Design solution: Riverine heat processes
Date last modified: 30 Jun 2019
Contributors: Hongyi Li, Ruby Leung
This is a completely new capacity added into E3SM/MOSART. All the heat processes are described in a physically-based way. The advective heat fluxes are estimated based on the advective water fluxes including the surface and subsurface runoff from hillslopes into the sub-network channel, from sub-network channel to main channel, and between upstrean/downstream main channels. The temperature of surface runoff is assumed to be equal to the average soil temperature (simulated by ELM) over the top 10cm soil layers. The temperature of subsurface runoff is assumed to be equal to the average soil temperature of those soil layers below the ground water table (simulated by ELM). The temperature of sub-network and main channel water is estimated based on the heat balance, including long-wave and short-wave solar radiation, sensible heat, latent heat and advective heat fluxes etc.

Verification is performed by checking the fields that are passed from ELM and EAM to MOSART through the flux coupler. MOSART-heat has been tested on Compy and passed the E3SM_developer tests.
Planned Validation Testing

Validation is performed by comparing the MOSART simulated stream temperature with observations from multiple river gauges.
