The Cumulative Frequency Diagram Method for Determining Water Quality Attainment

In accordance with the Chesapeake 2000 Agreement, the Chesapeake Bay Program has recently imple mented important modifications to (1) ambient water quality criteria for living resources and, (2) the procedures to determine attainment of those criteria. A novel statistical tool for attainment, termed the Cumulative Frequency Diagram (CFD) approach, was developed as a substantial revision of prev...

An Overview: Water Quality, Environment and Climate Change

Climate Change Impact on Water Resources and Life Quality

The climate changes represent one of the major challenges in our century with major impact upon human being. This is the reason for which the study of the effects brought about by the climatic changes is one of the most current themes on international level. According to the meteorological events of the last years, Romania will be one of the most affected countries by the climate changes effect...

Climate change mitigation for agriculture: water quality benefits and costs.

New Zealand is unique in that half of its national greenhouse gas (GHG) inventory derives from agriculture--predominantly as methane (CH4) and nitrous oxide (N2O), in a 2:1 ratio. The remaining GHG emissions predominantly comprise carbon dioxide (CO2) deriving from energy and industry sources. Proposed strategies to mitigate emissions of CH4 and N2O from pastoral agriculture in New Zealand are:...
