A few remarks about groundwater modelling
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2009, Vol 436, Issue 436
Abstract
Nowadays groundwater flow modelling is the basic method of solving complicated hydrogeological problems. Wide interests of numerical modelling started in the 1980s as a result of easier access to personal computers and calculation programs adjusted to PC capabilities. The main advantages of numerical modelling are speed, accuracy and reliability of calculations. Groundwater modelling require first of all both understanding flow processes and phenomena as well as appropriate approach, based on connecting geological knowledge with computer hardware and software capabilities. Important attributes of groundwater modelling are possibilities to make predictions and presenting results as a water budget or water table contour maps with flow lines.
