ESTIMATION METHOD OF TRANSVERSE DISPERSIVITY BASED ON VERTICAL SALT CONCENTRATION DISTRIBUTION IN COASTAL AQUIFER

Mixing between fresh and salt waters at aquifer regional scale and identification of transverse dispersivity

Numerical Simulation and Estimation of the Transvers Macrodispersivity Coefficient of Aqueous Phase (Miscible) Contaminants of Salt Water in a Heterogeneous and Homogeneous Porous Media

Deterioration of groundwater resources in coastal regions due to the progression of saline water in aquifers in these regions is currently one of the important issues in providing water needs in these areas. In coastal regions, saline water enters the aquifer from below in shape of wedge. Due to the difference in the density between fresh and salty water, an interface zone forms between two flu...

Simulation of Seawater Intrusion in Coastal Confined Aquifer Using a Point Collocation Method Based Meshfree Model

Seawater intrusion caused by groundwater over-exploitation from coastal aquifers poses a severe problem in many regions. Formulation of proper pumping strategy using a simulation model can assure sustainable supply of fresh water from the coastal aquifers. The focus of the present study is on the development of a numerical model based on Meshfree (MFree) method to study the seawater intrusion p...

Estimation of Subsidence Potential Index Using the PCSM Method and Fuzzy Model in Ardabil Plain Aquifer

Recently, land subsidence due to natural and human factors changed to catastrophic destruction for the residential, agricultural and industrial areas. In this study, the high potential subsidence areas of Ardabil plain were identified to control and manage this phenomenon. Thus, the seven effective parameters on the subsidence were rated and weighted and the subsidence potential index (SPI) was...

Relation of hydraulic conductivity and dispersivity to scale of measurement in a carbonate aquifer

Tests on several scales were analyzed and conducted in a dolomite aquifer of southeastern Wisconsin to examine the variation of hydraulic conductivity and longitudinal dispersivity with scale of measurement. Scale behavior of hydraulic conductivity was shown to be dependent on the hydrofacies. In vuggy fades dominated by porous flow hydraulic conductivity increased relative to scale linearly wi...
