Natural Recharge

The recharge represents inflow to the groundwater source -- inflows that are not explicitly modeled in WEAP (e.g., return flows). You may specify the inflow using the Water Year Method, the Read from File Method, or with an expression. See Specifying Inflow for details. Note: do not use this variable if you are linking WEAP to MODFLOW.  Natural recharge is allowed to be less than zero, for example, to model lateral outflow from an aquifer to another aquifer outside the system.  To model flow from one groundwater node to another, both of which are in the system, you can use the Groundwater to Groundwater Flow variable.  If you do, make sure not to double count those flows in the Natural Recharge.
