This week: restoring the Tweed River in Vermont, 3D modeling of the Yuba, Thailand’s flood defense effort, and ways to stop multitasking.
The Tweed after Irene: How to repair a ruined river (Burlington Free Press) HT: Channel Restorationist
The basic work we could do was to get people to stop digging — stop digging an 80-foot-wide channel in a 30-foot-wide stream! We would redirect them to fill back in to get the dimensions of the channel right. Get that superstructure right. With that, the river can rebuild over time…

Creating a model of about three-quarters of a mile of the river, he said, helps scientists and engineers determine whether the river is the kind of neighborhood the fish will move back into.
One of the seven projects is a 10 billion baht plan to plant trees and build dikes along upstream tributaries of the Chao Phraya. Another, costing 50 billion baht, involves the construction of reservoirs in the river basins where the floods developed.
As it turns out, however, multitasking messes with your brain. Research shows that people who multitask a lot are “more susceptible to interference from irrelevant environmental stimuli and from irrelevant representations in memory” (Ophir 2009).
