Investigate standard and emerging techniques for optimising gauge locations, collecting valid stream gauge data in the field, and applying 1D, 2D, and 3D modelling techniques to develop, refine, and calibrate rating curves.

Take a deep dive into the "black box" of what's behind a rating curve. When a given stage corresponds neatly to a single discharge rate in a uniform system, rating curves can be quite simple. But reality is seldom uniform! In this course, we start with simple cases and expand into more complex curves that account for braiding, storage, backwater effects, seasonal impacts, geomorphic changes, and other phenomena that can significantly affect the reliability of rating curves.

Step through worked examples from scratch, take virtual field trips to existing and prospective gauging sites, and work out confidence bands for compiled data from measurements and models. The course materials convey the underlying fundamentals of hydrology and hydraulics in the application of proper methodologies.

Completing this course will allow you to develop further skills in:
- evaluating streamflow data,
- determining trends and confidence bands,
- establishing reliable relationships between storage and discharge.
