Title: Mosart Sediment
Requirements and Design
E3SM BGC Group
Date:
Summary
The riverine suspended sediment capacity is added to the E3SM BGC system. The new code simulates the suspended sediment fluxes from hillslopes into small rivers then through the river systems to the coasts. It also simulates the riverine sediment transport, erosion and deposition processes as function of hydraulic conditions simulated by MOSART-water. The success of the code would be satisfactory performance evaluated against the observed sediment discharges over multiple river gauges in different river systems.
Requirements
Requirement: Implementing riverine sediment process description on top of ELM soil erosion (Zeli Tan), MOSART-water and water management.

MOSART-sediment has been developed and tested offline in a data-land mode based on the apcraig/mosart/add-inundation branch which was based off the E3SM v1 master branch a while ago. I will create a new MOSART-sediment branch based on the merger of two new branches tizhou/mosart/add-wm-inundation and tanzeli/lnd/elm-erosion-master. The former is based off the latest E3SM v2 master branch and includes the newest code of MOSART-water and water management. The latter is also based off the latest E3SM v2 master branch and includes the newest code of soil erosion.
Requirement: Validating MOSART-sediment

MOSART-sediment simulations will be validated against the observed sediment data from multiple USGS gauges.

For each requirement, there is a design solution that is intended to meet that requirement. Design solutions can include detailed technical discussions of PDEs, algorithms, solvers and similar, as well as technical discussion of performance issues. In general, this section should steer away from a detailed discussion of low-level software issues such as variable declarations, interfaces and sequencing.
