Shown below are three different predictions of the steady-state normal wetness index, defined in equation 4.1 in Chapter 4 of the User Guide and in O'Loughlin (1986). A value of 1 or higher denotes that the element is saturated, ie. the upslope flux of drainage exceeds the capacity of the element to transmit that flux.
In each case it has been assumed that the soil transmissivity is 1 m/d. What is being varied between simulations is the net lateral drainage flux term (q). In simulation 1 q is set at 0.1 mm/d, whereas in simulations 2 and 3 q is set to 0.3 and 0.5 mm/d, respectively.
The percentage of catchment saturated increases from 5.2% for simulation 1, to 11.6% for simulation 2, and 16.0% for simulation 3.
