  • Water Quality Management Using the National Pollutant Discharge Elimination System (NPDES) Watershed Framework: EPA’s New Technical Guidance

    ABSTRACTFor nearly a decade, EPA has supported and encouraged a watershed approach to addressing water quality problems. In December 2002, the EPA Office of Water Assistant Administrator issued a policy memo titled, “Committing EPA’s Water Program to Advancing the Watershed Approach.” Through this memo, EPA reaffirmed its commitment to the watershed approach and reenergized efforts to ensure that ...

  • Agricultural biomass monitoring on watersheds based on remotely sensed data

    There is a close quality relationship between the harmful levels of all three drought indicator groups (meteorological, hydrological and agricultural). However, the numerical scale of the relationships between them is unclear and the conversion of indicators is unsolved. Different areas or an area with different forms of drought cannot be compared. For example, from the evaluation of ...
