The scale of CO2 injection into the subsurface required to address CO2 atmospheric concentrations is unprecedented. Multiple injection sites injecting into multiple formations will create a large excess pressure zone extending far beyond the limited volume where CO2 is present. In a closed system, additional mass is accommodated by the compressibility of system components, an increase in fluid ...

The City ofRostov the Great (Rostov) is one of the oldest cities in the Russian Federation. Many buildings need to be restored due to advanced degradation of the wooden and stone foundations. This degradation and other environmental problems are in large part caused by high groundwater levels, which are in turn directly associated with human activity over the years. Technical analyses were comp...

Measures of soil and water conservation (SWC) could affect the hydrological process. The impacts of typical measures on groundwater recharge, levels and flow were analyzed based on simulated rainfall experiments and a groundwater model. The three-dimensional finite-difference groundwater flow model (MODFLOW) was calibrated and verified for bare slope, grassland and straw mulching scenarios base...

Unmodified versions of common computer programs such as MODFLOW, MT3DMS, and SEAWAT that use Cartesian geometry can accurately simulate axially symmetric ground water flow and solute transport. Axisymmetric flow and transport are simulated by adjusting several input parameters to account for the increase in flow area with radial distance from the injection or extraction well. Logarithmic weight...

FRACK is a fractured media freeware flow and solute transport suite currently under development that is intended to serve as both a preand post-processor to MODFLOW. As a pre-processor, FRACK generates and maps networks of deterministic and/or stochastic fractures onto a regularly-spaced finitedifference grid, according to a fracture continuum method that closely approximates flow solutions to ...

Abstract This study used GMS-Modflow to investigate the ten-year groundwater potential in Concepcion, Tarlac. region Central Luzon, Philippines, with limited surface water, depends on as its primary freshwater source. The water demand projection estimated an increase of 38.5% from 2020 2030; hence, higher abstraction is perceived next ten years. To deviate risk associated reliance groundwater, ...

One of the most essential and appropriate groundwater model components is accurate information of the recharge values among input data often introduced to the model as the percentage of rainfall of aquifers. The recharge values are influenced by many temporal and spatial factors. Firoozabad plain is one of the suitable plains for agriculture in the Fars province in which utilization of groundwa...
