Water Wars: The 'New Hydronomy'

"The [River Forecast System] is an extended suite of software applications developed by the Weather Service over the past 27 years to predict, up to six months in advance, the amount that will flow through any given body of moving water...It takes the vast array of data (current river levels, reservoir releases, precipitation, air temperature, solar radiation, plant transpiration, to list a few) required to generate a forecast, automates the predictive algorithms, then colorfully represents them in detailed charts and graphs...you can sit in front of a screen and sweep a cursor over a map that shows every body of water in the region...Double-click on...and a line graph will appear, showing how many cubic feet per second passed...during a recent week. Click on the Delaware itself and find out how much water is likely to pass through Philadelphia on Wednesday."
