Abstract A three‐dimensional variably saturated flow model was developed for assessing future global water resources and parameterized groundwater pumping. We applied this to an actual watershed verify its validity as Earth System Model. For applicability, the parameterization method multi‐layered pumping verified through comparison with observations MODFLOW results. The proposed in study is ap...

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...

Environmental modelling workflows are often tedious due to heterogeneity of data sources, types and formats. This paper discusses how a software framework based on Open Geospatial Consortium (OGC) standards may facilitate the workflow steps and improve their flexibility by supporting data access, processing, and decision-making. The software framework is designed based on OGC standards, which c...

In the present work WRF model is used to generate meteorological fields for the HYSPLIT dispersion model. Sensitivity and validation of the WRF model, is conducted by utilizing different combinations of physical parameterization schemes. For this purpose, eight different configurations are examined. Assessment of the predictions of the WRF model is carried out by computing the statistical param...
