Nice! Can't make this one but would like to join in the future, is there a mailing list?

Yeah I only work on floods where you assume the land surface is fixed, but places that have steep slopes, rich soils, and extreme rainfall tend to have major erosion (yes, not a geomorphologist but maybe why there's no dirt left?) if not deadly landslides

But this does illustrate a few tragic and uncomfortable truths. The first is that even quite good weather forecasts do not automatically translate into life-saving predictions--there's a lot of other work that has to take place to contextualize the forecast and ensure it gets to right people.

Yeah I am primed for this because of Harvey -- Houston *is* a sprawling concrete mess! But drop 40" of rain on a huge flat area and it's going to flood, even without the sprawl.
Hard to imagine the soil type such that 15" of rapid rain on slopes doesn't cause flash flooding

(a) this is an answerable question, so we shouldn't _need_ to rely on my limited intuition
(b) I can hear the geomorphologists saying "there's a reason why you have a thin soil layer there" which is fair, but this is a thought experiment

Also, taking the probability estimates at face value (which I don’t) it matters what variable you analyze. It can be a .2% event of X hour rainfall at one gauge without being a .2% discharge at every gauge
