Comparative study between numerical and analytical groundwater modelling
This study compares analytical and numerical models for groundwater modelling. The focus of comparison is to investigate the change of the analytical results when there is only a partial penetration of the aquifer. Two methods of comparison are used, the first one consisting of calculating a radial distance from a shaft to the point where the drawdown is 0.3 meters with both models. The second metCan pen and paper groundwater models compete with computer programs? Could something as simple as a pen and paper equation on the back of an envelope compete with advanced and expensive computer programs? Surprisingly, the answer could be yes for sandy soils. When modelling how a construction project will affect the groundwater surface, it’s easy to assume that the more advanced the model is, the
