This is achieved by: (a) obtaining available geologic, hydrologic, and geochemical information on coastal aquifers of Bangladesh; (b) developing groundwater flow and salt transport models representing general features and conditions along the coast of Bangladesh; and (c) simulating potential changes in the groundwater systems due to various aspects of human activity and climate change. The simulation analysis will focus on both the pattern and response time of the saltwater-freshwater distribution in subsurface aquifers, with a view towards sustainability of current and future water use under stress due to climate change. The study is aimed at understanding processes and rates of change for systems representative of a range of conditions in coastal Bangladesh, but it is expected that regional and local differences occur. Thus, only general conclusions and guidance should be drawn from this work.en-USCC BY 3.0 IGOACCRETIONADSORPTIONAGRICULTURAL WATERAQUATIC RESOURCESAQUIFERARSENICAUGMENTATIONBAYBRACKISH WATERCALIBRATIONCARBONCHANNELSCHEMISTRYCHLORIDECLAYCLAY CONTENTCLIMATE CHANGECOASTCOASTAL AREACOASTAL COMMUNITIESCOASTAL DEVELOPMENTCOASTAL FISHERIESCOASTAL PLAINCOASTAL REGIONCOASTAL RESOURCESCOASTAL ZONECOASTAL ZONE MANAGEMENTCOASTLINECOLLOIDSCOMPACTIONCONDUCTIVITYCONFLUENCECONSTRUCTIONCOVERINGCRABSCROP IRRIGATIONCROP YIELDSDEEP WELLSDELTADIFFUSIONDISCHARGEDOMESTIC USEDOMESTIC WATERDRAINAGEDRINKING WATEREMISSIONSENGINEERINGENVIRONMENTAL CONSERVATIONEROSIONEVAPORATIONEVAPOTRANSPIRATIONEXPORTFARMERSFARMINGFISHERIESFLOOD IRRIGATIONFLOODINGFLOODSFLOW REGIMESFLUVIAL EROSIONFORESTRYFRESHWATERFRESHWATER FLUXFRESHWATER RESOURCEGASGRAVELGROUNDWATERGROUNDWATER ABSTRACTIONGROUNDWATER PUMPINGGROUNDWATER QUALITYGROUNDWATER RECHARGEGROUNDWATER RESOURCESHEATHIGH SEAHUMIDITYHYDRAULIC CONDUCTIVITYHYDROGEOLOGYHYDROLOGYICEINFILTRATIONINTAKESIRONIRRIGATIONIRRIGATION WATERISLANDLAND DEGRADATIONLAND SURFACELAND USELEAKAGELOW PERMEABILITYLOW TIDEMANGANESEMANGROVEMARINE FISHERIESMEAN SEA LEVELMEASUREMENTSMETEOROLOGYMINERAL RESOURCESMINERALSMONITORING PROGRAMNATURAL RESOURCESOBSERVATION WELLOCEANSPARTICULATEPARTICULATE MATTERPARTNERSHIPPERMEABILITYPHPIPED WATERPOLLUTIONPONDSPOPULATION DENSITYPOROSITYPRECIPITATIONPRESSUREPROGRAMSPUBLIC HEALTHPUBLIC PARTICIPATIONPUMPINGPUMPING RATEPUMPING WELLSPUMPSQUALITY OF WATERRAINFALLRIVER FLOWRIVERSRURAL DEVELOPMENTSAFE WATERSALINE CONDITIONSSALINE WATERSALINITYSALT TRANSPORTSALTWATER INTRUSIONSANDSEASEA LEVELSEAWATERSEDIMENTSEDIMENTATIONSEDIMENTSSHALLOW WELLSSHRIMPSILTSPRINGSSTORM SURGESUBSIDENCESUBSURFACE WATERSURFACE WATERSUSTAINABLE MANAGEMENTTECTONICSTHERMAL ENERGYTIDETOPOGRAPHYTRANSMISSIVITYTSUNAMIUNSATURATED ZONEWATER BODYWATER ELEVATIONWATER LEVELWATER MANAGEMENTWATER NEEDSWATER QUALITYWATER RESOURCES PLANNINGWATER SUPPLYWATER TABLEWATER TABLE AQUIFERSWATER USEWATER WELLSWATERSWELL DRILLINGWELLSWETLANDSWIND SPEEDReportWorld Bank10.1596/27489
