interception
1. The capture of rain water by vegetation from which the water evaporates and is thus prevented from reaching the water-table and contributing to surface run-off, soil moisture, or groundwater recharge.

2. The abstraction of groundwater part of the way along its flow path, where otherwise the water might be lost (e.g. as coastal spring discharges).
