  1. WEB-BASED LOAD DURATION CURVE Indrajeet Chaubey Purdue University Presented at the EPA Region 5 TMDL Practitioners Workshop April 20, 2008

  3. Flow Duration Curve (FDC) Flow Duration Curve (Adapted from USEPA, 2007)

  4. Flow Duration Curve (FDC) • EPA (2007) recommends five hydrologic zones/categories – • High flows (0-10%) • Moist conditions (10-40%) • Mid-range flows (40-60%) • Dry conditions (60-90%) • Low flows (90-100%) • Use: Flow patterns variability assessment in historic flow data • Flow Data Source: USGS, modeling, etc. • Analyzing FDC: Hydrologic condition indicator divisions for FDC depends on the local hydrology and the water quality issues:

  5. Load Duration Curve (LDC) • Use: To understand water quality concentration and load variability for developing TMDLs • Water Quality Data: Federal, State and Educational • institutions, watershed practitioners, etc • Water Quality Standard: EPA, Local Stakeholders • LDC Development: • LDC = Stream flow *water quality target *conversion factor

  6. Load Duration Curve (LDC) Out of compliance In compliance Flow Duration Curve (USEPA, 2007)
