Groundwater from unconfined chalk aquifers constitutes a major water resource in the UK. The unsaturated zone in such systems plays a crucial role in the hydrological cycle, determining the timing and magnitude of recharge, and the transport and fate of nutrients. However, despite more than three decades of study, our physical understanding of this system is incomplete. In this research, state ...

Climate change is exacerbating water shortages in upstream basins the Korean peninsula that lack agricultural supply systems. The basin investigated this study requires an extra 208 m3·d?1 of during May (the busiest month for agriculture). purpose was to assess a hybrid-artificial recharge and circulation system, which composed hybrid-recharge source re-infiltration pumped field, estimate yield...

RFID tags are used for different purposes. One of the major problems to be addressed, particularly for monitoring purposes, is their limited power autonomy. Tags must perform different tasks with limited power consumption and their batteries capacities are often too low, even if low power consumption techniques are implemented. In these operational situations tags should be kept in operation fo...
