crisis_mapping_flood icon crisis_mapping_flood

This code provides methodology for preparing flood hazard maps in a replicable way, particularly for the coastal cities where floods pose a recurrent danger because of climate change and its impact on sea level rise. Taking San Francisco, California as an example and using OpenStreetMap data from OSMnx Python Package, our study compiled a crisis map indicating hazard prone areas for evacuation management or emergency access.

Floods are the most destructive form of natural hazards in both local and global context. This is true in terms of both loss of life and property damage. Early flood forecasting can be used to identify potential areas of flooding in order to develop mitigatory planning and evacuation programs to remove people from such areas during flooding and also to implement suitable preventive measures to avoid damage to properties. In this project, our main objective is to build a flood forecasting system for Mi Oya river basin(Sri Lanka). Mi Oya Basin is heavily affected by seasonal flooding and droughts. As per the available data, floods in the Mi Oya basin are unleashed due to river overflow and reservoir spilling. Out of the several reservoirs located in the basin, Tabbowa and Inginimitiya are crucial in worsening the flood impacts as these two reservoirs are frequently spilling under adverse weather conditions. As such, the prevalence of a real-time flood forecasting model with the incorporation of the reservoir operations for the entire basin is essential to alleviate the flood induced impacts while preserving the optimum volume of water in the major reservoirs in the basin.

Flood Mapping Python Toolbox: The FLOod Mapping PYthon toolbox is a free and open-source python toolbox for mapping of floodwater. It exploits the dense Sentinel-1 GRD intensity time series and is based on four processing steps. In the first step, a selection of Sentinel-1 images related to pre-flood (baseline) state and flood state is performed. In the second step, the preprocessing of the selected images is performed in order to create a co-registered stack with all the pre-flood and flood images. In the third step, a statistical temporal analysis is performed and a t-score map that represents the changes due to flood event is calculated. Finally, in the fourth step, a multi-scale iterative thresholding algorithm based on t-score map is performed to extract the final flood map. We believe that the end-user community can benefit by exploiting the FLOMPY's floodwater maps.
