Hi all,
I saw examples of coupling overland flow with Richards flow. The coupling method is to add the following statement in .st file:
#SOURCE_TERM
$PCS_TYPE
OVERLAND_FLOW
$PRIMARY_VARIABLE
HEAD
$GEO_TYPE
POLYLINE SURFACE
$DIS_TYPE_CONDITION
CONSTANT_NEUMANN 1
PCS RICHARDS_FLOW
PRESSURE1
2.75000e-02 1.e-3
#SOURCE_TERM
$PCS_TYPE
RICHARDS_FLOW
$PRIMARY_VARIABLE
PRESSURE1
$GEO_TYPE
POLYLINE SURFACE
$DIS_TYPE_CONDITION
CONSTANT_NEUMANN 1
PCS OVERLAND_FLOW
HEAD
2.75000e-02 1.e-3
I am not sure about the meaning of the parameters: 2.75000e-02 and 1.e-3. I would appreciate if you have any suggestions or clue on this.
Best,
Xuan
