Abstract

The paper presents the investigations into the decline in groundwater level recorded at national groundwater monitoring stations in Daegu Metropolitan City, Korea. The effect of precipitation and the pumping of wells in nearby areas was considered, but it was concluded that the main influence was the construction of a 1,110 m subway line some 250 m from the monitoring station. This was checked using a simplified conceptual model, which gave results consistent with field observations and suggested that groundwater levels may be depressed for a period of 10 years or more.

Résumé

L’article présente les travaux relatifs à l’étude de l’abaissement du niveau piézométrique mesuré à la station de suivi hydrogéologique des nappes de la ville de Daegu en Corée. Les effets des précipitations et des puits de pompage dans les zones voisines ont été considérés, mais la conclusion a été que la cause principale était la construction d’une ligne de métro de 1110 m de longueur, à environ 250 m de la station de mesure. Ceci a été vérifié grâce à un modèle conceptuel simplifié qui a donné des résultats cohérents avec les observations de terrain et a permis de considérer que les niveaux piézométriques pourraient rester déprimés pendant une période de 10 ans ou plus.
