Groundwater from the (largely unconfined) chalk aquifer constitutes a major water resource. The unsaturated zone plays a crucial role in the hydrological cycle, determining the timing and magnitude of recharge, and the transport and fate of nutrients. However, despite over 30 years of study our understanding of this system is incomplete.
The objectives of this research were to investigate the aquifer characteristics of the chalk and to clarify the physical processes controlling the movement of water in the unsaturated zone
