The Geology of Aquitards in Alluvial Aquifers: A Predictive Approach Based on Facies Models

Groundwater, Volume 64, Issue 1, Page 30-40, January/February 2026.
We review facies models for alluvial aquifers and demonstrate how they can be used to predict aquifer and aquitard continuity in three dimensions. We provide case studies illustrating how facies models can be used to improve groundwater investigation and remediation outcomes.

Modelling the Effects of Wetland Restoration on Coastal Hydrology: A Case Study of Elkhorn Slough Watershed, California

Hydrological Processes, Volume 39, Issue 12, December 2025.
This study indicates that Hester Marsh, a restored site successfully maintains surface elevation, resulting in reduced surface inundation. The low‐lying Yampah Marsh, a reference site, is likely to be inundated due to future sea level rise (SLR) when the highest tides arrive, while a higher percentage of Hester Marsh would retain marsh vegetation in ...

Application of MODFLOW and MT3DMS Models to Evaluate Groundwater Quantity and Quality in Northern Iran [PDF]

Journal of Hydraulic and Water Engineering
In recent decades, climate change and drought have led to an increase in groundwater use in the world. In Iran, due to being in the global dry belt and also the impact of climate change, reduced rainfall and surface water, excessive use of groundwater ...

3-D land subsidence simulation using the NDIS package for MODFLOW [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
The standard subsidence package for MODFLOW, MODFLOW-SUB simulates aquifer-system compaction and subsidence assuming that only 1-D-vertical displacement of the aquifer system occurs in response to applied stresses such as drawdowns accompanying ...

Effects of Subsurface Water Infiltration Systems on Groundwater Table Dynamics in Drained Peat Soils

Hydrological Processes, Volume 39, Issue 12, December 2025.
The effects of subsurface water infiltration systems on groundwater table dynamics are captured in six hydrologically relevant parameters for five sites. Water infiltration systems, if applied correctly, reduce the amplitude in groundwater table fluctuations, most notably by raising water tables during dry periods.
