AnalyticalPerspectives
AsthepioneerscholarinthestudiesofinfrastructurePaulEdwards(Edwards2003)noted,infrastructureis“aslipperyterm”becauseitcan“meanessentiallyanyimportant,widelyshared,humanconstructedresources”(186‐7).Itisthusimportanttomakeexplicitthenotioninordertoclarifythepresentargument.Onerelevantaspectofinfrastructureisitsroleincontrollingtheflowofmaterialsnecessaryforsustainingthesociety(Larkin2013).EdwardspaysattentiontothisaspectbycitingthefollowingdefinitionbytheU.S.President'sCommissiononCriticalInfrastructureProtection(PCCIP):
"Byinfrastructure...wemeananetworkofindependent,mostlyprivately‐owned,man‐madesystemsandprocessesthatfunctioncollaborativelyandsynergisticallytoproduceanddistributeacontinuousflowofessentialgoodsandservices".(President'sCommissiononCriticalInfrastructureProtection1997:3sitedinEdwards2003:187)
Thisnotionofflowcontrolrelatestoanotherimportantaspectofinfrastructure,whichisthemediationofgeographicallyandtemporallydispersedactivities(StarandRuhleder1996;BowkerandStar1999).Infrastructurecontrollingwaterflowssuchaswaterworksthatconnectstreatmentplants,pipesandindividualhouseholdsmediatesdivergentactivitiessuchastheoperationoftheplantsandcookinginakitchen(Star1999).

IntheChaoPhrayaDeltathereisacomplexinterplaybetweendifferentinvisibleflowsintheseinfrastructures.Waterflowishererelatedtootherflows.Ontheonehand,theregion’sroadsystemcontrolsflowsoflandtransportandconnectvariouseconomicactivities.Ontheotherhand,inordertosustainthisterrestrialflowitisnecessarytokeeptheflowoffloodwateratbay.Thus,itiscrucialfortheprotectionoftheterrestrialinfrastructuretodrainexcessivewaterandextensivedrainagenetworksservethispurpose.Thesedrainagenetworkssignificantlyoverlapwitholderaquaticinfrastructure,originallydesignedtofacilitatewaterwaytraffic.TheentanglementbetweenterrestrialandaquaticinfrastructureplaysacrucialroleinstabilizingbothflowsofwaterandoftrafficandmaintainingthepresentlandscapeoftheChaoPhrayaDeltafullofhighways,concretebuildings,factoriesandcondominiums.Inordertounderstandthiscomplexinterplay,itisnecessarytounderstandthehistoricaltransformationofthedelta.Asweshallsee,thisisaprocessinwhichterrestrialinfrastructurewaslayeredupontheolderaquaticone.

Asindicatedbytheseexcerpts,architecturalandinfrastructuraldesignsinThailandhaveindeedchangeddrasticallyoverthepast100yearsandthishascertainlyimpactedonThaicities’adaptabilitytofloods.Butitisnotonlythebuiltenvironmentsthathavechanged.The“natural”environmentofthedeltahasalsochangedduetotheextensiveconstructionofwatermanagementfacilities,particularlyirrigationdamsandcanals.
HomanvanderHeide,thearchitectofthecurrentirrigationsysteminChaoPhrayaRiverBasin,describedthedeltaattheturnofthecenturyasfollows:
Theplain,wherenotcultivated,ischieflycoveredwithjunglegrass,whereherdsofelefants[sic]feedupon,brushwoodandbamboo.Extensiveforestsdonotexist.Exceptinthehighesttractsalongtherivers,evenclumpsoftreesarescarce,apparentlyinconsequenceofoccasionalfloodsandwantofproperdrainage.(HomanvanderHeide1903:3)
Beforethecompletionoftheirrigationsystem,whichHomanvanderHeidedesignedin1903(butwhichremainedonlypartlymaterializeduntil1957),thelowerpartofthedeltawasunpopulatedmarshland.Withoutanextensiveandwell‐organizednetworkofcanalsandsluicegates,theearly20thCenturydeltawasquiteaninhospitableplaceforagricultureandhumansettlements.Sincethedeltaisextremelyflat,mostofitsparts,exceptridgesalongtherivercreatedbyriverdeposit,wereannuallyflooded.Thusthelowerpartofthedeltabecameagiganticwaterzonedirectlyconnectedtothesea.Becauseinundationdrownedalltheyoungtreesintherainyseason,thelowerpartofthedeltawasalmostentirelydeforested.Simultaneously,theinlandareasnotadjuncttotheriversbecameextremelyaridinthedryseason.Accordingly,inmostofthedeltaitwasextremelydifficulttoevengetdrinkingwaternottomentionwaterforagriculture.Theseseverehydrologicalconditionspracticallyprohibitedhumansettlementsexceptonnaturalleveesalongtheriver(Takaya1987).

