You're on it. The region manages a lot of its rainfall-driven flood risk by quickly infiltrating water into the ground, which is highly porous. But if there's no space in the ground to put it, due to a higher ground water table, then the water spreads out on the land surface.

A new model formulation for fast, high-res (<3m), physics-based flood simulation over large areas (> 1,000 km2) with groundwater interactions and hydraulic structures. More work to come informing adaptation in both Miami and Los Angeles. w/ @katharinemach.bsky.social

Mud and debris hazards in Southern California are generated when loose material in mountain canyons, released from hill slopes with the burning of vegetation, is mobilized by streamflow. An illustration w/ Eaton Canyon above Altadena. Note the critical role of debris basins - protecting communities.

A postscript: this work was funded by the now "archived" Humans, Disasters and Built Environment program at the National Science Foundation.

This work reinforces the need for risk communication efforts by governments and others to emphasize the actions that are effective and are within the capacity of residents. This work also highlights the need to build capacity where it is lacking.

Two major findings here: (1) increasing risk awareness among residents DOES NOT translate into behavior that mitigates risks, and (2) residents WILL take action when: (a) they know what they are doing will work, and (b) they have the capacity to do so.

Like Texas, California faces major dangers when extreme floods come The flood disaster in Texas claimed dozens of lives. Extreme floods also bring dangers in parts of California, although experts say there are differences.

@floodlab.bsky.social examined flood hazard maps and found that the summer camp's cabins were within a federally designated “floodway.”

"There was a breakdown somewhere along the way, in the understanding of risks and the ability to take action in a timely way." www.latimes.com/environment/...

A welcome spotlight on the value of graduate education.

Opinion: After the Los Angeles fires stop burning, another grave risk to lives and property looms Mudslides and debris flows are a risk around Altadena, Pacific Palisades and other areas affected by the wildfires, which can destabilize mountain slopes.

Mudslides and debris flows following wildfires can be more deadly than the fires themselves. Communities are protected by debris basins, but they are prone to overtopping. An "explainer".

OK. This is really bizarre. Is this how all businesses are going to engage Trump?

Tiktok is off, but Trump will come to the rescue. Good grief.

I still can’t believe this is all happening in JANUARY.

Supreme Court may sharply limit the scope of environmental impact statements The conservative-leaning Supreme Court has steadily ruled against environmental regulation and may be about to do so again.

How will this impact the pace, direction and effectiveness of climate adaptation? #adapt

Early start to Day 1 at AGU. Hope to see you in our floods sessions today.

I'm pleased to share a commentary paper co-authored by Oliver Wing and Paul Bates, and published today by Earth's Future, calling for an end to bathtub modeling in flood risk studies. Ready why here:

Thankful to see an unarmored river in coastal California. Happy Thanksgiving from Paso Robles! @adaptationhive.bsky.social
