DWCZ - CO - Gordon Gulch-Como Creek -- CPOM, Storage Accumulation & Reach -- ( CC-GG-CPOM-Flux-Fogel)4/28/2022-8/11/22

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.

本数据集共包含4组数据：
### 野外站点：戈登谷（Gordon Gulch）
1. Meta-FieldLog-GG-LF-StorageReachLVL-Fogel
本数据集收录了美国科罗拉多州戈登谷流域14个研究河段内的粗颗粒有机质储存数据。CPOM储存量以体积（指定河段内CPOM总体积）、加权CPOM体积（指定河段内CPOM体积/河道面积）以及CPOM堆积频率（每米溪流长度的堆积物数量）三种指标进行表征。CPOM储存量于8月初通过测量表面积、高度与孔隙率完成测定。同期还开展了地貌与林分特征的测定工作，涵盖坡度、断面积、冠层密度、d50、d84、平滩宽度、潭面积及每米溪流长度的潭数量、木质碎屑频率与木质荷载（体积/河道面积）、滞留特征频率（每米溪流长度的数量）、河道类型（多股与单股河道）以及水文状态（湿段与干段）。

2. Meta-FieldLog-GG-LF-Storage_Accumulation_LVL-Fogel
本数据集同样针对戈登谷流域14个研究河段内的粗颗粒有机质储存，数据对应14个河段中每一处被实测的CPOM堆积物。野外采用卷尺测量堆积物的表面积与高度，通过目视估算单处堆积物的孔隙率。研究记录了负责滞留该CPOM堆积物的捕获机制，以及每处CPOM堆积物的组成成分。

3. Meta-FieldLog-GG-CPOM-Flux
本数据集呈现了2022年夏季野外调查期间，戈登谷两个研究河段内的CPOM输运通量数据。数据分别取自每个河段的上游与下游端，用于检验河段内地貌背景对CPOM输运通量的影响。夏季期间，研究团队在每个研究河段的上下游端定期布设邦特（Bunte）推移质采样器。采集得到的CPOM经干燥称重后，结合采样时长估算CPOM输运通量。

### 野外站点：科莫溪（Como Creek）
Meta-FieldLog-CC-CPOM-Flux
本数据集呈现了2022年夏季野外调查期间，科莫溪三个研究河段内的CPOM输运通量数据。数据取自每个河段的下游端。夏季期间，研究团队在每个研究河段的下游端定期布设邦特推移质采样器。采集得到的CPOM经干燥称重后，结合采样时长估算CPOM输运通量。
