Why does the Red River of the North have so many floods?
The geology, geography, and climate of the Red River Valley make major floods an inevitability.

Pakistan floods: Predicted or Predictable, but a disaster nonetheless
A Geophysical Research Letters paper concludes the 2010 Pakistan floods were predictable, but not predicted. Other reporting suggests they were predicted, but the warning was ignored. Either way, things should have been done differently.
Flooding around the world
Flooding updates from New Zealand, Australia, South Africa, Saudi Arabia, and Brazil.
Flooding in Pakistan
For the past two weeks, unusually heavy monsoon rains have deluged Pakistan, resulting in flooding and landslides. Pakistan is heavily populated all along the Indus River valley, so this is a slow-moving disaster of epic proportions. The latest news reports estimate that flooding has displaced 14 million people – more …
Anne's picks of the June literature: Fluvial Geomorphology and Landscape Evolution
How do rivers erode bedrock streams, during big floods, and in the presence of groundwater? Laboratory and accidental experiments are providing some cool new insights.
When it rains a lot and the mountains fall down
Cross-posted at Highly Allochthonous The geo-image bonanza of this month’s Accretionary Wedge gives me a good reason to make good on a promise I made a few months ago. I promised to write about what can happen on the flanks of Pacific Northwest volcanoes when a warm, heavy rainfall hits …
A selected few Eyjafjallajokull links
The eruption of Eyjafjallajokull (which means Island Mountain Glacier in Icelandic) started out in March as a relatively quiet and tourist-friendly Hawaiian style eruption. That petered out and then a few days later, the magma reemerged subglacially, producing the spectacular ash-producing phreato-magmatic eruption that has transfixed the world and stranded …
My picks of the December literature
Cross-posted at Highly Allochthonous I’m a few days behind on sharing my picks from December’s journals, but Chris has been doing such a stupendous job of sharing absolutely wonderful geology posts (and of deconstructing terrible science reporting), that I hardly feel guilty waiting until he’s occupied with travels before sneaking …
Megafloods from Glacial Lake Missoula
[Cross-posted at Highly Allochthonous] If I had a time machine and could go back to any point in geologic history, as supposed in this month’s Accretionary Wedge call, the event I’d most like to see is the repeated flooding of the Pacific Northwest at the end of the last Ice …
AGU Abstract Submitted: Secular Streamflow Trends in Watersheds Receiving Mixed Rain and Snow, Pacific Coast and Cascades Ranges
The following abstract was submitted for the Fall AGU meeting: Secular Streamflow Trends in Watersheds Receiving Mixed Rain and Snow, Pacific Coast and Cascades Ranges A. Jefferson, University of North Carolina at Charlotte Much existing research has focused on detecting climate change effects on snowmelt-dominated watersheds, but in the Pacific …
