This is how Qatar 🇶🇦 cheated against India 🇮🇳 during the FIFA World Cup Qualifiers 😯

Today, Qatar suffered a 6-0 defeat against Canada, and two Qatar players received red cards 💥

Group B Points Table:
1) Canada
2) Switzerland
3) Bosnia
4) Qatar

The best flood-mapping AI may be the one we stop allowing to invent impossible water.

Most satellite flood maps do one thing well: they show where the water appears to be. Take Sentinel-1 radar, add optical imagery when clouds allow, classify each pixel, and produce a flood mask.

I guess that’s useful during a disaster, but it leaves out some pretty important factors - how deep the water is, how fast it’s moving, and whether the flood pattern makes physical sense.

A new paper tackles that harder problem.

They present a model which combines Sentinel-1 radar, Sentinel-2 optical imagery, and terrain information from a digital elevation model. That terrain layer includes elevation, slope, and HAND, which measures how high each location sits above the nearest drainage path.

Then the authors use a hybrid architecture: UNet plus FNO.

UNet is pretty good at local details. It can pick up flood edges, roads, urban structure, and small changes in inundation patterns. FNO is better at broader spatial relationships, such as upstream-downstream structure and basin-scale flow.

That combination is useful because floods don’t happen at one scale. A road embankment can shape the water in one neighbourhood, while the slope of the whole floodplain controls where the water wants to go.

But what I find to be the strongest part of the paper is the discussion on physics loss.

The model predicts water depth and velocity, then training checks those predictions against the depth-averaged shallow-water equations. In plain terms, the model gets penalised when it draws floodwater that looks plausible in an image but breaks the rules of mass, momentum, slope, and friction.

That constraint appears to do real work.

Across three held-out floodplain regions, the hybrid model reached an IoU of 0.82 and an F1 score of 0.90.

The depth results are more interesting. Evaluated against HEC-RAS hydrodynamic simulations, the hybrid model reached a water-depth RMSE of 0.21 m.

For flow velocity, the hybrid model reached 0.15 m/s RMSE. It also kept relative mass imbalance down to 2.1%, which is exactly the kind of check you want when a model is pretending to understand water.

Anyway, it looks like the trend is that flood AI models is moving from image classification to physical state estimation. This essentially resembles more traditional hydraulic modelling approaches to the problem. Maybe we're coming full circle...

Liverpool want to be an aggressive, front-foot team led by someone who is all in, whose identity is intensity, who will immerse himself in the club through to the academy, and whose hard-working character will endear him to the city. That’s Andoni Iraola.

Yes, there are risks. There usually always are bar very rare circumstances. Jürgen Klopp thought he was a risk because he had never worked outside of Germany.

Looking at win percentages as a mark of appointing a new head coach/manager is nonsense. Klopp would have never been approached by Bayern Munich or joined Borussia Dortmund in that case.

Luis Enrique would have never gone from Celta to Barcelona.

It’s about what they’ve achieved relative to means, scaling that, plus their stylistic fit to the club and its ambitions.

The wonderful thing about economics is that one can argue the opposite as well. For example, the renowned economist JP Murugan says that a stronger rupee is a sign of strong economy and it’s strategic because makes imports cheaper and lowers inflation as India imports 80% of its oil. A stronger currency also makes international travel and foreign education cheaper and it reduces the debt burden of Indian companies, which borrow in foreign currencies. A strong currency is a sign of economic strength and devaluation is a bad idea.

We don’t support because it’s easy. We support because it’s Liverpool🔴

I have been in dressing rooms that felt this kind of pressure. You feel the noise, the doubt, the headlines. But you also feel the energy from those who support. That’s what carries a team through.

So yeah… things might not look great right now. But that’s exactly when a team needs its people the most.
