from groundwater. As a result even with not much rain, urban floods became a regular phenomenon. These issues are discussed in brief in the article with few examples.
