Watershed Diagnostics Branch (WDB)
The Watershed Diagnostics Branch conducts research to develop the quantitative tools and models needed to identify and characterize causes of aquatic system impairment. Research focuses on determining the primary characteristics of impairment caused by individual stressors and classes of stressors including nutrients, determining the mitigating or exacerbating effects on impairments of watershed attributes, and establishing the scientific basis for identifying appropriate scales for geographic aggregation of impaired waters in support of TMDL (Total Maximum Daily Load) development.
