Karst groundwaters vulnerability assessment methods

Travaux de l'Institut de Speologie Emile Racovitza, 2008
A major socio-economic and scientific issue is represented by karst hydrostructures vulnerability mapping, which qualitatively and quantitatively highlights their exposure degree. Two research trends have been developed, one taking into account the environment features exclusively – the aquifer and protective cover type, permeability, aquifer depth ...
