SetSoil

Observations

• none

Variables

• run_ID () - run identification.

Parameters

• basin_area (km^2) - basin area.
• hru area (km^2) - HRU area.
• hru_lat (°) - latitude.
• hru_elev (m) - altitude.
• hru_GSL (°) - ground slope.
• hru_ASL (°) - aspect.
• basin_name - text string.
• hru_names - text strings.
• RUN_ID - integer number. Used to uniquely identify "CRHM_output" log files when RUN_ID is positive.
• RUN_START (d) - run start day. Only used on batch execution.
• RUN_END (d) - run end day. Only used on batch execution.
• INIT_STATE - initial state file (Automation).
• Vol_h2o_content () - fractional volumetric water content.
• soil_Depth_rechr (m) - recharge depth.
• soil_Depth (m) - soil column depth.
• soil_type_rechr () - recharge layer soil type. 0 - 12, water/sand/loamsand/sandloam/loam/siltloam/sasclloam/clayloam/siclloam/sandclay/siltclay/clay/pavement.
• soil_type () - soil column. 0 - 12, water/sand/loamsand/sandloam/loam/siltloam/sasclloam/clayloam/siclloam/sandclay/siltclay/clay/pavement.

    The following parameters are set by this module from the above information and need not be set.

• soil_rechr_max = soil_Depth_rechr*SetSoilproperties[soiltype][field capacity - wilt].
• soil_rechr_init = soil_Depth_rechr*(Vol_h2o_content*SetSoilproperties[soiltype_rechr][field] - SetSoilproperties[soiltype_rechr][wilt]).
• soil_moist_max = soil_Depth*SetSoilproperties[soiltype][field capacity - wilt].
• soil_moist_init = soil_Depth*(Vol_h2o_content*SetSoilproperties[soiltype][field] - SetSoilproperties[soiltype][wilt]).
• soil_rechr_init is limited to the range >= 0 and <= soil_rechr_max.
• soil_moist_init is limited to the range >= 0 and <= soil_moist_max.
• soil_rechr_init cannot be > soil_moist_init.
• When the two soil layers are of different types the values are only approximate.

Variable Inputs

• none

Notes

1. This module only executes once as an initialization routine before the model execution..
