The forces involved in coastal zone change are difficult to assess and understand. There are now several efforts underway to embed sensors in individual pebbles in order to track them and visualize their location change over time. There have been a number of more passive tracking methods deployed in the past, including acoustic sensors. With [...]

The waterways of Mexico City were first crafted by the Aztecs to manage floods and to form protective barriers. These natural corridors were then heavily impacted by the advent of cars, putting roads above rivers in order to quickly move traffic. Now, an ambitious group of planners are hoping to replace the roads with rivers [...]

Clemson University has deployed sensors and corresponding system software for the Intelligent River project along the Savannah River in upstate South Carolina. Researchers are monitoring 120 miles of river with wireless sensor motes that monitor a wide variety of parameters associated with water quality, pollution and environmental impacts. The way that Clemson approached this problem [...]

More than 200,000 buildings and countless other debris were washed out into the Pacific as a result of the recent tsunami. That wreckage is now being pushed across the ocean by the currents of the North Pacific Gyre with the debris headed toward Washington, Oregon and California, before circulating back toward Hawaii. The average drift [...]

An international team of scientists used imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Tropical Rainfall Measuring Mission (TRMM) sensors over more than a decade to determine the stress of last year’s record-breaking drought on the Amazon’s vegetation. The analysis determined that the vegetation in the large basin went through great stress and is [...]
