[1] This paper investigates whether particle ensembles in a fractured rock domain may be adequately modeled as an operator-stable plume. If this statistical model applies to transport in fractured media, then an ensemble plume in a fractured rock domain may be modeled using the novel Fokker-Planck evolution equation of the operator-stable plume. These plumes (which include the classical multi-G...

Low permeability zones (LPZs) are major sources of groundwater contamination after active remediation to remove pollutants in adjacent high (HPZs). Slow back diffusion from LPZs HPZs can extend management polluted sites by decades. Numerical models often used simulate diffusion, estimate cleanup times, and develop site strategies. Sharp concentration gradients present at the interface between L...

Abstract Landfill requires a systematic monitoring of its impact on groundwater and surface waters. The paper presents the modeling pollution migration for cases when leachate penetrates aquifer layer. For this purpose, conceptual hydrodynamic model was developed in program Visual ModFlow Pro, which is spatial two-layer model. Chloride ion used as an indicator defining rate migration. results c...

The standard formulation of a block-centered finite-difference model, such as MODFLOW, uses the center of the cell as the location of a cell node. Simulations of a dynamic water table can be improved if the node of a cell containing the water table is located at the water table rather than at the center of the cell. The LPF package of MOD-FLOW-2000 was changed to position a cell's node at the w...

Multiaquifer wells, i.e. wells that are open across more than one aquifer, can have a profound effect on the hydraulics of the groundwater system. They change the physical system by acting as very permeable tubes that establish direct hydraulic links between nonadjacent strata. The inclusion of a multiaquifer well in a numerical model of groundwater flow also changes the governing equations. Se...

Pemahaman komprehensif interaksi hidrologi–hidrogeologi dapat dilakukan dengan pendekatan pemodelan numerik. Salah satu perangkat coupled model hidrologi-hidrogeologi adalah SWAT-MODFLOW. Penelitian ini ditujukan untuk mengevaluasi kemampuan SWAT-MODFLOW dan memahami hidrologi hidrogeologi studi kasus wilayah Daerah Aliran Sungai Cisangkuy, Kabupaten Bandung. Hasil dari simulasi memperlihatkan ...
