  1. WEB-BASED LOAD DURATION CURVE Indrajeet Chaubey Purdue University

  2. Collaborators Christine Urban – EPA Region 5 Bernard Engel, James Hunter, Joseph Quansah, Larry Theller – Purdue University K.J. Lim – Kangwon National University S. Goodwin – IDEM Thomas Over - USGS

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

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

  5. Web-Based Flow Duration and Load Duration Curve Tool

  6. 1. Enter/Upload Flow Data for FDC This option lets you enter your own flow data directly on the spreadsheet This option lets you upload your own flow data from an existing file

  7. 1A. Enter Flow Data for FDC FDC – Analysis Flood Conditions 100 cfs Flow Duration Curve (2002-2007) for USGS Gauge 04180000, Cedar Creek, IN

  8. 1A. Enter Flow Data for FDC You can download the dataset by Clicking on this button You can click on the graph/image to save it on your computer

  9. 2. Enter / Upload Flow and WQ Data for LDC This option lets you enter your own flow and WQ data directly on the spreadsheet This option lets you upload your own flow and WQ data from an existing file

  10. 2A. Enter / Upload Flow and WQ Data for LDC You can type your own description here You can type water quality pollutant name here WQ unit can be ppm, ppb or count/100ml Flow unit can be either cms or cfs Date should be in yyyymmdd format You can enter WQ standard or criteria value Clicking this button will create the FDC and LDC

  11. 2. Enter / Upload Flow and WQ Data for LDC FDC –Analysis Flood Conditions 100 cfs Flow Duration Curve (2002-2007) for USGS Gauge 04180000, Cedar Creek, IN

  12. 2. Enter / Upload Flow and WQ Data for LDC FDC – Result Analysis LDC (2002-2007) for Ammonia at USGS Gauge 04180000, Cedar Creek, IN

  13. 2. Enter / Upload Flow and WQ Data for LDC FDC – Result Analysis WQ Target (0.10 ppm) Target Concentration Graph for Ammonia at USGS Gauge 04180000, Cedar Creek,

  14. 3. Retrieve USGS Flow Data and Enter /Upload WQ Data for LDC 3 This option lets you use Google to select a USGS Gauge and directly upload flow data into the tool This option lets you enter a USGS Gauge number to directly upload flow data into the tool

  15. 3A. Retrieve USGS Flow Data and /Upload WQ Data for LDC You can click here to retrieve USGS flow data

  16. 3A. Retrieve USGS Flow Data and Enter /Upload WQ Data for LDC 3 Select beginning and Ending dates Click this button to Generate FDC only

  17. 3A. Retrieve USGS Flow Data and Enter /Upload WQ Data for LDC You can type your own Description here Flow unit can be either cms or cfs Select beginning and Ending dates WQ unit can be ppm, ppb or count/100ml You can type water quality pollutant name here You can enter WQ standard value Click this button to Generate LDC

  18. 4. Using USGS Flow Data * Drainage Area Ratio and Entered /Uploaded WQ Data for LDC Enter Watershed Area-Ratio This option lets you enter a USGS Gauge number to directly upload flow data into the tool This option lets you use Google to select a USGS Gauge and directly upload flow data into the tool

  19. 5. Enter Flow and WQ Data for LDC with Surface-runoff and Estimated Loads You can type your own Description here WQ unit can be ppm, ppb or count/100ml Select Aquifer Type Date should be in yyyymmdd format Flow unit can be either cms or cfs
