1 https://engineering.purdue.edu/~ldc WEB-BASED LOAD DURATION CURVE Indrajeet Chaubey Purdue University Presented at the EPA Region 5 TMDL Practitioners Workshop April 20, 2008

2 https://engineering.purdue.edu/~ldc Collaborators Christine Urban – EPA Region 5 Bernard Engel, James Hunter, Joseph Quansah, Larry Theller – Purdue University K.J. Lim – Kangwon National University Stacy Goodwin – IDEM Thomas Over - USGS

3 https://engineering.purdue.edu/~ldc Flow Duration Curve (FDC) Flow Duration Curve (Adapted from USEPA, 2007)

4 https://engineering.purdue.edu/~ldc Flow Duration Curve (FDC)  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: 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%)

5 https://engineering.purdue.edu/~ldc 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
