    “Here is a clear and simple breakdown of some of the latest bombshell findings out of the UBC Hydrology Lab… using a probabilistic framework, known as attribution science in the climate world. [The researchers] studied two watersheds in BC's Okanagan Valley near Summerland. In this area, they found that climate change was actually making the frequency of floods go down, but forest harvesting counteracted the effects of climate change and increased the flood risk by 10-fold (!!!) turning a 20-year flood into a flood that occurs every two years. [The H/T] truly want to know how the BC government and timber industry are responding to this new science internally. They're absolutely silent on it in public as they continue business as usual…”

  2. #WaterburyCT receives $339K DEEP grant for #RisdonDam removal project

    By Dalton Zbierski, 7/4/2026

    "A vision in Waterbury is en route to becoming reality, as the city received a grant from the state this week to help kickstart the Risdon #DamRemoval Project on South Main Street.

    "The $339,000 Long Island Sound Ecosystems Grant from the Connecticut Department of Energy and Environmental Protection will fund an important early stage of the project to remove the aging Risdon Dam.

    "The grant will cover the environmental investigation, engineering design and permitting required for the removal of the dam, which is located behind the former factory at 2100 South Main St.

    "A release this week from the city announced the award from DEEP and explained the purpose of the project.

    "Removing the dam will restore the natural flow of #HopevillePondBrook, a tributary of the #NaugatuckRiver within the #LongIslandSound #watershed.

    "The project aims to improve #AquaticHabitat, reconnect #StreamCorridors, reduce #FloodRisk and eliminate a deteriorating structure that poses safety risks for nearby properties and infrastructure, according to city officials.

    "It will take approximately one year to complete the planning, design and permitting phase. Then, the construction will move on to bidding.

    "On Wednesday, Waterbury Mayor Paul Pernerewski, Jr. said the grant represents another significant investment in the city’s infrastructure and #EnvironmentalStewardship.

    " 'Removing the Risdon Dam will improve the health of Hopeville Pond Brook, reduce flood risks and help restore a more resilient #ecosystem for #FutureGenerations,' Pernerewski said.

    "The mayor also thanked #DEEP for its support and collaboration in helping the project move forward.

    "DEEP Commissioner #KatieDykes, who will be leaving her position this month, said the project marks the state’s commitment to protecting and ensuring the health and perseverance of its waterways and the Long Island Sound Watershed.

    " 'Supporting the planning, engineering and design needed to move this project toward construction will help advance future improvements to #StreamConnectivity, aquatic habitat and #FloodResilience,' Dykes said.

    "The funding was made available to DEEP through the U.S. Environmental Protection Agency’s Long Island Sound Partnership National Estuary Program."

  3. Advancing Detailed Flood Hazard Identification in Alberta, Canada - Insights from Two Recent Flood Studies

    “The increasing frequency of floods and the severity of their consequences for public safety, infrastructure, and the economy demand improved methods for flood hazard identification. Flood studies that include flood hazard mapping are critical tools for informing emergency response and flood recovery, as well as for land use and mitigation planning. The methodology for such flood studies has evolved, and access to more powerful computational resources and high-resolution base data has contributed to the increased use of two-dimensional hydraulic modelling, where one-dimensional modelling previously was the default. However, local-scale flood studies face real-world constraints, including sparse data, challenging hydrologic conditions, and budget limitations, which can hinder the application of advanced techniques. This study addresses these challenges through innovative, practice-driven solutions in two case studies in Alberta, Canada: a small, partly channelised prairie stream network (Wolf Creek, Lacombe) and a laterally dynamic river on a distributary delta (Swan River, Kinuso). Three core components of flood hazard studies are described: field survey data collection, regional hydrology assessment, and hydraulic modelling. Key findings include demonstrating that LiDAR-derived terrain models alone cannot capture channel conveyance, the importance of low-flow calibration in the absence of high-water marks, the selection of a modelling methodology based on bathymetric and topographic features within a study area, and the development of inflow hydrographs for unsteady-state simulation in flat floodplains…”

    It would certainly be interesting to organize a similar workshop in #Canada, with a lot of work on-going in #icejam #modeling, both from a #floodhazard and #floodrisk perspective
