Flow Duration Curve (FDC)
Flow Duration Curve (Adapted from USEPA, 2007)
https://engineering.purdue.edu/~ldc
Load Duration Curve (LDC)
Flow Duration Curve (USEPA, 2007)
In compliance
Out of compliance

Web-Based Flow Duration and Load Duration Curve Tool
https://engineering.purdue.edu/~ldc
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
https://engineering.purdue.edu/~ldc
Flood Conditions
100 cfs
Flow Duration Curve (2002-2007) for USGS Gauge 04180000, Cedar Creek, IN
1A. Enter Flow Data for FDCFDC – Analysis
https://engineering.purdue.edu/~ldc
You can download the dataset byClicking on this button
You can click on the graph/image to save it on your computer
1A. Enter Flow Data for FDC
https://engineering.purdue.edu/~ldc
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
https://engineering.purdue.edu/~ldc
2A. Enter / Upload Flow and WQ Data for LDC
You can type your own description here
Date should be in yyyymmdd format
Flow unit can be either cms or cfs
Clicking this button will create the FDC and LDC
WQ unit can be ppm, ppb or count/100ml
You can type water quality pollutant name here
You can enter WQ standard or criteria value
