Short summary
Short summary
Groundwater is an essential resource affected by climate conditions and anthropogenic activities. Estimations of groundwater recharge under current and future climate conditions require long-term climate records that are scarce. Different methods to synthesize climate data, based on observations, are used to estimate groundwater recharge. In terms of groundwater recharge estimation, the best synthesis method is based on the daily statistics corrected to match the observed monthly statistics.

This study presents a novel approach for in-situ large-scale remediation of contaminated unsaturated zone and groundwater. Flow and transport models were calibrated against continuously monitored data, enabling evaluation of the required conditions for optimal contaminate removal. The results enabled realistic data-based predictions of the time frame that is required to attain full contaminant removal through efficient and low-cost in-situ treatment technique.

Short summary
The quality control and optimization of soil aquifer treatment (SAT) performance is challenging due to the multiple factors and costs involved. We installed in situ subsurface monitoring sensors that provided continuous high-resolution monitoring of the biochemical and physical conditions of an active SAT system. Data analysis facilitated the determination of the optimal drying and wetting stages, which are critical for suitable SAT management.

Short summary
Future climate projections suggest that climate change will impact groundwater recharge, with its exact effects being uncertain due to incomplete understanding of rainfall, evapotranspiration, and recharge relations. We studied the effects of changes in the average, spread, and frequency of extreme events of rainfall and evapotranspiration on groundwater recharge. We found that increasing or decreasing the potential evaporation has the most dominant effect on groundwater recharge.
Future climate projections suggest that climate change will impact groundwater recharge, with...
