Overland flow

For kinematic wave routing and local inertial routing 1D river and 2D overland flow. For the local inertial routing 1D river and 2D overland flow, water balance errors are computed for each land cell (total storage) considering both river and overland flow.

Standard Name	Description	Unit
subsurface_water_mass_balance_error__volume_flow_rate	Subsurface flow water mass balance error	m³ day⁻¹
subsurface_water_mass_balance_relative_error__number	Subsurface flow water mass balance relative error	-
