Flood data, analysis, and results - oh my! Check out this new blog post highlighting three flooding workflows using ArcGIS Pro 3.3 - Arc Hydro, the Flood Impact Analysis solution, and Flood simulation - and how they work together. #esri #arcgissolutions #archydro #flooding #3Dsimulation #publicsafety #localgovernment

Revolutionizing Flood Forecasting with Artificial Intelligence Floods are recognized as some of the most frequent and devastating natural disasters, particularly in developing countries where dense streamflow gauge networks are often unavailable. The need for timely and accurate flood warnings is widely acknowledged as critical for reducing risks and saving lives. Through the use of artificial intelligence, significant advancements have been made in flood forecasting. AI-based models have been shown to predict extreme riverine events in ungauged watersheds with up to a five-day lead time, offering accuracy that matches—or even surpasses—nowcasts from the current state-of-the-art system (Copernicus Emergency Management Service - Global Flood Awareness System). Accuracy levels for major events (five-year return periods) are achieved at rates comparable to smaller-scale events (one-year return periods), allowing larger and more impactful floods to be forecasted earlier and more reliably. These models have already been incorporated into an operational early warning system, through which free, real-time flood forecasts are being provided to over 80 countries. The importance of improving access to hydrological data globally has been emphasized to further enhance the reliability of flood warnings and strengthen disaster preparedness. A safer and more resilient future is being built, with lives and communities protected through these efforts. 🌍

Effective flood response with ICEYE Flood Insights in New Zealand In the event of a major cyclone or flood anywhere in New Zealand, ICEYE’s near real-time hazard analytics, including Flood Insights for observation-derived flood depth and extent, is available for the Esri ArcGIS platform. The partnership between ICEYE and Eagle Technology enables Flood Insights in ArcGIS Online to transform the approach to emergency management operations and positively impact all New Zealanders during the response efforts.

Today saw the release of the latest NaFRA flood mapping for England. It is the first time the surface water maps from the NaFRA has considered the latest UK climate projections from the Met Office, vital for assessing future risk. https://lnkd.in/eEJdRpvE This mapping has been updated using revised climate change predictions as well as updates to the underlying ground models. I was sat in a client meeting this morning to discuss a number of sites as the new mapping was released. It was interesting to see how the mapping has changed on each site and how we are looking at approaching the changes in light of the new NPPF and impending PPG. The latest mapping is available from the following link https://lnkd.in/efqTs2ym The new NaFRA mapping, can have a significant impact on planning applications and redevelopment layouts. Essentially, it provides updated information on flood risk areas, which is crucial for designing resilient and safe development projects.......and assessing if the dreaded Sequential Test is required! RSK LDE (Land and Development Engineering) are well positioned to consider these changes and have in house expertise to review and challenge the mapping through detailed 2d overland modelling, should site specific information become available (such as the inclusion of culverts under roads, or very recent changes in ground levels). Also…stand by for further updates to the Flood Map for Planning which is due to be released on the 25th March 2025 and any revisions to the PPG, which are due in the coming weeks

Thoughts from our Director of Hydrology Colin Whittingham on the updated NaFRA Flood Mapping for England. If you need any advice on Flood Risk, Flood Modelling, etc then drop Colin or our team of experts a line. We have Hydrologists based all across the country to provide local expertise. #floodrisk #FRA #Hydrology

🎉 Happy to share that our paper on stochastic coastal flood risk modelling for the east coast of Africa has been published! 🌀🌊 In our study, we developed a novel modelling framework for high-resolution continental-scale risk analysis. Using 10,000 years of synthetic tropical cyclone events and a cascade of hydrodynamic models, we simulated water levels, coastal flooding and damages for each event along the east coast of Africa to derive coastal flood risk. Using this modelling approach we obtained risk information usually not found on traditional large-scale flood risk assessments. We believe that this study represents a step forward in achieving large-scale flood risk assessments that account for the spatiotemporal dynamics of flooding events. Thanks a lot to my co-authors - Jeroen Aerts, Dirk Eilander, Philip Ward, Sanne Muis - for their great help and contributions to this research!

Flooding is becoming an increasingly serious issue, especially in light of Kosovo's challenges. Rapid and uncontrolled urbanization significantly raises flood risks, alters local hydrological conditions, and increases vulnerability. I'm excited to share that my co-authors and I have contributed to addressing this pressing issue through our paper titled “Understanding Flood in Kosovo: Spatial Patterns, Urban Influences, and Implications for Resilience in Lumbardhi i Pejës and Klina Catchments,” published in the International Journal of Disaster Risk Reduction (Elsevier). https://lnkd.in/d9_rYJkZ Our study aims to raise awareness and deepen our understanding of our flood risks: Intensive and uncontrolled urbanization is one of the most challenging problems related to future flood probabilities due to changes in local hydrological conditions and increased vulnerability. This study assessed the impact of unregulated urbanization on flood extent in two selected catchments, Lumbardhi i Pejës and Klina, in Kosovo. The results confirm uncontrolled urbanization has escalated peak discharge and expanded areas affected by flash floods and floodplains.

Accurate and timely mapping of flood extent is crucial for effective disaster response and management. However, existing methods often face challenges in integrating diverse data sources and leveraging advanced techniques for precise inundation mapping. We address this issue in our latest paper, just published in Advances in Space Research. #flood #floodmapping #machinelearning #riskassessment
