Can These Rocks Reduce Flooding? [USGS video]

“Creating a binational sponge city in the desert: Flooding in the binational cities at Ambos Nogales on the Arizona-Sonora portion of the US-Mexico border has caused damage, ruined livelihoods and taken lives for hundreds of years. New research suggests that flooding can be detained using low-tech, nature-based solutions, like natural infrastructure in dryland streams (NIDS), rock detention structures and green infrastructure.…”

CelloMom On Cars

After #HurricaneMilton:

"Her car was fully submerged by heavy rains. Water seeped in under the floors of her home and sewage spewed out of her shower drain.

Maps drawn up by the Federal Emergency Management Agency show that Vacante’s home is not in a “#FloodRisk zone.” "

#Flooding is a challenge affecting everything from economic security, to drinking water & the pursuit of truth & reconciliation. #Canada must adapt to the urgent risks posed by worsening floods. Luckily, numerous pathways exist for individual #Canadians to engage in #CollectiveActions to protect ourselves & our communities.

#ClimateChange is shifting how water moves through landscapes both in our #communities & around the globe. #Information & #awareness is key in this world of changing conditions. However, a 2022 #audit of #FloodRisk preparedness in #Ontario reported that public awareness of personal flood risk & #liability is poor across the province.

Many Canadians are just one bad storm away from an unmitigated watery #disaster. Floods are the most expensive & most frequent type of #NaturalHazard in Canada. An analysis of #insurance solutions for flood risk found that current residential flood risk in Canada is estimated at $2.9 billion per year.

#NatureBased #CommunityDriven #solutions have huge potential to address gaps in #infrastructure, promote resilience & build #ecological knowledge—often at a much reduced cost than traditional hard solutions like seawalls or embankments.

#GreenInfrastructure can also be highly effective along #watercourses where, once established, vegetation helps to filter surface #pollutants, stabilize #erosion & prevent surges of water from spilling over.

Just to add to this #stormwater overland flow #Floodrisk story for #Melbourne. I asked a question at #MerribekCouncil meeting on Wednesday on the 12,000 properties at risk of #flooding in #Merribek in climate driven extreme rainfall events. Merribek is doing better than Yarra, but questions remain. My write up: #ClimateCrisis

Climate Action Merribek · Flood Risk climate impacts: 12,000 Merri-bek properties at stormwater flood risk due to Climate CrisisNews broke on Monday from Yarra Council meeting agenda that new stormwater flood map modelling designate 22,179 properties as being liable to flooding – just over a third of the 60,037 properties i…

The key line from Alastair Chisholm last month from CIWEM's recent Fresh Water Future report:

"Recently it dawned on me that the sad irony contained within A Fresh Water Future and its findings is that there really is nothing fresh in what it says. It has all been said before. Many times."

The consensus is here, let's see the action.
