Method synopsis

Longitudinal grab sampling along Coal Creek mainstem during three critical hydrograph stages (peak flow, falling limb, low flow) across multiple years to characterize spatial and temporal variability in stream chemistry.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Hidden features: How subsurface and landscape heterogeneity govern hydrologic connectivity and stream chemistry in a montane watershed (2025), Hydrological Processes. Implementations in other papers (listed below) may differ.

1. Collect stream water samples during synoptic sampling campaigns
   Synoptic grab samples were collected longitudinally along the mainstem of Coal Creek as part of the Watershed Functions SFA core operations. Samples were collected during three critical stages of the hydrograph: peak flow, falling limb, and low flow conditions throughout the summer. The most upstream sampling location was the CC5 site, and the most downstream sampling location was the COAL15 site. Stream samples were collected during three critical stages of the hydrograph throughout water years 2020-2023.
   Quantities: Samples collected from approximately 8 stream sampling locations spanning a three-kilometer reach of Coal CreekDuration: Summer seasons (June-September) from 2020-2023Conditions: During peak flow (typically early June), falling limb, and low flow conditions
   Equipment: acid-washed 120mL HDPE Nalgene bottles, 0.45-μm Nylon filters
