Stream Functions Pyramid and Quantification Tool Workshop (Online Version) 

Workshop Description

This course is for individuals involved in stream assessment and restoration/mitigation projects and provides a framework for assessing stream functions. Participants will learn that stream functions follow a hierarchical structure, which has been organized by the following categories: hydrology, hydraulics, geomorphology, physicochemical and biology. The course starts with lectures and exercises on stream functions following the Pyramid Framework and then moves into applications. Participants will work with function-based parameters, measurement methods (metrics), and associated reference standards.

Participants will also work with the Stream Quantification Tool (SQT) to calculate the difference between a restored and existing stream condition. Field data will be provided and enterted into the tool to determine the existing condition. Participants will then model the proposed condition to calculate functional lift.

Learn how the framework can be used to:

  • Improve project goal setting by focusing on stream functions rather than changes to dimension, pattern and profile;
  • Run the SQT to determine functional loss or gain; and,
  • Develop stream mitigation debit and credit determination methods.  

The workshop includes lectures, classroom exercises, and discussion.
