Analysis Of Urban Flooding Due To Climate Change, During Monsoon In Islamabad And Rawalpindi

Abstract

Urban floods are counted as the most devastating natural hazards and the climate change impacts make this hazard more vulnerable, when it hits the densely populated cities of the developing countries, it damages the property and results many casualties. During monsoon season Islamabad and Rawalpindi receives unpredicted intense precipitation, which causes flooding in the low-lying areas of Rawalpindi along Nullah Lai, while Islamabad is the master planned city and affect less. Climate change impacts cause’s extreme precipitation events and unplanned infrastructure development occur due to rapid urbanization while completely altering the natural land structure. This research majorly emphasizes on the causes and effects of urban flooding and its impacts on the natural and built environment of Islamabad and Rawalpindi. Study included the qualitative content analysis of urban flooding and analyzed the extreme water events of Nullah Lai for the period of 2010 to 2020. The main purpose to conduct this research was to determine the causes and effects of increase in urban flooding, for this purpose 26 scientific piece of writings (19 scientific published journal articles, 4 websites and 3 reports) relevant to the specific concept of the research problem and research question were reviewed and analyzed. The study found the natural and anthropogenic factors as the main causes of increase in urban flooding, which suggests to install modern technology to predict intense natural weather patterns (precipitation) and must adapt sustainable and resilient infrastructure to control and mitigate future adverse impacts of urban floods in the rapidly urbanized areas.
