• Decadal simulation of winter deep percolation driven by snowmelt and precipitation using HYDRUS-1D (2026) · Frontiers in Environmental Science · doi

  This study is limited to winter season rainfall and snowmelt, season crop excluding irrigation, and vegetation cover. evapotranspiration, Therefore, incorporate multimodal should comparison across soil types, growing season processes, and broader validation to strengthen understanding of bottom flux the root zone and groundwater potential recharge. from HYDRUS modeling provides an understanding of fluxes under diverse locations, soils, and climates, which supports informed decision-making for water management in agricultural fields. Certain management practices such as precision irrigation, soil amendments, organic matter, soil cover, terracing, and cover cropping enhance water infiltration and sustainable groundwater recharge, which needs to be explored to improve understanding of the water balance and groundwater potential recharge in agricultural systems. These findings highlight the need to account for winter season hydrological processes in groundwater assessment, especially in coarse-textured soils. Integration of snowmelt-driven DP into agricultural water management can improve potential recharge estimation, support sustainable irrigation management, and enhance resilience to cope with increasing winter climate variability.

• Impact of changing rainfall patterns on groundwater recharge in semi-arid dune landscapes (2026) · Hydrogeology Journal · doi

  There is a pronounced scarcity of long-term field data quantifying the interaction between rainfall intensity and vegetation cover. Prior work has not adequately addressed the impact of vegetation cover on groundwater recharge.
