Abstract

Time series of tracer (Rhodamine WT) concentration data representing a "break-through curve" resulting from a single, multi-scale tracer test conducted along the length of Lookout Creek, from its 2nd-order headwaters through its 5th-order main stem. The longitudinal tracer test involved an in-stream injection of Rhodamine WT over 78 hrs, followed by monitoring at eight downstream locations for five months, starting in mid-June 2003 through the middle of November 2003. The injection site was located below the upper Old Growth Trail bridge. The monitoring sites include one downstream of the injection site, above and below the Cold Creek confluence, below the lower Old Growth Trail bridge, below Mack Creek confluence, above and below McRae Creek confluence, and at the HJA headquarters. Three additional inter-order tracer tests (IOTT) were carried out between each of the major stream confluences along Lookout Creek. The injection site for the McRae Creek IOTT was located below the McRae Cr. confluence and was monitored just downstream, at the end of the main floodplain, and at HJA headquarters. The injection site for the Mack Creek IOTT was located below the Mack Cr. confluence and was monitored just downstream, at an unnamed tributary midway between Mack Cr. and McRae Cr., and above the McRae Cr. confluence. The injection site for the Cold Creek IOTT was located below the Cold Cr. confluence and was monitored just downstream, at Longer Cr., and at the lower Old Growth Trail bridge. Concentration break through curves are available for all of the monitoring sites for the longitudinal and inter-order tracer tests. Flux break through curves are available for most of the monitoring sites. STAMMT-L model estimates for hyporheic exchange is listed for most of the monitoring sites.

Purpose
  • The primary goal of this research project is to quantitatively measure the temporal scales of hyporheic exchange along a stream network. Our goal is to examine how hyporheic exchange varies with increasing stream size. Many previous studies focus on single stream reaches or on several reaches of similar sized streams, whereas we examined the residence time of water in the hyporheic zone over increasing length scales in a single stream. Prior work with tracer data and analysis using a transient storage model with an exponential residence time distribution (RTD) suggests that hyporheic parameters, primarily volume and mean residence time, are both spatially and temporally scale-dependent. However, recent work hypothesizes that the scale-dependence may be partially addressed by using a power-law RTD (Haggerty et al., 2002). Our research tests this hypothesis with several multi-scale tracer tests in a single stream.

Abstract
  • The H.J. Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics.
  • Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition.
  • The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources.

Method Steps

Method Step 1

No method step description paragraphs listed.

Instrumentation - HF020
  • The longitudinal tracer test and McRae Creek inter-order tracer test was facilitated by a Fluid Meter Inc. (FMI) DC injection pump (model # RHB1). The Mack Creek and Cold Creek inter-order tracer tests were conducted using a new Fluid Meter Inc. AC injection pump (model # QG150, with a Q1CKC pump head). The discharges in the streams were measured using a Marsh-McBirney, Inc Flo-MateTM flow meter. The concentration of RWT was measured using a Turner DesignTM model 10-AU fluorometers and Teledyne ISCOTM samplers.
Processing Procedure - HF020
  • In order to calculate flux breakthrough curves we needed to have a continuous record of discharge for each site. The discharge hydrographs of each site was estimated using a linear hydrograph regression from gauged watersheds within the H.J. Andrews. The hydrograph watershed regression was accomplished using point discharges gathered by Jeff Ninnemann and Charles Fardy throughout the summer and matched with one of the 10 gauged watersheds for a best fit linear regression. The linear relationship established between individual site discharges and watershed gauge datum was then used to estimate a discharge for each individual monitoring site.

Sampling

Study Extent
  • This study was conducted along the main stem of Lookout Creek in the H.J. Andrews. Monitoring sites included sites below the upper old growth trail bridge, above and below the Cold Cr. confluence, above and below the Mack Cr. confluence, above and below the McRae Cr. confluence, at the first valley constriction below the concrete bridge, and at the Headquarters.
  • The Longitudinal Tracer Test was conducted along the main stem of Lookout Creek. The injection site was located ~30 m downstream of the upper old growth trail bridge. There were eight monitoring sites below the injections site. Three fluorometer sites were stationed on Lookout Creek just up stream of Cold Cr., Mack Cr., and McRae Cr.. The fluorometers were 1032 m (Site 2), 4145 m (Site 6), and 8,907 m (Site 11) downstream of the injection site (as shown in Figure 1). One ISCO sampler was located 84 m below the injection site (not shown on map). Four additional ISCO monitoring sites were established below each of the confluences and near the base of the basin. The ISCO monitoring sites were 1,137 m (Site 4), 5,126 m (Site 7), 9,327 m (Site 12), and 14,274 m (Site 14) (Figure 1).
  • Three additional tracer tests were also conducted between each major confluence within Lookout Creek. These inter-order tracer tests encompassed changes in stream scale from a 3-order drainage basin to a 5-order drainage basin.
  • The first inter-order tracer test was a conducted between the confluence of McRae Creek and the H.J. Andrews headquarters. The injection site was located ~150 m downstream of the McRae Creek confluence (site 11). This tracer test was monitored 5,367 m downstream at the H.J. Andrews headquarters with a fluorometer (Site 14). The concentration of dye was also monitored 1,465 m downstream by an ISCOtm sampler at a position in the stream where the geomorphology changes from a floodplain to a constrained valley (Site 13). An additional ISCO sampler was located 420 m below the injection site (Site 12).
  • The second inter-order tracer test was a conducted between the confluence of Mack Creek and McRae Creek. The injection site was located ~25 m downstream of the Mack Creek confluence (site 7). This tracer test was monitored 3,457 m downstream above the McRae Cr. confluence with a fluorometer (site 10). It was also monitored 1,001 m downstream by an ISCOtm sampler at the largest tributary between Mack and McRae Cr (site 9). An additional ISCO sampler was located 25 m below the injection site (Site 8).
  • The third IOTT was a conducted between the confluence of Cold Creek and Mack Creek. . The injection site was located ~10 m downstream of the Cold Creek confluence (site 3). This tracer test was monitored 3,054 m downstream at a site above the Mack Cr. confluence with a fluorometer (site 6) and 2,105 m downstream by an ISCO sampler at Longer Cr.(site 5), the largest tributary between Mack and McRae Cr.. An additional ISCO sampler was located 46 m below the injection site (Site 4).
  • Sampling frequency: a range of every 30 seconds to monthly
Sampling Description
  • Stream discharge at the injection sites during the injections for the longitudinal tracer test and the inter-order tracer tests were measured by wading, using a Marsh-McBirney model 200 flow meter (Marsh-McBirney, Inc., Fredrick, MD, USA). Stream discharge during the duration of the tracer tests was measured at the USGS gauge house at the below headquarters on Lookout Creek. Hydrograph regressions were used with gauged watersheds within the H.J. Andrews to estimate a continuous discharge for all sites. Turner DesignTM model 10-AU fluorometers (Turner Designs, Inc, Sunnyvale, CA) were used to monitor concentrations at some sites. All samples collected with ISCO auto samplers (ISCO, Inc., Lincoln, NE) were analyzed with the same Turner Designs fluorometers (Turner Designs, Inc, Sunnyvale, CA). Four continuous injection tracer experiments were performed over various lengths of Lookout Creek in the HJ Andrews Experimental Forest.
