Urban flooding hazards are complicated by the heterogeneity of cities—various types of land use, development, surfaces, and drainage systems can all change how water moves. Flooding can be localized to areas as specific as a block or a street corner and change quickly, making it difficult to monitor hyperlocal floods distributed across a city in real time. Crowdsourced flood reports from citizens (such as social media posts) are helpful during such events, but the coverage and accuracy can be spotty given that they require human witnesses to register events.

The flood of 1953, while a tragedy, serves as a poignant reminder of the ongoing threat posed by rising sea levels and the importance of proactive preparation, especially due to much of Canvey Island sitting below the daily high-water level in the Thames Estuary. It inspires continued efforts to address climate change and design accordingly. 'MicroSuDS' is a finer approach to stormwater management and is gaining traction, Including innovative solutions from GreenBlue Urban including the Hydroplanter Flex which was installed here at Canvey Island. The Station Approach scheme was developed by Morgan Brookes, where flood issues were addressed and approved by Castle Point Borough Council. Consideration of local flood risks, like those on Canvey Island is crucial. Resources like the https://lnkd.in/g9C5zY4t flooding service provides valuable insights for proactive mitigation. Together, with innovative SuDS solutions and strategic planning, we can create resilient and sustainable urban environments. #SuDS #CanveyIsland #CaseStudy #BeforeAndAfter #WoWWednesday https://lnkd.in/gmQ87FJ7

"Coproduction is essential across all components of the research agenda to ensure, for example, that improved flood exposure data empower marginalized communities. Better flood data will assist efforts to create fair flood metrics and to discourage risky urbanization. And uprooting current urban development practices through science-informed policy measures could help reduce downstream effects of flooding that often span borders." #geospatial #floodinjustice #floodrisk

Researchers with Louisiana State University’s College of the Coast & Environment have developed a new tool aimed at helping Baton Rouge city planners boost flood resilience while also tackling blight. #flooding #environment #batonrouge #louisiana

If your role is connected with flooding, flood resilience or natural flood management in the Calder Valley or you live in Calderdale and have experience of flooding please help us test an online map-based tool. You have still time to help us by completing the survey before the end of November - and it would be great if you could share amongst others https://lnkd.in/eDJ3K2qk The tool has been developed as part of a West Yorkshire Flood Innovation Programme (WYFLIP) within an Accelerator project, which focuses on developing collaborative approaches to collecting local knowledge and experience on flooding in the Calder Valley. Originally developed by University of Leeds, it uses a Google Map base with a spray can tool that allows users to spray ‘paint’ on the map to highlight things like which locations in the Calder catchment flood most frequently. We want to improve our knowledge of public perceptions of flooding and the links between land use, management and climate change in the catchment with the ultimate aim of reducing flood-related impacts in the future. It can be used to identify:- which places flood frequently and suffer the deepest flooding how often this happens and what is the impact of the flooding how climate change will affect future flooding which areas upstream are causing the flooding within the valley and what interventions might reduce this in future. All spray patterns and the responses will be analysed to build up a broad picture of what stakeholders think and understand about flooding in the valley. The data will be analysed to look for common patterns and will be used to inform future flood management in the Calder Valley. #flooding #floodresilience #research #survey Andy Bray Katie Kimber Amanda McDermott Samuel T.

“The whole purpose of this paper is to provide data to support decisions. Every city, every county has a flood resiliency plan in place. They are required by law to create that. But it’s likely nobody has received the entire picture until this study, which creates probably the first comprehensive picture of what’s happen in the not-too-distant future.”- Manoochehr Shirzaei, Director of Virginia Tech’s Earth Observation and Innovation Lab on the short term picture of coastal flooding risks. In this article, learn about the work of Shirzaei and his research team who have built some of the world's first high-resolution depictions of the sinking land along U.S. coastline. The recent study provides a new comprehensive look at the flood risks for 32 cities on three coasts by 2050.▶ https://lnkd.in/eVhekMRQ More information on the Earth Observation and Innovation Lab here : https://lnkd.in/e9R-qjB5 #coastalresilience #coastalprotection #flooding #virginiatech

Imagine having a "Manning Equation" for urban flooding - one grounded in fluid mechanics and the statistical properties of a city's urban layout. Well, we've got one now - thanks to great work by Sarah Balaian and Mohammad Javad Abdolhosseini Qomi and support from UCI Flood Lab. Given an estimate of the overland flow rate (m^3/s/m) crossing a city, you can estimate the average flood depth and velocity. UC Irvine Civil & Environmental Engineering

I am excited to share our new paper evaluating the quality of networks of plans to advance flood resilience, with my coauthors Sierra C Woodruff, Sara Meerow, Bryce Hannibal, Melina Matos, Ph.D., and Philip Gilbertson! ---- Urban flood resilience is a function of the collective intent of all planning efforts or network of plans. Yet, most studies focus on single plan types; it is unclear whether plans work cohesively. We asked to what extent do networks of plans uniformly foster resilience to flooding. We adapted plan quality evaluation methodology to evaluate four cities’ networks of plans. All four networks uniformly state goals, including flood resilience and sustainability goals, but exclude details on flood exposure and vulnerability. Moreover, all four networks lack implementation guidelines. We identify opportunities for more integrated planning to tackle flooding and climate change. https://lnkd.in/gSyn5rzw

Recent study on the climate impact in Oklahoma's tribal nations revealed alarming projections. Heavy rainfall, two-year floods, and flash floods are set to escalate, posing heightened risks. Particularly concerning is the forecast of heavy rainfall in Indigenous communities surging by over 500%.Learn more about it here! #ClimateChange #TribalNations #Oklahoma #ClimateImpact #Flood #Explore #Floodinsurance #Insurance

Mangroves save $855b in Global Flood Mitigation Costs – University of California The study highlights the importance of mangroves in protecting coastal communities from floods, storm surges and erosion, offering significant environmental and economic benefits. “As climate change accelerates the frequency and severity of storms, the need for effective coastal defences has become increasingly urgent,” University of California, Santa Cruz says in its news release. https://lnkd.in/g_nF2stR #Coastal #CoastalNews #CoastalProtection
