Remote Sensing Seminar of Tartu Observatory (30. May 2024). Piash Chowdhury made a presentation "Flash food potential risk zonation mapping using GIS‑based spatial multi‑index model: a case study of Sunamganj District, Bangladesh"
Summary:
The presentation on the potential risk zonation of flash floods in the Sunamganj District of Bangladesh, utilizing a GIS-based spatial multi-index model. The study integrates various indicators under four major indexes—Hazard, Exposure, Sensitivity, and Resilience—to develop a comprehensive flash flood risk map. Key aspects include the assessment of flash flood risks due to excessive rainfall, the comparative analysis of different indicators, and the examination of socioeconomic parameters to observe community resilience. I will also discuss the geostatistical methods and Principal Component Analysis (PCA) used in the data analysis, as well as the creation of risk zonation maps. This research aims to provide valuable insights for policymakers and contribute to more effective flood management strategies in the region.
