default_watershed_control: Default control parameters for watershed processes

In medfateland: Mediterranean Landscape Simulation

Default control parameters for watershed processes

Description

Defines default control parameters for watershed processes

Usage

default_watershed_control(watershed_model = "tetis")

Arguments

watershed_model

Hydrological model for watershed processes. Only "tetis" or "serghei" are accepted.

Value

A list with the following items:

• watershed_model: A string with the watershed model.

• weather_aggregation_factor [= 1]: An integer specifying the spatial aggregation for interpolated weather.

• tetis_parameters: A list of TETIS parameters with the following elements:

  • R_localflow [= 1.0]: Correction factor for soil hydraulic saturated conductivity (local vertical flows).

  • R_interflow [= 50.0]: Correction factor for soil hydraulic saturated conductivity (subsurface flow between grid cells).

  • R_baseflow [= 5.0]: Correction factor for bedrock hydraulic conductivity (groundwaterflow between grid cells).

  • n_interflow [= 1.0]: Exponent for the determination of interflow.

  • n_baseflow [= 1.0]: Exponent for the determination of baseflow.

  • num_daily_substeps [= 4]: Number of daily sub-steps for interflow calculations.

  • channel_flow_speed [= 1]: Average flow speed in the channel (in m/s).

  • subwatersheds [= FALSE]: A boolean flag to define watershed subunits.

  • max_overlap [= 0.2]: Maximum proportion of overlapping cells for watershed subunits to be considered independent. Lower values will normally produce larger subunits.

  • rock_max_infiltration [= 10]: Maximum infiltration rate (mm·day-1) for rock cells.

  • deep_aquifer_loss [= 0]: Daily loss rate from watershed aquifer towards a deeper aquifer not connected to outlets (mm·day-1).

• serghei_parameters: A list of SERGHEI parameters with the following elements:

  • input_dir [= ""]: Path to SERGHEI input files.

  • output_dir [= ""]: Path to SERGHEI output files.

  • force_equal_layer_widths [= FALSE]: A boolean flag to force equal layer widths (taken from the first soil element) in all soils.
