Effects of grid resolution on regional modelled groundwater salinity and salt fluxes to surface water J. Hydrol. (IF 5.9) Pub Date : 2024-09-01 Ignacio Farías, Gualbert H.P. Oude Essink, Perry G.B. de Louw, Marc F.P. Bierkens
Coastal fresh groundwaters face growing threats from rising withdrawals and climate change, with salinization of surface and groundwater as notable impacts. Recent developments in parallel variable-density modelling enable studying these threats at unexplored resolutions and extents. To improve the understanding of ground- and surface water salinization processes, we designed an experiment to measure

Analytical model for two-dimensional contaminant transport in a cut-off wall and aquitard system J. Hydrol. (IF 5.9) Pub Date : 2024-08-31 Haijian Xie, Ao Wang, Yanghui Shi, Huaxiang Yan
The cut-off wall is an effective countermeasure to prevent contaminant transport from a contaminated site. However, the aquitard beneath the cut-off wall may serve as a preferential path, leading to an earlier breakthrough of contaminants in the cut-off wall system. In this study, we present a 2-D analytical model for characterizing the contaminant transport in the cut-off wall and aquitard system

Dynamics of the risk of algal blooms induced by surface water temperature in an alpine eutrophic lake under climate warming: Insights from Lake Dianchi J. Hydrol. (IF 5.9) Pub Date : 2024-08-31 Jiabin Peng, Junxu Chen, Shiyin Liu, Tie Liu, Fuying Deng, Yunjiang Fan, Philippe De Maeyer
Climate change-induced higher water temperature is increasing the risk of algal blooms (ABs) in eutrophic water bodies. However, it is not well known how and to what extent warming affects ABs risk. In this work, with simple data input (satellite product, lake surface observation, and climate) and method structure (ensemble learning, statistical downscaling, and hierarchical clustering), a systematic
