More than 80 % of the annual flow in the Ganges River occurs during the 4-month monsoon, resulting in widespread flooding. During the rest of the year, irrigation, navigation, and ecosystems suffer because of water scarcity. Storage of monsoonal flow for utilization during the dry season is one approach to mitigating these problems. Three conjunctive use management strategies involving subsurface water storage are evaluated in this study: Ganges Water Machine (GWM), Pumping Along Canals (PAC), and Distributed Pumping and Recharge (DPR). Numerical models are used to determine the efficacy of these strategies. Results for the Indian State of Uttar Pradesh (UP) indicate that these strategies create seasonal subsurface storage from 6 to 37 % of the yearly average monsoonal flow in the Ganges exiting UP over the considered range of conditions. This has clear implications for flood reduction, and each strategy has the potential to provide irrigation water and to reduce soil waterlogging. However, GWM and PAC require significant public investment in infrastructure and management, as well as major shifts in existing water use practices; these also involve spatially-concentrated pumping, which may induce land subsidence. DPR also requires investment and management, but the distributed pumping is less costly and can be more easily implemented via adaptation of existing water use practices in the basin.en-USCC BY-NC-ND 3.0 IGOFLOODINGDEEP WELLSRIVER ECOSYSTEMSGROUNDWATER STORAGECALIBRATIONHYDROGEOLOGYFLOWCANAL WATERDAMSAGRICULTURAL PRODUCTIONPUMPSWATER CRISISBANK FILTRATIONRIVER FLOWAGRICULTURAL DEVELOPMENTAQUIFERWATER SUPPLYWATER RESOURCEGROUNDWATER RECHARGERIVER BASINSDOMESTIC WATERRESERVOIRSLEAKAGE RATESURFACE WATERGLOBAL WATER CRISISFLOOD MANAGEMENTCHANNELSDAM CONSTRUCTIONWATER TOWERSWATER TABLEGROUNDWATER PUMPINGWATER RESOURCESWATER PUMPINGWATER STORAGEADVERSE ENVIRONMENTAL IMPACTSWATER MANAGEMENTSEEPAGECONDUCTIVITYFLOODSBASINSSEDIMENTSCONSTRUCTIONWATER USEWATERMANAGING WATER RESOURCESWATER RESOURCES MANAGEMENTRAINFALLSCIENCESPOLLUTIONWATER USE PATTERNSWATER SCARCITYRESEARCHGROUNDWATER IRRIGATIONAQUIFERSIRRIGATION WATERFARMERSCHEMISTRYANNUAL RAINFALLRUNOFFSUBSURFACE WATERTRANSBOUNDARY WATERSENVIRONMENTAL ENGINEERINGPERMEABILITYINTEGRATED WATER MANAGEMENTGROUNDWATER WITHDRAWALPUMPING RATESBASINWATER TABLESLEAKAGESPECIFIC YIELDECOSYSTEMUNSATURATED ZONESUB-BASINSUBSIDENCEGROUNDWATER USEWATER RESERVOIRSCLIMATE CHANGECANAL SYSTEMSDOWNSTREAM USERSDIVERSIONRIVER BASINLOWER WATER TABLECONJUNCTIVE USEWATER DEMANDWATER TABLE DEPTHENVIRONMENTAL IMPACTSWATER POLICYSURFACE SEDIMENTSCANALSPUMPING RATECATCHMENTDRY SEASONRIVERSINTENSIVE GROUNDWATER ABSTRACTIONRECHARGESTRATIFICATIONRIVER CONDITIONSGROUNDWATER ABSTRACTIONWELLSDOMESTIC WATER SUPPLYWATER AVAILABILITYARTIFICIAL RECHARGEPUMPINGSALINITYWATER NEEDSENGINEERINGMANGROVEIRRIGATIONNITROGENGROUNDWATERRAINFALL DISTRIBUTIONWATER USERSWATER-SUPPLY SYSTEMCONSERVATIONIRRIGATION WATER SUPPLYWATER LOSSWATER CHEMISTRYWATERSPUMPING WELLSTUBE WELLSAVAILABLE WATERJournal ArticleWorld Bank10.1596/24093
