# rcv\_ob

The receiving object can be specified by entering "cha" for channels, "res" for reservoirs, or "aqu" for aquifers. If non of these three options is entered, SWAT+ assumes that the water is transferred to an object outside the modeled watershed and thus lost from the system. By entering a name in this column, the user can make sure that the receiving object is included in the water allocation output file.
