Computer networks and the industrial control systems that raise dam gates, operate pumps, disinfect drinking water, and guide an assortment of other critical functions are vulnerable to the digital version of breaking and entering. In the evolving realm of cybersecurity, where the risks today are different than just a few years ago and the threats tomorrow will be different still, a utility's size may not be the most important characteristic for those looking to do harm.

Stanford algorithm calculates groundwater levels

Stanford University

A new computer algorithm — which can "fill in" underground water levels in areas where data is not available — developed at Stanford University is enabling scientists to use satellite data to determine groundwater levels across larger areas than ever before. The technique, detailed in the June issue of the journal Water Resources Research, could lead to better models of groundwater flow.
