I have found negative recharge in some basins. What does it mean?

For negative recharge, the sites represent areas where no recharge takes place or where the net movement of water in the unsaturated zone is vertically upward. This may be a result of several factors such as the local soil composition and the évapotranspiration rate. Also the site may be in a groundwater discharge zone on a microscale and hence the flow may have a vertical component directed upwards.

With my best regards

The basin has an area of 900 km² and the data river flow analised represents this area. I guess this negative recharge is related to water abstraction from river to irrigation in dry periods, but i am looking for some correlated examples in literature.
