Description
-----------
n_HRU >>> Number of hydrological response units (HRU) [-]
HRUs >>> Description of hydrological response units
Vwcaps >>> Water storage capacities of HRUs
ks >>> Residence time parameters for HRUs
shares >>> Relative share of HRUs to total area
Asnow >>> Albedos for HRUs when covered with snow
Anosnow >>> Albedos for HRUs when not covered with snow
Ele >>> (Mean) catchment elevation [m a.s.l.]
area >>> Total catchment area [km2]
Tsa >>> Temperature threshold for snow accumulation [degreeC]
Tsm >>> Temperature threshold for snow melt [degreeC]
m >>> Melt rate factor [-]
alphaET >>> Evaptranspiration parameter [-]
LStrig >>> Landslide triggering mechanism e['thermal', 'rainfall', 'random']
Tpr >>> Precipitation threshold for rainfall-landslides to be triggered [mm]
Tsd >>> Snow-depth threhsold for landslides to be triggered [mm SWE]
Tfreeze >>> Temperature threshold for landslide triggered by freezing [degreeC]
qdf >>> Critical discharge for debris flows to be triggered [mm]
smax >>> max volumetric ratio of sediment to water [mm/mm], typically <= 0.8
smax_nodf >>> max possible volumetric sediment concentration for bedload transport (for sub-critical flows) [mm/mm], typically <= 0.4
a >>> Scaling parameter for bedload transport in sub-critical flow conditions, determined automatically
b >>> Shape parameter for bedload transport in sub-critical flow conditions, typically =1.5
Qmin_nodf >>> min discharge for bedload transport initiation, determined automatically
rhc >>> Deposition rate from hillslope to channel, i.e. fraction of landslide going into hillslope storage and 1-rhc is the fraction going into the channel storage.
minDF >>> min (measured) debris-flow volume (water + sediment) [m3]
rho_b >>> bedrock density [kg/m3]
rho_dry >>> density of stored sediments, dry unit weight (sediment and air) [kg/m3], e.g. 2000 means porosity of 23%
rho_bulk >>> density of debris flows (sediment and water) [kg/m3], i.e. porosity of 38%
shcap >>> hypothetical threshold [m3] for collapse of hillslope storage, considered density is 'rho_dry'
ls_xmin >>> Minimum landslide volume from the power-law tail
ls_alpha >>> Power law scaling exponent in landslide distribution
ls_cutoff >>> The maximum potential landslide volume (m^3)
M >>> number of stochastic simulations for hillslope module
