Coarse particulate organic matter transport and storage in headwater streams in the Colorado Rocky Mountains, CO, USA.

4 data sets are present:
FIELD SITE: GORDON GULCH
Meta-FieldLog-GG-LF-StorageReachLVL-Fogel

The following data represent coarse particulate organic matter (CPOM storage) within 14 study reaches in the Gordon Gulch watershed, CO, USA. CPOM storage is presented in terms of volume (total volume of CPOM within a given reach) weighted CPOM volume (CPOM volume / channel area within a given reach) and CPOM accumulation frequency (# of accumulations per m stream length). CPOM storage was measured during early August through measurements of surface area, height, and porosity. Geomorphic and forest stand characteristics including slope, basal area, canopy density, d50, d84, bankfull width, pool area and pools per m stream length, wood frequency and wood load (volume/channel area), retentive feature frequency (# per m stream length), channel type (multi vs single threaded), and hydrologic regime (wet vs dry reaches) were measured during CPOM storage sampling.

Meta-FieldLog-GG-LF-Storage_Accumulation_LVL-Fogel

The following data represent coarse particulate organic matter (CPOM storage) within 14 study reaches in the Gordon Gulch watershed, CO, USA. Data are presented for each CPOM accumulation measured within the 14 study reaches. Surface area and height of accumulations were measured using a tape measure in the field, whereas porosity of each accumulation was visually estimated. The trapping mechanism responsible for storing each CPOM accumulation was noted, as was the composition of each CPOM accumulation.

Meta-FieldLog-GG-CPOM-Flux

This dataset presents CPOM flux during the summer 2022 field season at Gordon Gulch within two study reaches. Data are presented for the upstream and downstream ends of each reach in order to test for influences of within-a-reach geomorphic context on CPOM flux. Bunte bedload traps were deployed periodically at the upstream and downstream ends of each study reach during the summer. CPOM collected in the traps was dried and weighed and used with sampling duration to estimate CPOM flux.

FIELD SITE: COMO CREEK
Meta-FieldLog-CC-CPOM-Flux

This dataset presents CPOM flux during the summer 2022 field season at Como Creek within three study reaches. Data are presented for the downstream ends of each reach. Bunte bedload traps were deployed periodically at the downstream ends of each study reach during the summer. CPOM collected in the traps was dried and weighed and used with sampling duration to estimate CPOM flux.
