Modeling an Aquifer: Numerical Solution to the Groundwater Flow Equation
Groundwater pp Cite as. One can infer the past behaviour of an aquifer system from the available earlier field records, but there is no way of computing the future behaviour of the regional aquifer system unless it is actually subject to the stresses. A full-scale experiment would be prohibitively costly and time consuming. A groundwater model is thus a simplified version of the real system that approximately simulates the input-output stresses and response relations of the system. One has to understand here that normally the real system is simplified to model the system as such there is no unique model for a given groundwater system.
Rubio-Arellano, D. Taking into account some geophysical parameters we develop a computational routine, in the Finite Difference Method, which solves the resulting elliptic partial equation, both in a homogeneous isotropic and in a homogeneous anisotropic media. 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 computational tool for the analysis of groundwater dynamics. One of the most powerful tools to advance theoretical and practical knowledge in the characterization of water flow through ground porous media are computational numerical models, which must always be compared and calibrated with experimental measurements [ 1 , 2 ]. In the practice it is common to carry out these kinds of studies with a wide combination of geophysical methods [ 3 ]. Physical models are often given in terms of partial differential equations, which for the specific case of groundwater dynamics they turn out to be analytically unsolvable when one tries to find a solution over realistic domains and conditions.

Hydrogeology hydro- meaning water, and -geology meaning the study of the Earth is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust commonly in aquifers. The terms groundwater hydrology , geohydrology , and hydrogeology are often used interchangeably. Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains.
In this study, analytical models for predicting groundwater contamination in isotropic and homogeneous porous formations are derived. The impact of dispersion and diffusion coefficients is included in the solution of the advection-dispersion equation ADE , subjected to transient time-dependent boundary conditions at the origin. A retardation factor and zero-order production terms are included in the ADE.

In general, groundwater flow and transport models are being applied to investigate a wide variety of hydrogeological conditions besides to calculate the rate and direction of movement of groundwater through aquifers and confining units in the subsurface. Transport models estimate the concentration of a chemical in groundwater which requires the development of a calibrated groundwater flow model or, at a minimum, an accurate determination of the velocity and direction of groundwater flow that is based on field data. All the available hydrogeological, geophysical and water quality data in Musi basin, Hyderabad, India, were fed as input to the model to obtain the groundwater flow velocities and the interaction of surface water and groundwater and thereby seepage loss was estimated. This in turn paved the way to calculate the capacity of the storage treatment plants STP to be established at the inlets of six major lakes of the basin. The total dissolved solid was given as the pollutant load in the mass transport model, and through model simulation, its migration at present and futuristic scenarios was brought out by groundwater flow and mass transport modeling. The average groundwater velocity estimated through the flow model was 0. The capacities of STP of various lakes in the study area were estimated based on the lake seepage and evaporation loss.
