A training course to augment USGS Course H-17-037, Acoustic Index Method for Estimating Fluvial Suspended Sediment and USGS Techniques and Methods Report 3C-5
Version 1.00 – March 2018
Fluvial suspended-sediment characteristics can be computed using acoustic indices derived from backscatter data collected using fixed-mounted, horizontally-looking acoustic Doppler velocity meters (ADVMs). The sediment acoustic index method applied in these types of studies can be used to more accurately and cost-effectively provide time-series estimates of suspended-sediment concentration and load, which is essential for informed solutions to many sediment-related environmental, engineering, and agricultural concerns.
This web-based course will teach hydrographers the basic fundamentals of the sediment acoustic index method, using a single frequency ADVM, and how to establish a sediment acoustic index station. The material presented will summarize and augment information in the USGS Techniques and Methods 3C-5 report “Sediment Acoustic Index Method for Computing Continuous Suspended-Sediment Concentrations”. The course will teach the important aspects of establishing a sediment acoustic index station including the following topics:
This web-based course provides introductory material and is a prerequisite to the full, week-long USGS course H-17-037 Acoustic Index Method for Estimating Fluvial Suspended Sediment. The course also is a valuable refresher for students who are already familiar with the sediment acoustic index method.
The course should take no longer than 4 hours to complete. Students can stop and resume where they left off within each lesson as needed.

Lesson 2: Utility and Overview of the Sediment Acoustic Index Method
By the end of this lesson, the student will be able to:
Lesson 3: Site Selection Criteria and Field Reconnaissance Techniques
Lesson 4: Data Collection Requirements and Recommendations
Lesson 5: Data Corrections and Computations
Lesson 6: Surrogate Analysis and Index Development (SAID) Tool
Lesson 7: Sediment Acoustic Measurement Theory

Final Assessment (DOI Talent)
The final assessment must be taken and passed with a score of 80% or better to attend the classroom portion of the USGS-H-17-037 course. Course coordinators will be able to view completion certificates in DOI Learn. Course coordinators will provide separate instructions to non-DOI employees on how to take and submit results of the final assessment.
