| - | There are two model options for processes deep below ground; regional groundwater flow and aquifers. The regional groundwater flow model simulates groundwater flow between subbasins, but no explicit storage of deep groundwater. The aquifer model simulates aquifer storage and delay before regional groundwater reaches the destination. | + | There are two model options for processes deep below ground; regional groundwater flow and aquifers. The regional groundwater flow model simulates groundwater flow between subbasins, but no explicit storage of deep groundwater. The aquifer model simulates aquifer storage and delay before regional groundwater reaches the destination. Another model option related to groundwater flow, although not classified as deep processes by HYPE is the option for recharge and discharge classes within a subbasin ([[start:hype_model_description:hype_land#recharge_-_discharge_model|read more here]]). |

| The outflow may be divided between several receiving subbasins (//retfrac//). The receiving subbasins may or may not be different from the subbasin recharging the aquifer. The specified fraction of outflow is added to the inflow to the main river of these subbasins. | The outflow may be divided between several receiving subbasins (//retfrac//).

| + | It is possible to simulate that (part of) the aquifer's outflow leads to outside of the modelled domain (sum of retfrac less than 1). It is possible to simulate addition of water (from aquifers) from outside the model domain to the model as aquifer recharge by upscaling the recharge calculated for an aquifer in the model set-up (sum of retfrac larger than one). | ||
