Abstract

This paper presents the impact assessment of the tunneling works on aquifer’s hydrogeology in the area of Chennai metro rail corridor using groundwater numerical model (MODFLOW3D). The comprehensive environment model is used to estimate the groundwater flow system and the groundwater levels in the study area, during the tunneling period. The comprehensive environment modeling period was selected from 1995 to 2016. According to the available data and the project phasing. Three scenarios are chosen according to the time schedule of the progress of the tunneling work. The comprehensive environment model was calibrated, validated and predicted for the change in the rate and direction of movement of ground water before and after the construction of underground tunnel sections. The comprehensive environment model shows increase and decrease of water levels in the observation wells of the study area due to the obstruction created in the ground water flow regime.
