Flood-Resilient Infrastructure Design Using GIS and Remote Sensing in Pakistan

Abstract

Pakistan is very susceptible to floods due to its geographical position, the monsoon variability and the poor planning of urban development. Flood events not only result in huge losses to people and their economy, but also destruction of critical infrastructures. Design of flood-resistant infrastructure is critical in order to reduce these impacts. Geographic Information System (GIS) and Remote Sensing (RS) can be used to give an edge-to-edge tool for mapping flood risk, hazard risk analysis, and resilient infrastructure planning. This study discusses the use of GIS and RS in the design of flood-resilient infrastructure in Pakistan as it includes the methodologies, challenges, and benefits of the methodologies. The studies highlighted the importance of spatial analysis, hydrological modelling, and satellite images to aid infrastructure plans in order to mitigate flood risks, improve disaster planning and adaptive resilience to such issues and sustainable urban development. Findings fall that combining GIS and RS as part of the national and local planning frameworks can facilitate better decision-maki
