Decline in Iran's groundwater recharge. [PDF]

Nat Commun, 2023
Abstract Groundwater recharge feeds aquifers supplying fresh water to a population over 80 million in Iran – a global hotspot for groundwater depletion. Using a rich database comprising abstractions from about one million groundwater wells, springs and qanats, from 2002 to 2017, here we show a significant decline of around -3.8 mm/yr in the ...

Evaluation of drought impact on groundwater recharge rate using SWAT and Hydrus models on an agricultural island in western Japan [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Clarifying the variations of groundwater recharge response to a changing non-stationary hydrological process is important for efficiently managing groundwater resources, particularly in regions with limited precipitation that face the risk of water ...

Groundwater and baseflow drought responses to synthetic recharge stress tests [PDF]

Hydrology and Earth System Sciences, 2021
Groundwater is the main source of freshwater and maintains streamflow during drought. Potential future groundwater and baseflow drought hazards depend on the systems' sensitivity to altered recharge conditions.

Assessing the role of groundwater recharge from tanks in crystalline bedrock aquifers in Karnataka, India, using hydrochemical tracers

Journal of Hydrology X, 2022
The majority of India’s rural drinking water supply is sourced from groundwater, which also plays a critical role in irrigated agriculture, supporting the livelihoods of millions of users. However, recent high abstractions are threatening the sustainable

Impacts of climate change on Swiss alluvial aquifers – A quantitative forecast focused on natural and artificial groundwater recharge by surface water infiltration

Journal of Hydrology X, 2022
The sensitivity of future groundwater recharge and temperature development was investigated for three alluvial aquifers in the urban agglomeration of the city of Basel, Switzerland. For selected climate projections groundwater recharge and the associated
