Sediment Rating Curve Calculation and Considerations
Note: We now have a tool in HEC-RAS that helps with these analyses (mentioned at the end of the video). I posted a demo video here: • HEC RAS Sediment Rating Curve Analysi...
This video covers the motivation behind developing a sediment rating curve, walks through the steps of fitting a power function, and then discusses five important considerations that you should address while developing your rating curve, including:
1. Stationary (9:29)
2. Hysteresis (10:26)
3. Transform Bias (13:40)
4. Supply Limitation (18:50)
5. Serialized Correlation (21:16)
The USGS statistics manual is here: https://pubs.er.usgs.gov/publication/...
And the USGS tool to evaluate Serialized Correlation is here: https://water.usgs.gov/osw/SALT/SAID
