hydromodpy.solver.modflow_common.recharge_evt_routing

Shared negative-recharge to EVT routing for MODFLOW 6 and MODFLOW-NWT.

A negative net recharge (precipitation minus evapotranspiration) is a climatic deficit. It is clipped out of RCH and routed to an EVT sink. On a steady spin-up period the forcing must be the long-term time mean, so both the positive recharge and the routed deficit carry the per-cell mean over all periods. Transient periods keep their own positive/negative split. Keying on the steady flag (not kper == 0) makes a transient first period keep its own split.

Functions

route_negative_recharge_to_evt(...)

Split per-period recharge into clipped RCH (>=0) and routed EVT deficit (>=0).
