PERVIOUS CONCRETE AS A SUSTAINABLE SOLUTION FOR GROUNDWATER RECHARGE: A COMPREHENSIVE REVIEW OF MATERIAL PROPERTIES AND FLUID FLOW DYNAMICS

Abstract

Rapid urbanization and climate change have exacerbated challenges related to water management, particularly in urban areas where impervious surfaces prevent natural groundwater recharge. Pervious concrete has emerged as a promising sustainable solution to address these challenges by facilitating water infiltration while maintaining structural functionality. This review synthesizes current knowledge on pervious concrete's material properties and fluid flow dynamics relevant to groundwater recharge applications. The paper examines fundamental principles of fluid flow through porous media, permeability characteristics, factors affecting hydraulic performance, and groundwater recharge mechanisms. Current modeling and simulation approaches are evaluated, highlighting their capabilities and limitations. Research gaps identified include the need for long-term performance studies, regionalized mix design optimization, and integration with smart infrastructure technologies. This comprehensive analysis provides valuable insights for engineers, urban planners, and policymakers seeking sustainable solutions for water management and groundwater recharge in increasingly water-stressed urban environments.
