The Stream Quantification Tool (SQT) quantifies the functional difference between existing, proposed, and monitored stream restoration projects. Based on the Stream Functions Pyramid Framework, the tool applies performance standards to metrics within five functional categories: hydrology, hydraulic, geomorphology, physicochemical and biology. North Carolina, Wyoming, Georgia, Tennessee, and Michigan use the SQT and efforts are underway to adapt the tool for use in several other states. Thus far, regionalization of the SQT is has focused on single-thread channels. This presentation summarizes a case study using the SQT to quantify functional lift on a perennial stream in the Maryland Coastal Plain where a valley restoration approach will be implemented. This case study will highlight the strengths of the SQT in quantifying functional lift in stream-wetland complexes while also identifying opportunities to improve the SQT for use in multi-thread, stream-wetland complexes.
