Towards a Model of  Carbon Mobilization, Advection, and Reaction in the Amazon River

  • As the LBA “Community,” we have a set of “linked” questions (possibly, with a common solution):

  • What are hydrologic flow paths and magnitudes?

  • How are CO2 and OM mobilized from the land surface to and through fluvial systems?

  • What controls transformations of N from land to streams?

  • HOW CAN WE PULL IT TOGETHER?

  • Uses measurable and mechanistically meaningful pools

    • CPOM

    • FPOM

    • DOM

  • Capacity to model processes

    • Mineralization (OCCO2)

    • Degradation (OCfastOCslow)

    • Sorption (DOC  FPOC)

SEDIMENT TRANSPORT MODEL

Upland Source Element

(Production > | Storage|, physically &

chemically converts rock to sediment)

Down-zone transport

Colluvial Buffer Element

( |S| > P, controls sediment delivery ratio

by regulating delivery to channel network)

Down-zone transport

River Network Element

(P  0, specifically for in-channel routing & evolution of wash load and bed load, and calculating transfer to FP and channel bed)

Downstream transport

Floodplain Storage

Channel Bed Storage

(Element significance decreases DS)

(Element significance increases DS)

Floodplain Lakes
