Groundwater Modelling: from Geology to Hydrogeology
نویسنده
چکیده
Three-dimensional mapping has extensively developed in the last decade; geological mapping being the area where these developments are more striking. 3D geological mapping has a myriad of applications in the domains of basin analysis, geophysics, geostatistics, geothermal and energy resources, etc. A parallel domain of development has been three-dimensional groundwater modelling: regional groundwater systems, surface water-groundwater interactions, radioactive waste disposal, etc. Whilst these developments have substantially advanced both domains, we see that we are still lagging behind having a clear interface between geological mappers and groundwater modelers. Unfortunately, geologists and hydrogeologists are still working on their own fields more or less separately, and their communication is still poor. Science and technology and available tools abound, but both groups still do not take full advantage to benefit each other. This short essay is a recap, a synthesis of what we see today in the domains of 3D geological mapping and 3D groundwater modelling.

متن کاملManagement of groundwater resources of Mahvelat-Faizabad aquifer and evaluation of extent of saline water zone using numerical simulation
The unmanaged groundwater extraction and inadequate aquifer recharge is the major cause of groundwater depletion in different parts of the world. In this study, the groundwater flow system of Mahvelat-Feizabad aquifer (NE of Iran) has been numerically simulated using MODFLOW code in the GMS interface. The model, primarily, calibrated for steady state condition for the mean hydraulic values of o...

In this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. Novel hybrid method coupling artificial neural network (ANN) with genetic algorithm (GA) called ANN-GA, was utilised. Ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (HH) in the observation w...
متن کاملAssessment of groundwater under direct influence of surface water.
Waterborne pathogens are known to reside in surface water systems throughout the U.S. Cryptosporidium outbreaks over recent years are the result of drinking water supplied from such sources. Contamination of aquifers has also led to several reported cases from drinking water wells. With high resistance to typical groundwater treatment procedures, aquifer infiltration by Cryptosporidium poses a ...
