HPWREN-enabled hydrologgy sensors at the San Diego State University's Santa Margarita Ecological Reserve

submitted by: Monika

Water quality assessments are becoming more and more critical in Southern California and elsewhere. This video describes ongoing activities related to HPWREN-enabled real-time hydrology sensors at San Diego State University's Santa Margarita Ecological Reserve. Both permanent and mobile approaches are being discussed.

State and Regional Hydrologic Information Systems - presentation by David Maidment & David Tarboton

submitted by: cmatiuk
Maidment & Tarboton: The CUAHSI Hydrologic Information System enables water data to be delivered through the internet in a common language called WaterML, which describes time series of observations measured at a point locations for quantities such as streamflow, water quality, climate and groundwater conditions. Collections of water observations data from a variety of sources are stored in the CUAHSI Observations Data Model and published in WaterML as CUAHSI water data web services....

Pressure bomb

submitted by: schulzbu
This video is a visual 10 step instruction manual how to use a pressure bomb for measuring water pressure in the xylem of transpiring leaves. It is geared towards undergraduate students working in plant physiology labs as well as viewers who are interested in plant biology. Water in the xylem is under negative pressure. This tension can be measured by a “pressure bomb”. Tension pressure in a non-transpiring leaf is “equivalent” to water potential of cells surrounding the xylem...

Scientists From Across the Globe Warn of Drastic Water Shortages

submitted by: ucsandiego
In the Sierra Neveda, snowpack will shrink by 30 to 90 percent by the end of the century. On the other side of the planet, in the Himalayas, about 70 percent of glaciers are set to disappear. These changes are both caused by climate change and will lead to dramatic water shortages for hundreds of millions of people across the globe, scientists said during a press conference Wednesday at UC San Diego.
