CZNet DWCZ - CO - Gordon Gulch & Como Creek - CPOM Storage, Accumulation & Flux (Fogel) - (2022)

OVERVIEW

Description/Abstract

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

Four datasets are included:

FIELD SITE: GORDON GULCH
Meta-FieldLog-GG-LF-StorageReachLVL-Fogel
Represents 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 CPOM volume within a given reach), weighted CPOM volume (CPOM volume/channel area), and CPOM accumulation frequency (# of accumulations per meter of stream length). Storage was measured in early August using measurements of surface area, height, and porosity. Geomorphic and forest stand characteristics (slope, basal area, canopy density, D50, D84, bankfull width, pool area, pool frequency, wood frequency, wood load, retentive-feature frequency, channel type, and hydrologic regime) were measured concurrently.

Meta-FieldLog-GG-LF-Storage_Accumulation_LVL-Fogel
Contains CPOM storage data measured at the accumulation scale within the same 14 reaches. Surface area and height of accumulations were measured in the field; porosity was visually estimated. The trapping mechanism and composition of each accumulation were also recorded.

Meta-FieldLog-GG-CPOM-Flux
Represents CPOM flux during the summer 2022 field season at two study reaches in Gordon Gulch. Data are presented for the upstream and downstream ends of each reach. Bunte bedload traps were deployed periodically, and CPOM collected in the traps was dried and weighed to estimate flux.

FIELD SITE: COMO CREEK
Meta-FieldLog-CC-CPOM-Flux
Represents CPOM flux during the summer 2022 field season at three study reaches in Como Creek. Data are presented for the downstream ends of each reach. Bunte bedload traps were deployed periodically, and CPOM collected in the traps was dried and weighed to estimate flux.
