Abstract
This manuscript presents a comprehensive analysis of groundwater recharge techniques applicable to urban areas, focusing exclusively on technologies and methodologies developed up to the year 2015. Urbanization has significantly altered natural infiltration processes, leading to declining groundwater levels, increased surface runoff, and degraded water quality. To address these challenges, various engineered and nature-based recharge solutions have been implemented worldwide. This paper synthesizes key findings from studies published through 2016, but only considers techniques conceived or practiced by 2015. Following an introduction to the context and importance of urban recharge, we examine detailed case studies illustrating successful implementations in diverse climatic and geological settings. We then identify persisting research gaps, outline the methodologies deployed in comparative evaluations, present results highlighting performance metrics, and conclude with recommendations for future practice. Ten authoritative references up to 2016 are provided.
