A Few Good Reads (1/23/12): Restoration After Irene

This week: restoring the Tweed River in Vermont, 3D modeling of the Yuba, Thailand’s flood defense effort, and ways to stop multitasking.

Jim Ryan, a state river scientist, surveys a restoration project on the Tweed River in Pittsfield on Friday, Dec. 2, 2011. Floods triggered by Tropical Storm Irene sent the river shooting into a new path that threatened a mill downstream. Road crews seeking gravel further altered the river, making it more unstable. To restore the Tweed, river scientists redesigned a 1,800-foot stretch of the stream, to make it more stable, protect private property and restore fish habitat. Ryan stands on gravel used to fill in the Irene flood channel. That area will be the river's new floodplain -- a relief valve during heavy rains and spring snowmelt. The river flows in its new, more stable channel farther from houses and Vermont 100.

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).