TheDeltaasReclaimableLand

TheworddeltaitselfisofGreekorigin.GreeksusedthisdesignationonthebasisofthesimilarityoftheshapesbetweentheletterΔ(delta)andtheestuarylandformoftheNileRiver.3 ItwasoriginallythepropernamegiventotheNileDeltabytheancientGreeks.Asapropername,deltawasalreadyinusewhenHerodotuswrotehisHistoryinthe5thcenturyB.C.ButtheworddidnotacquirethegenericmeaningbeforetheAlexandertheGreat’sinvasiontoIndiawheretheGreeksfoundsimilarlandformsatlargerivermouths.Strabo,thewell‐knownRomangeographer,citesseveralGreekwriterscomparingtheNileDeltaandthenewlyvisitedIndianalluvialareas.FrancisCeloriahasarguedthatthetermgraduallygainedgenericmeaningthroughthosecomparisons(Celoria1966).
Herodotuswell‐knownphrase“EgyptisthegiftoftheNile”,suggeststhatthesoilofthedeltaistransportedbytheriver,particularlyduringseasonalinundation(Herodotus1890).InthedynamichydrologicalconditionoftheNile,therelationshipbetweenfloodinganddepositoffertilesoilisquitevisible:seasonalfloodingreachedthedeltaaroundtheparticularperiodofayear,andtherecessionofwaterleftavisiblenewlayerofsoiluponthefield(Nagasawa2013).WhilewecannotassumeanydirectlinkagebetweenHerodotusandmodernEuropeanscienceandtechnology,thereareinterestingcommonalitiesbetweentheobservationsofthismythicalfatherofgeographyandthoseofmoderngeo‐morphologists.Bothviewriversasthecentralforcesthatmakeoflandscapes(Leopold,Miller,andWolman1964).

