GIS AND MATHEMATICAL MODELLING FOR THE ASSESSMENT OF VULNERABILITY AND GEOGRAPHICAL ZONING FOR GROUNDWATER MANAGEMENT AND PROTECTION

摘要

The groundwater group of the European Community Commission (EEC) held a meeting on February 91, in the European Water Institute, in Brussels, with the purpose of establishing an international agreement on common methodologies for the elaboration of a groundwater resource inventory for all Member-States. Such an inventory has been made in the past, between 1979 and 1981, for all countries that were Community Members-States at the time. The existing inventory needed to be updated to new Members-States, e.g. Spain, Portugal and the new Lander of Germany.
