China’s Great Dam Boom: An Assault on Its River Systems

EarthzineWater

Originally Published by Yale Environment 360- China is engaged in a push to build hydroelectric dams on a scale unprecedented in human history. While being touted for producing lower-emission electricity, these massive dam projects are wreaking havoc on river systems across China and Southeast Asia.

Originally published by Environment News Service – Two companies involved in the 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico, the largest in U.S. history, have attempted to withhold evidence from investigating authorities, but one must now produce the documents sought, and the other is being penalized for destroying a separate set of evidentiary facts.

Removing pollutants and contaminants from wastewater

EarthzineWater

Originally published by ScienceDaily – The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and its European partners have developed several effective processes for eliminating persistent pollutants from wastewater. Some of these processes generate reactive species which can be used to purify even highly polluted landfill leachate while another can also remove selected pollutants which are present in very small quantities with polymer adsorber particles.

Figure 3: Average daily rainfall (shaded and units of millimeters) from June-August (200-2006) composited for days with weak atmospheric forcing (lef). The 5 mm contour is shown in blue and the yellow boxes represent the mean upwind (left box), city (center box), and downwind (right box) regions. Lightning flash anomalies (May to September, 1995‰ÛÒ2003) on days dominated by weak atmospheric forcing (right) in Atlanta, Georgia. Image sources: [4] and [5], respectively.

FIG4 A recently concluded research project called MAMUD investigated how high and moderate resolution satellite imagery can be used for mapping and modeling urban growth and its impact on the hydrology of the urban and suburban environment. The paper focuses on research methods, major findings, and work carried out on the Greater Dublin Area in Ireland.
