Automating an #OpenSource approach to Flood Analysis - adapted guide from Hans van der Kwast 🏞️ Southwell has a long history of flooding, with major events causing significant damage to homes, businesses, and infrastructure. One of the most severe occurred in June 2007, when heavy rainfall led to the River Greet overspilling, inundating large areas of the village. Since then, Southwell has remained vulnerable, with ongoing efforts to improve flood resilience, evacuation planning, and mitigation strategies. A few years ago, during my time at Nottingham Trent University I was part of the Southwell Flood Forum, working alongside Chloe Bottomley, council members and residents to understand clear evacuation routes and identify roads at high risk of flooding, and ways to improve safety and ensure coordination. These discussions were essential in developing local strategies to enhance safety and preparedness for future flood events. Southwell Live River Information : https://lnkd.in/ejKRRQbc Southwell Flood Forum : https://lnkd.in/eamjTKNw The maps below are an adaptation of the flooding analysis course developed by Hans van der Kwast. Using #QGIS model builder, I have automated all the steps outlined in the guide, creating a streamlined workflow that can be applied to different regions, with just an AOI and Elevation data. Using QGIS, we can strategise for safety, supporting communities in mitigating flood risks and improving disaster resilience. Organisations like FPS Environmental Ltd and The National Flood Forum play a crucial role in raising awareness and helping homeowners make their properties more flood-resilient, and with GIS, we can provide data-driven insights to enhance flood prevention, optimise mitigation strategies, and support emergency response planning more effectively. QGIS applied for flood emergency enables key descision makers to visualise: ✅ Heavy rainfall accumulation & runoff patterns ✅ Areas most susceptible to flooding ✅ Potential damage to homes & infrastructure ✅ Blocked & alternative evacuation routes If you're interested in a copy of my automated flood analysis model, feel free to message me, it's a work in progress but a good starting point. 🌍 Amazing guide by Hans van der Kwast : https://lnkd.in/eAFstWzJ #GIS #FloodRisk #QGIS #DisasterResponse #Southwell #FloodAnalysis #GeospatialSolutions #ClimateResilience #MappingForGood
