“… [U]rban floods are not merely hydraulic events; they also transport sewage, pathogens, and other contaminants across streets and communities, leading to significant public health risks…
How do we quantify microbial contamination in near real time during a flood event, when emergency conditions make field sampling unsafe, sparse, or even impossible?...
[The authors] explored whether Earth observation data, combined with machine learning, could bridge this critical monitoring gap. By combining Landsat-derived water surface temperature, machine learning, a coupled MIKE+ Flood–ECO Lab hydrodynamic–ecological model, and Quantitative Microbial Risk Assessment (QMRA), [they] estimated microbial concentrations (𝘌. 𝘤𝘰𝘭𝘪), simulated their fate and transport during floods, and quantified the associated human health risks.
The takeaway: predicting flood risk isn't just about where the water goes; it's about what it's carrying and who it puts in harm's way. Earth observation and machine learning can help close that gap when it matters most, during the emergency, not weeks after…”

#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."

#Vermont #DamRemoval Program Reclaims #Floodplain
Crews removed a century-old #WestRutland, Vt. dam to prevent flooding
By Johanna Knapschaefer, October 16, 2025
Excerpt: "Reclaiming Floodplains
Removing the Young’s Brook Dam—the source of safety and flooding hazards for decades—could restore more than half an acre of flood plain. Mary Ann Goulette, West Rutland’s town manager, says the dam’s 'removal not only reduces risk to homes, businesses, and infrastructure downstream, but also restores a natural river system that will serve us far better in the face of increasingly severe storms.'
"In that spirit, the Flood Safety Act will authorize the state to preclude development within the #RiverCorridor for dams removed from a stream site with a drainage area greater than two square miles helping to 'manage stream and floodplain processes toward a more natural equilibrium state,' says Mike Kline, a member of the Vermont Dam Task Force who spearheaded the act after retiring from a 30-year career in the Vermont Dept. of Environmental Conservation.
"Kline says dams can disrupt natural sediment transport processes in streams, leading to more sediment deposition in some places and greater erosion in others. Removing dams with impoundments allows for the creation of 'floodplains that function to store floodwaters and promote greater equilibrium between erosion and deposition, thereby reducing fluvial erosion during flood events,' he says."

“… In hilly regions transitioning rapidly to low gradient alluvial plains, localized hydrometeorological triggers can instantly scale into devastating basin wide disasters. This study dissects the September 2020 cascading hazard in parts of the Arunachal Pradesh-Assam corridor to quantify the rapid coupling between upstream hillslopes and downstream floodplains.

“Extreme precipitation in the Eastern Himalaya is increasingly associated with coupled hillslope-floodplain hazards. This study examines the 17th-18th September 2020 rainfall event in Arunachal Pradesh initiating landslides and its downstream impacts in Assam, India, using multi-sensor satellite data and long-term rainfall records. Sentinel-2 imagery was used to map landslides and debris flows, Sentinel-1 SAR data to delineate flood extent, and IMD gridded rainfall (1996–2020) to analyse rainfall spell characteristics. The event triggered widespread slope failures, localized landslide damming, and a subsequent breach, generating sediment-laden flows that inundated ~ 100 km² of the Dhemaji floodplain. A backscatter-derived Relative Flood Volume Index (RFVI) indicates spatial variability in inundation intensity, although it does not represent absolute flood volume. Rainfall analysis suggests that antecedent wetness from preceding spells preconditioned slopes, while peak daily rainfall (> 170 mm day−1) initiated landsliding. Power-law scaling shows negligible dependence of intensity on duration (R2 ≈ 0.0004), whereas cumulative rainfall exhibits a stronger relationship with duration (R2 ≈ 0.54). These results indicate distinct roles of rainfall intensity and accumulation in controlling landslide initiation and downstream flooding, respectively, highlighting the importance of compound rainfall forcing in rapid hydrogeomorphic cascades…”

Advancing Detailed Flood Hazard Identification in Alberta, Canada - Insights from Two Recent Flood Studies
--
https://doi.org/10.3390/w18131592 <-- shared paper

“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…”

"PLAIN LANGUAGE SUMMARY: River floodplains are integrative ecosystems in which diverse processes operate together to maintain river health. Floodplains are as critical to river health as the channel itself, yet floodplains lack the legal protections afforded to river channels in many countries.
KEY POINTS
• A river floodplain is an integrative physical, chemical, biological system and a key component of a river corridor
• Contemporary societal perceptions and regulatory frameworks do not reflect this scientific consensus...”

Worth noting for #GoogleMaps users... It has been clear to me for some time that #Google is using machine learning algorithms (sometimes called "AI") to adjust boundaries of geographic features. I assume they run an #ML model over satellite photos to do this. Here's a example of it failing, badly. The first picture attached is a Google Map of an urban creek in my town, with a street just north of it. Note how Google shows the creek not going anywhere near the street. The second picture is a topographic map of the same area. Notice how the creek ACTUALLY goes much farther north than Google depicts. For creeks and bodies of water I've noticed this most often happens where there is an adjacent #FloodPlain that the creek spills into on occasion. Clearly Google's algorithm is noticing water during flood conditions, or breaks in the tree line, and "learning" that the creek has moved. (In their defense, it is quite unusual that this urban creek passes directly under an office building parking deck, which probably also played a part. But why use ML to do this stuff when #topographic data exists?) #AIFails #AIFailures

