EFFECT OF QUARRYING ON THE HYDRODYNAMICS OF WATER TABLES

EFFETS DE CREUSEMENT DE CARRIERES SUR L'HYDRODYNAMISME DES NAPPES

PAPER PRESENTED TO THE QUARRY CONSULTANTS CONFERENCE, DECEMBER 1975. IN THIS PAPER, THE AUTHOR DISCUSSES THE PROBLEM OF THE INFLUENCE OF GRAVEL PIT EXCAVATION ON THE HYDRODYNAMICS OF THE WATER TABLE. IN PRACTICE THE QUESTIONS POSED CAN BE GROUPED AS FOLLOWS: (1) WHAT IS THE INFLUENCE ON THE WATER TABLE LEVEL? IS THERE A RISK OF EXCESSIVE OVERFLOW OR EXCESSIVE LOWERING? (2) WHAT IS THE RATE OF FLOW BETWEEN GRAVEL PIT AND WATER TABLE? THE LATTER QUESTION CONCERNS THE EFFECTS ON WATER QUALITY. BEFORE MODIFYING THE EXISTING EQUILIBRIUM BY THE FORMATION OF A GRAVEL PIT, A PRIOR STUDY MUST BE CARRIED OUT, WHETHER HYDRODYNAMIC, ECONOMIC OR CONCERNING WATER QUALITY. IN THE FIRST PART THE AUTHOR REVIEWS THE FACTORS WHICH HAVE TO BE TAKEN INTO ACCOUNT IN THE HYDRODYNAMICS STUDY, AND THEN CONSIDERS THE METHODS WHICH LEAD TO THE EVALUATION OF THESE INFLUENCES.
