    A Review on Optimal Dewatering of Aquifers Using

    Keywords: dewatering, optimization, ground water modelling I. INTRODUCTION Water that occurs below the surface of earth is generally termed as groundwater. The main source of groundwater is infiltration of rainwater. The infiltrated water percolates deeply after meeting soil requirements and gets stored as groundwater. The geological formations which store water and are sufficiently permeable
