Abstract
Urban flooding is a major problem in cities around the world, including Lahore, Pakistan. The
city is increasingly at risk of flooding due to heavy rainfall and poor management practices.
This research explores rainwater harvesting (RWH) & bioswales as a possible sustainable
solution to this problem, using geographic information systems (GIS) and remote sensing
techniques for in-depth research. We use the Analytic Hierarchy Process (AHP) to examine
various factors including land use/cover, slope, rainfall and drainage patterns to assess flood
risk at different geographical scales, including union councils. The study identifies flood-prone
areas, proposes RWH techniques, and evaluates the effectiveness of each strategy in reducing
urban flooding. The results highlight the importance of integrating nature-based methodologies
for sustainable urban development and contribute to flood management strategies and
sustainable water solutions.
