Assessing the impacts of different crop rotations on groundwater level using MODFLOW in a dry, Barind area of Bangladesh

open access: yesWater Policy, 2023
The lowering of the groundwater table caused by increased groundwater use in the dry, Barind region has prompted sustainability concerns. In this study, water-table (WT) scenarios were simulated by the MODFLOW model under different crop rotations in ...

بررسی پایداری منابع آب در حوضه زاینده رود با استفاده از شاخص‌های پایداری و مدل GMS (مطالعه موردی: آب خوان نجف آباد در حوضه زاینده رود) [PDF]

open access: yesعلوم و مهندسی آبیاری, 2020
امروزه استفاده بی­رویه از منابع آب سطحی و زیرزمینی این منابع را در معرض خطر قرار داده و از این رو وجود یک برنامه جامع مدیریتی در جهت بهبود بازخوردها و حفظ تعادل و پایداری منابع آب ضروری است.

Incorporating Electrostatic Coupling Effects into Multispecies Solute Transport Simulations with MODFLOW

open access: yesGroundwater, EarlyView.
Abstract Solute transport simulators aiming to accurately describe the transport of charged chemical species in porous media need to account for electrostatic coupling effects. Each ion in pore water possesses a specific electric charge and molecular diffusion coefficient, properties that determine their mobility and the overall charge balance of ...

Impacts of boundary conditions and parameter heterogeneity on the simulation and prediction of water inflow in coal mines

open access: yesMeitian dizhi yu kantan
BackgroundAccurate prediction of water inflow in coal mines is essential for ensuring safe mining operations. Three-dimensional (3D) groundwater numerical models can be used to characterize hydrogeological conditions in mining areas and simulate the ...

Towards Holistic Braided River Management: The Interface of Geomorphology, Hydrology, Ecology and Economics

open access: yesRiver Research and Applications, Volume 42, Issue 2, Page 415-431, February 2026.
ABSTRACT Braided rivers are some of the most dynamic and complex river systems in the world. They provide unique habitat to rare species, supply natural resources, and act as a source of groundwater recharge. However, they can also pose significant flooding and erosion hazards. Current management of braided rivers in Aotearoa New Zealand faces a strong

Groundwater Age and Nonpoint Source Pollutant Mixing in Alluvial Aquifer Wells: Comparing the Role of Diffusion, Dispersion, Aquifer Heterogeneity, and Well Screen Length

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Understanding the mixing of groundwater age and of nonpoint source (NPS) pollutants in water samples is crucial for interpreting age tracer and NPS pollutant data from production wells. Traditionally, diffusion and mechanical dispersion have been key mixing processes embedded in physical models for simulating and interpreting age tracer and ...

Evaluating Simulated Groundwater Contributions to Streamflow in a Data‐Scarce, Semi‐Arid Catchment in South Africa

open access: yesHydrological Processes, Volume 40, Issue 1, January 2026.
Calibration procedure selection should be carefully considered in data‐scarce circumstances, as good model efficiency does not necessarily guarantee a realistic representation of hydrological processes. Stable isotopes proved effective in validating model results and detecting shortcomings in the J2000 model caused by sparse hydroclimatic data and the ...
