interflow

Source: R/RcppExports.R
inteflow.Rd

In hydrological modeling, interflow refers to the movement of water that is transported horizontally through the soil or aquifer. Like baseflow, the impact of other RUs (response units) on the route to the river will be ignored.

It can be calculated by the water in the soil layer \(W_{soil}\), which can also be tread as the part of the \(W_{soil}\).

So we can give the function from:

\[F_{itfl} = f_{inteflow}(D_{grnd}, D_{soil})\]

to:

\[F_{itfl} = f_{inteflow}(W_{soil}, C_{soil}, ...) = k^* W_{soil}\] \[F_{itfl} \leq W_{soil}\]

where

  • \(F_{itfl}\) is soil_inteflow_mm

  • \(W_{soil}\) is water_soil_mm

  • \(C_{soil}\) is capacity_soil_mm

  • \(k^*\) is estimated ratio

The output density distribution from 8 methods:

Value

inteflow_mm (mm/m2)

_GR4Jfix (Perrin et al. 2003) :

\[k^* = 1 - \left[ 1 + \left(k \frac{W_{soil}}{C_{soil}} \right)^\gamma \right]^{-1/\gamma}\] where

  • \(k\) is param_inteflow_grf_k

  • \(\gamma\) is param_baseflow_grf_gamma

_MaxPow:

\[F_{itfl} = M_{itfl} \left(\frac{W_{soil}}{C_{soil}} \right)^\gamma\] where

  • \(M_{itfl}\) is soil_potentialInteflow_mm

  • \(\gamma\) is param_inteflow_map_gamma

_ThreshPow

based on the _MaxPow and add the one threshold \(\phi_b\): \[F_{itfl} = 0, \quad \frac{W_{soil}}{C_{soil}}

  • \(\phi_b\) is param_inteflow_thp_thresh

  • \(\gamma\) is param_inteflow_thp_gamma

_Arno (Franchini and Pacciani 1991; Liang et al. 1994)

has also in two cases divided by a threshold water content \(\phi_b\): (This method is actually not the original method, but an analogy with inteflow_Arno) \[F_{itfl} = k M_{itfl} \frac{W_{soil}}{C_{soil}}, \quad \frac{W_{soil}}{C_{soil}}

  • \(\phi_b\) is param_inteflow_arn_thresh

  • \(k\) is param_inteflow_arn_k

_BevenWood (Beven and Wood 1983; Beven et al. 1995) :

\[k = \frac{W_{soil}}{C_{soil} - W_{soil}} \quad {\rm and} \quad k \leq 1\] \[F_{itfl} = k M_{itfl}\] where

  • \(k_{fc}\) is soil_fieldCapacityPerc_1

  • \(\gamma\) is param_inteflow_sup_gamma

_SupplyPow0:

\[F_{base} = k(W_{grnd})^\gamma\] where

  • \(k\) is param_inteflow_sup_k

  • \(\gamma\) is param_inteflow_sup_gamma

_SupplyPow:

\[k^* = k \left(\frac{W_{soil}}{C_{soil}} \right)^\gamma\] where

  • \(k\) is param_inteflow_sup_k

  • \(\gamma\) is param_inteflow_sup_gamma
