Hydrology Field Work 2019
The stream cross-section profiles in the Andrews Experimental Forest study (see more at dataset GS002) was established to monitor long-term changes in channel cross-sectional geometry (width, depth) in response to storms and change in the disposition of large organic debris in a range of stream sizes beginning in 1978. These observations can be used to assess change in sediment storage within the sample reach and change in habitat structure. OSU graduate student Arianna Goodman resampled the cross sections in 2019 as part of her graduate study.
The Watershed 02 stream gage (see more at dataset HF004) was set up in 1952 as part of a larger paired, gaged watershed study to detect changes in streamflow due to watershed treatments. Data continue to be collected on streamflow and stream chemistry from the gage. Sediment data from the stream is measured periodically to assess load and accumulation. See more about the Experimental Watersheds and Gauging Stations at the Andrews Forest.
Paige is a PhD student from Indiana University studying how water moves into and out of the hyporheic zone in Watershed 01. Paige’s research builds on decades of past research that has taken place in WS01 and extends our knowledge of what drives hyporheic exchange in mountain streams.

Instrumentation in Watershed 2: The Campbell Scientific CR-1000 data logger collects stream stage (i.e., water depth) in the flume, air temperature, water temperature, and water conductivity data. It also triggers the automated Hach/Sigma water sampler to sample, based on stage height. The water samplers are set up as proportional samplers to sample more often as the stream stage rises. The data logger keeps track of when the sampler is to collect a sample. The CR10X data loggers were installed in 1999. The Cr-10x's data loggers were replaced with CR-1000's in 2015.
