Senthilkumar, L. Elango] Modélisation de l'impact d'une barrière souterraine sur l'écoulement des eaux souterraines dans le bassin inférieur du fleuve Palar, sud de l'Inde Groundwater modelling is widely used as a management tool to understand the behaviour of aquifer systems under different hydrological stresses, whether induced naturally or by humans. The objective of this study was to assess the effect of a subsurface barrier on groundwater flow in the Palar River basin, Tamil Nadu, southern India. Groundwater is supplied to a nearby nuclear power plant and groundwater also supplies irrigation, industrial and domestic needs. In order to meet the increasing demand for groundwater for the nuclear power station, a subsurface barrier/dam was proposed across Palar River to increase the groundwater heads and to minimise the subsurface discharge of groundwater into the sea. The groundwater model used in this study predicted that groundwater levels would increase by about 0.1-0.3m extending out a distance of about 1.5-2km from the upstream side of the barrier, while on the downstream side, the groundwater head would lower by about 0.1-0.2m. The model also predicted that with the subsurface barrier in place the additional groundwater requirement of approximately 13,600m3/day (3 million gallons (UK)/day) can be met with minimum decline in regional groundwater head.
