The role of gravel channel beds on the particle size and organic matter selectivity of transported fine-grained sediment: implications for sediment fingerprinting and biogeochemical flux research

Purpose The preferential erosion, delivery, and transport of sediment within a drainage basin can result in downstream changes in both particle size and organic matter content. The physical and biological properties of transported and deposited sediment are important considerations in many sediment...

Description
Summary:Purpose The preferential erosion, delivery, and transport of sediment within a drainage basin can result in downstream changes in both particle size and organic matter content. The physical and biological properties of transported and deposited sediment are important considerations in many sediment management and investigative tools, including sediment fingerprinting, and aid in the interpretation of sediment-associated nutrient and contaminant data. Materials and methods A recirculating flume (2 × 2 × 40 m) was used to assess the changes in particle size, organic matter content, and geochemical composition of fine-grained sediment (
