Get this from a library. Numerical modelling of an aquifer system with intermittent recharge. [R E Volker; Burdekin Artificial Recharge Study.]. Finally, the model is used for predicting the system behavior under different groundwater recharge scenarios.

Numerical simulations and analytical approximations reveal that the studied aquifer can provide fresh water under different groundwater recharge conditions and has the capacity to smooth the effects of short drought periods Author: Francesca Petronici, Estanislao Pujades, Anna Jurado, Marco Marcaccio, Lisa Borgatti.

After calibration of the numerical model, this routine is used to begin a study of the Ayamonte-Huelva aquifer in Spain, a modest analysis of the system is given, and we compute the average discharge vector as well as its root mean square as a first predictive approximation of the flux in this system, providing us a signal of the location of best exploitation; long term goal is to develop a complete Author: V.

Vázquez-Báez, A. Rubio-Arellano, D. García-Toral, I. Rodríguez Mora. Numerical modeling using FRAC3DVS was used to understand groundwater flow and contaminant transport in a complex granular aquifer system contaminated. The numerical model was developed by getting a thorough understanding of the Southern Aquifer system in terms of its geology, recharge-discharge areas, current.

Numerical long-term assessment of managed aquifer recharge from a reservoir into a karst aquifer in Jordan The intersection point between these cross-sections was set up to separate the system into a “recharge model” (reservoir and recharge wells) and an “abstraction model” (Hidan wellfield), which made the calibration process Cited by: 9.

Development of conceptual groundwater flow model serves as a prerequisite to develop a numerical model and hence is a foundation to mathematically model the AG aquifer system to seawater intrusion.

Thus, modelFile Size: 1MB. Abstract: Managed aquifer recharge (MAR) is the purposeful recharge of an aquifer for later recovery or environmental benefits and represents a valuable method for sustainable water resources management. Models can be helpful tools for the assessment of MAR systems.

This reviewCited by: Managed Aquifer Recharge (MAR) is promoted as an attractive technique to meet growing water demands. An impediment to MAR applications, where oxygenated water is recharged into anoxic aquifers, is the potential mobilization of trace metals (e.g., arsenic).

While conceptual models for arsenic transport under such circumstances exist, they are generally not rigorously evaluated through numerical Cited by: The governing equations for steady state and non-steady state (transient) groundwater flow, are presented together with a brief overview of a range of modelling techniques, including both analytical and numerical models, the use of diffuse recharge as a model calibration tool and recent developments in the field of inverse modelling are also discussed.

The aerial extent of the model domain was selected such that the lateral boundary conditions did not impact the groundwater flows around the ASTR system. The bottom and top model boundaries were set as no flow, thus assuming an impermeable aquifer basement and negligible natural recharge to the aquifer (Institute of Water Modelling, ).

The modelling involves several steps: conceptual karst modelling, spatio-temporal recharge evaluation, simulation of a conduit network, soil-epikarst assessment and mapping and mathematical modelling of all of the flow processes. An inverse procedure is used for model calibration, using daily spatially distributed discharge : Eulogio Pardo-Igúzquiza, Sergio Martos, Juan Antonio Luque, Juan José Durán, Carolina Guardiola-Albe.

The numerical model constitutes the main method used to solve the groundwater quantity management problems and to evaluate the groundwater flow mixing between different aquifer levels. A groundwater numerical model for El Hicha Basin, an arid area of southeast Tunisia, was developed using MODFLOW software, a Geographic Information System (GIS.

The hydraulic conductivity and recharge values from the pilot points calibration ranged from 1 to 75 m/d and × m3/d to × m3/d.

The calculations of the model showed that the average recharge rate amounts l/s/km2 or mm/year. The estimated recharge suggests a high groundwater potential for the by: 7. In this study, finite difference method is used to solve the equations that govern groundwater flow to obtain flow rates, flow direction and hydraulic heads through an aquifer.

The aim therefore is to discuss the principles of Finite Difference Method and its applications in groundwater modelling.
