Use in-/outflow on top/bottom to apply recharge (due to precipitation) to lake?

Hi,

when using in-/outflow on top/bottom to apply recharge (due to precipitation) to groundwater, what would happen if you apply the recharge to lake surface (constant head BC)?  Will it have any impact on the solution? Theoretically the recharge due to precipitation to the area covered by lake should be zero, right?

Thanks in advance,

Quinn

The recharge will still occur - and would offset the flux associated with the specified head BC.  The result should be the same as not applying recharge to the lake, but the reporting of flow budgets will be different.
