Module flow_accumulation

This modules uses the calculated ice surface elevation, together with basal topography, to compute the hydraulic potential and hydraulic head and the associated flow accumulation area (Cohen et al., 2023)¹. For the later, we use the simple subglacial hydrology of the enthalpy module.

This module depends on the pyshed library.

Parameters

Default configuration file (flow_accumulation.yaml):

flow_accumulation:
  update_freq: 100.0

Description of the parameters:

Name	Description	Default value	Units
update_freq	Frequency at which to update the flow accumulation.	100.0	y
