Session E: Discussion

Dr K. R. RUSHTON (Paper g)

It has been said that the analysis of groundwater flow problems is like a detective story, following clues until a solution is found. Since the flow takes place underground, the investigator never sees what is happening. Also the investigation uses the skills of many disciplines, with a mathematical model used to collate all the results.

2 . Several different types of model are available. However, in contrast to many of the surface water models, all the groundwater models are based on the same assumptions and idealizations and should give the same results. The choice of model depends on the nature of the problem as well as on the experience of the investigator and the facilities available.
