GROUNDWATER FLOW THROUGH A MILIOLITE LIMESTONE AQUIFER.

This paper describes a study of groundwater flow in a coastal Miliolite limestone aquifer in western India. An examination of field information suggested that the transmissivity of the aquifer varies significantly between high and low groundwater heads. Pumping tests indicate that this is due to the development of major fissures in the upper part of the aquifer. A regional groundwater model with varying transmissivities is used to represent the field behavior. The model is also used to examine the effect of artificial recharge on the alleviation of saline intrusion problems in the coastal area.