Diversion Channels vs. Climate Change: Will Five Cities’ Flood Protection Strategy Be Enough?
Many of those reading this post may recall scenes from the disastrous floods that took place along the Red River of the North in 1997, 2009, and 2011. Cities like Fargo and Grand Forks, North Dakota were severely impacted by floodwaters due to snowmelt and ice jams along that northward flowing river. Further north along the same river, in Manitoba, Winnipeg has dealt with significant flooding on multiple occasions.
Fargo flooding in 2011 – Source: wsj.comPart of the problem along this particular river valley is there is very little topographical change in this area, so when river levels run high, the floodwaters spread out far and wide across the northern prairie landscape. The limited grade change also tends to slow the speed of the river’s flow, which can add to the backup.
Tragic water and fire damage to downtown Grand Forks from 1997 flood – Source: grandforksherald.comTo address these costly and dangerous flooding problems along the Red River of the North, both Winnipeg and Grand Forks have developed enormous flood diversion channels around their urban area. Meanwhile, Fargo is close to completing its diversion channel. These three diversion systems are discussed below followed by other diversion channel programs established in Wichita, Kansas and Albuquerque, New Mexico.
Red River Floodway – Winnipeg, Manitoba, Canada = 29 mile diversion channel
- Completed in 1968 for $63 million and enlargement completed in 2010 for $665 million
- Designated a National Historic Site in 2000
- Capacity of 140,000 cubic feet per second
- 2.7 billion cubic feet of Earth moved (more than the Suez Canal)
——-
English Coulee Diversion Channel – Grand Forks, ND, USA = 13 mile diversion channel for English Coulee and 8 miles of flood walls/levees along the Red River of the North
- The diversion channel for English Coulee bypassing Grand Forks was completed in 1990. Unfortunately, increasing the height of flood walls and levees was not completed until 2007.
- Total project cost was $409 million including the flood walls and levees on the Red River of the North.
- Flood protection was raised from 50 feet to 60 feet.
- Flood/stormwaters can be also pumped to the diversion channel from the city — up to 112,000 gallons per minute (= 250 cubic feet per second).
- Twenty miles of greenways trails
——-
Fargo-Moorhead Area Diversion Project – Fargo, ND/Moorhead, MN, USA = 30 mile diversion channel and 22 mile earthen embankment at the southern end of the complex
- To be completed in 2027 for $3.2 billion
- The Red River has reached flood stage in Fargo 60 times since 1902, including every single year between 1993 and 2011.
- Designed to withstand a 100-year flood and provide fightable protection against a 500-year flood.
- Capacity of 20,000 cubic feet per second.
- Other features will include levees, flood walls, stormwater lift stations, road improvements including raising grades, upstream mitigation, wetland mitigation, river restoration, a bike/walking trail, and related flood control projects in outer communities and in nearby Minnesota.
——-
Further to the south, Wichita, Kansas has faced similar issues with flooding from the Arkansas and Little Arkansas Rivers. To limit future damage to life and property in the city, an enormous flood diversion project was completed here in 1959. This diversion channel is very visible to drivers along Interstate 235 around the west side of the city.
Wichita-Valley Center Floodway – Wichita, KS, USA = 18 mile diversion channel
- Completed in 1959 for $20 million
- Includes 50 miles of connecting channels, 100 miles of levees, and 150 control structures.
- The diversion channel has a flood carrying capacity twice that of the Arkansas River itself, while the Little Arkansas River portion around the town of Valley Center has a capacity of 55,000 cubic feet per second.
——–
In an altogether different context, Albuquerque, New Mexico can also face quick and devastating floods, but not from a flat terrain. Instead, the threat here is threefold – rapid snowmelt from the abutting Sandia Mountains flowing down into the city and the valley combined with urban stormwater runoff and heavy summer monsoon-season rains (yes, we have a monsoon season here) overwhelming the natural arroyos and dry stream beds. In Albuquerque, a network of diversion channels has been developed, with two primary ones (the North and South Diversion Channels) being the largest collectors and distributors of stormwater and floodwaters from natural arroyos and human made/enhanced channels.
Monsoon season storm over Albuquerque – Source: flickr.comNorth Diversion Channel – Albuquerque, NM, USA = 8.7 miles
- Completed in 1969 at a cost of $20.3 million
- Capacity of 44,000 cubic feet per second ~ equivalent to a 500-year flood event
- Collects flood/storm waters from 50 square miles and discharges it into the Rio Grande
- A bicycle/pedestrian trail runs along the top of the channel for its entire length.
- Passes through the heart of the city instead of around it.
South Diversion Channel – Albuquerque, NM, USA ~ 5.5 miles
- Completed in 1972 at a cost of $8.3 million and discharges into the Rio Grande
- A bicycle/pedestrian trail runs along the top of the channel for much of its length.
——-
As these five examples show, there are viable options for protecting life, limb, and property from devastating floods in urban areas. That being said, as the Earth’s climate continues to become warmer, bringing with it heavier rainfalls and stronger storms, even these diversion channels and their associated infrastructure may become overwhelmed by future weather events.
Source: climateactiontracker.orgTherefore, addressing only the after-the-fact results of storms will not protect our communities as long as climate change is allowed to continue on its current trajectory. Humankind must also address the root causes of climate change, including the impacts we create by our individual and collective actions and activities. This includes making hard choices…frankly choices that highly-developed First World countries like the United States too often avoid making.
Furthermore, when nations ignore climate reality, these five cities, let alone many others across the planet, will need to upgrade their flood defenses over and over again. In this era of climate change, such efforts will not and cannot solve the problem alone. Humanity must find the “sustainable willpower” to effectively address climate change for the long term. In the end, future generations will be grateful that we did.
Peace!

“... KEY POINTS:
• River meandering resets permafrost development and vegetation succession by eroding old floodplain areas and depositing new land
• On the Koyukuk River, permafrost rapidly forms in new deposits, but it takes over 4 Kyr to develop to its full areal extent of 85%
• The rate of permafrost formation is likely linked to vegetation succession on younger and overbank deposition on older floodplain areas…”
