The phenomenon of climate change is not confined to our era, andevidenceindicatesthattheEarthhasfacedclimatechangeindifferentperiods, although this issue in the present era attracts the attention of many of the world’s scientific and political societies. Any change in the climate can be due to natural climaticchangeortheresultofhumanactivities.Suchachangecanoccurintemper- ature,rainfall,humidity,weatherpatterns,wind,radiation,andotherclimaticvari- ables.However,evenasmallchangeintheclimateconditionscanleadtotangible changesinhydrologyandthesensiblewaterresourcesystems.Theimpactsofclimate change on water resources include the changes in rainfall and runoff patterns, sea level,landuse,waterdemand,andmanyotheraspects.Thenegativeeffectsofthis phenomenononwaterresourcescancauseirreparabledamages.Thus,identification oftheseeffectsandtheirreasonsisessential.Investigationofsuchchangescanfacil- itatethestudiesonaseriesofhydroclimatic,economic,andsocialproblemssuchas droughts,floods,foods,andhumanmigration. In this book, to gain a comprehensive understanding of climate change, water expertscanbenefitthecontentofthreeseparatedsectionsaccordingtotheirback- ground.InthePartI,basicconceptsofclimatechange,itsnaturalandanthropogenic drivers, and its effects on water resources, from both quality and quantity aspects, arediscussed.Resultsoftheaccreditedresearchesshowthatgreenhousegasestake the first place in the consistent growth of the radiative forcing and the Earth’s energy level since the 1950s. Increasing temperature and decreasing precipitation havereducedthedischargeofsurfacerunoffsindifferentpartsoftheworld,which leadstoadeclineinthelevelofgroundwateraquifers.InPartII,climaticscenarios and IPCC reports are discussed. In order to analyze future climate conditions in water resource studies, we explain several categories of climate models, including EnergyBalanceModels(EBMs),radiative-convectivemodels,andGeneralCircula- tionModels(GCMs).Beingmostcomprehensive,GCMshavebeenwidelyapplied forfutureclimatechangeprojectionsusingdifferentscenariosofpopulationgrowth, greenhousegasemissions,andland-usechanges.Asthefinalstepinclimatechange v vi Preface studies, downscaling method, including statistical and dynamic, is explained thor- oughly.ThelastPartfocusesonwaterresourcemodelingunderclimechangecondi- tions.

Mirzaetal.(2003)examinedtheimpactsofglobalwarmingandclimatechange on the possibility of flooding of the Ganges–Brahmaputra–Meghna (GBM) river basin in Bangladesh using four General Circulation Models (GCMs). The output of the GCM models was used as an input of the Mike11-GIS hydrological model. TheirresultsshowedanincreaseintheaverageofmaximumdischargesintheGBM, whichpotentiallyledtoflooding. Rosenzweig et al. (2004) assessed the influences of the changes in agricultural waterdemandandtheavailabilityofwaterinducedbyclimatechangeonirrigation reliabilityusingaseriesofmodels,includingtheWaterBalance(WATBAL)model forwatersupply,theCeres-MaizeIndexModel,theSoygromodel,andtheCropwat B O.Bozorg-Haddad( )·S.Jafari DepartmentofIrrigationandReclamationEngineering,FacultyofAgriculturalEngineeringand Technology,CollegeofAgricultureandNaturalResources,UniversityofTehran,31587-77871 Karaj,Tehran,Iran e-mail:[email protected] S.Jafari e-mail:[email protected] X.Chu DepartmentofCivilandEnvironmentalEngineering,Dept.2470,NorthDakotaStateUniversity, Fargo,ND58108-6050,USA e-mail:[email protected] ©TheAuthor(s),underexclusivelicensetoSpringerNatureSingaporePteLtd.2022 1 O.Bozorg-Haddad(ed.),ClimateChangeinSustainableWaterResourcesManagement, SpringerWater,https://doi.org/10.1007/978-981-19-1898-8_1 2 O.Bozorg-Haddadetal. modelforproductoperation,andtheWaterEvaluationandPlanning(WEAP)model for water demand forecasting, evaluation, and planning. These models were used in conjunction with different climate change scenarios to evaluate the adaptation strategiesofwaterresourcesinmajoragriculturalareasinArgentina,Brazil,China, Hungary,Romania,andtheUnitedStates.Theresultsshowedthateveninrelatively water-rich areas, the effects of global warming on agricultural water demand and theincreasedwaterdemandduetourbanizationwouldrequireimprovedirrigation technologyandwatermanagement. Zhaoetal.(2005)investigatedtheresponseofclimaticvariablestogreenhouse gasemissionsinSouthAfricabyusingtheoutputsofthreeGCMsandB2scenarios from the set of Special Report on Emission Scenario (SRES). The simulations for most parts of South Africa indicated that by the end of the twenty-first century, rainfallwoulddropby8.2%.Batesetal.(2008)foundfromtheirstudyontheTsha RolpaGlacierLakeinNepalthatduetorisingtemperaturesinrecentyearsandthe meltingofthelake’sglaciers,thelake’swaterareaincreasedfrom0.23km2in1957 to1.65km2in1997,whichaddedabout100millionm3ofwatertothelake.Sincethe waterinthelakewasmaintainedonlybyitsicymasses,theincreaseinthisvolume elevatedtheriskofdevastatingfloods. By analyzing the effects of climate change on river flow in Northern China, Zhenmei et al. (2008) also examined the trend of annual flow changes in the past 50yearsusingtheMann–Kendalltest.Theyfoundthatclimatechangereducedthe average annual flow rate by 64% and decreased the amount of rainfall. Traynham et al. (2010) assessed the effects of climate change and population growth on the water resources system of the Puget region in the United States. The response of thewaterresourcessystemtofuturewaterdemandsundertheinfluenceofclimate change was examined for different cities in the Puget area. Three GCMs and two emission scenarios were used to assess the region’s water supply over a 75-year period.Theperformanceofthewatersupplysystemineachcitywasdeterminedby thereliabilityandfirmyieldcriteria.Theresultsshowedthatclimatechangewould reduce the future system’s yield, and the existing operation policies needed to be changedtomeetthefuturedemand. Tabarietal.(2011)studiedtheaverage,maximum,andminimumannualtrendsof rainfallandtemperatureseriesat13stationsinwestern,southern,andsouthwestern Iran for the period of 1966–2005 to understand how global warming affected the regional climate. Their results showed that the average, maximum, and minimum annualtemperaturesincreased0.412,0.452,and0.493°Cperdecade,respectively, whiletherainfalltimeseriesexhibiteddifferentchangingpatterns(i.e.,increasing– decreasingtrends)throughouttheregion.Theirstudyalsoindicatedthattherewasa needformoreresearchonhumanimpactsontheenvironmentasafactorofclimate change. Georgakakosetal.(2012)assessedtheadaptivereservoirmanagementstrategies under climate change in the Central Valley of Northern California. The reservoir management assessment included the adaptive policy with the developed Inform Decision Support System (INFORM DSS) and the current policy obtained from the Department of Water Resources Planning Simulation (DWRPS).