ModerninfrastructuralinterventionsinEuropeandeltasdatebacktotheearlyMiddleAges,particularlytotheDutchlowlands.Settlersinthecoastalareasreclaimedfenlandsbyconstructingdikesanddrainagechannels.TheinventionofwindmillssignificantlycontributedtotheimprovementofdrainageandtheDutchcontinuedtoexpandtheirfarmlandsintotheseaandseashorelakes.DutchtechnologyeventuallyspreadtomanyEuropeancountriesandreclamationofswampylandbecameonethefocusofmuchlanddevelopmentinEurope(Danner2005).
ButthoughtheChaoPhrayadelta’spresentterrestriallandscapewasactuallydesignedbyaDutchengineer,itwasnotthistechnologythatcreatedit.TheirrigationtechnologyappliedtotheChaoPhrayaDeltawasinsteadahybridandcolonialtechnologydevelopedinthetropicalcoloniesoftheDutchandBritishempires(Ertsen2010;Headrick1988).IrrigationwasindeedunnecessaryfortheNetherlandsandBritain,wherefarmerscouldcountonyear‐roundrainfall.Britain,themasterofmodernirrigationintheearly20thcentury,developeditsirrigationtechnologyincolonialIndia.TheirtechnologiesdevelopedaspartofefforttoreconstructdeterioratedirrigationcanalsdugbytheMughalEmpire.Eventually,theBritishconstructedtheirownirrigationschemesbothinthedeltasandinhighlandregions(Headrick1988).TheywereeventuallytransferredtootherBritishsemi‐coloniessuchasEgyptandMesopotamia(Nagasawa2013).OntheNile,theintroductionofnewirrigationsystemswereaccompaniedbytheconstructionoftheAswanLowDam,thelargesthydro‐engineeringconstructionintheworlduponitscompletionin1902.Thedamandirrigationmadeyear‐aroundcultivationpossibleintheNiledeltaandcompletelyremadethelandscapeandtheagrariansociety(Mitchell2002).Asithappens,theirrigationprojectoftheChaoPhrayaDeltawasinspiredbyandvisiblymodeledafterthisimpressiveaccomplishment(HomanvanderHeide1903).
Indeed,thecolonialoriginofirrigationalsoappliestothecaseofDutchtechnology.AlthoughwidelyknownfortheirmasteryofdeltawatermanagementinEurope,DutchengineersinitiallyhadnothingtoaddtotheexistingirrigationintheIndonesianarchipelago.Theirinitialinvolvementwasmostlylimitedtothemaintenanceofexistingirrigationworks.Butaftertheintroductionoftheforcedcultivationofsugarcane,Dutchengineerswererequiredtoconstructnewirrigationsystemsuitableforthislucrativecrop.BecausesugarcanewascultivatedonBalinesepaddyfieldsasasecondcrop,sugarcaneirrigationalsodeeplyinvolvedDutchengineersinpaddyfieldirrigation‐‐inwhichThailandintheearlytwentycenturyhadagrowinginterest(Ertsen,2010).

IncaseoftheChaoPhrayaDelta,thelackofstateinterestinagriculturealsostemmedfromthehydrologicalconditionofthedelta.YoneoIshiihaswrittenthatinthetimeoftheAyutthayaandearlyBangkokdynasties(from14thto19thcentury),thelowerChaoPhrayaDeltawas“abeltofmudstretchingbetweenthecontinentandthesea,which,undernaturalconditions,isunsuitableinhabitation.”(p.28)Giventhisamphibiouscharacterofthedelta,theancientcapitalofAyutthaya,located100kilometersfromthecoastalline,wasactuallytheoutlet

ThehydrologicalconditionsofthedeltamadetheAyutthayaandtheearlyBangkokdynastiesrelationshiptowatermanagementdistinctivefromothertraditionalpolitiesofTaipeoples,whoshareculturalandlinguistictraitsandhavehistoricalrelationswiththeSiamesepeopleinthecentralpartofThailand.MostofthelowlandpeopleinThailand,LaosandNorthwestVietnam,theShanStateinBurma,andpartofYunnaninChinaandAssaminIndiaspeakrelatedlanguagesandformsimilarpoliticalsystemsbasedonwetriceproduction.Theprincipalitieslocatedinintermountainbasinsdevelopedrelativelysmall‐scaleirrigationsystems,whichareusuallycollectivelyrunbyfarmers(Ishii1978;Tanabe1994).5 Thistypeofwatermanagementwasimpossibleinthedelta,whereSiameseimmigratedfromthenorthbeforethe13thcentury.

Butcanaldiggingwasnotlimitedtothestatesponsoredendeavors.Intheamphibiousdeltaenvironment,watercourseswereprimarytrafficroutesforeveryone.Farmersandtownsfolkdugsmallcanalsinordertocommutetothepaddyfields,tomakeaccesstothemainwatercoursesandopenupnewsettlements.Sincehumansettlementswerelimitedtothebanksofcanalsandrivers,aquaticinfrastructuresexemplifiedbytraditionalarchitectureandtownplanningdevelopedmainlyinthesecanalbanks.GeorgeFinlaysonwhovisitedthedeltaandBangkokin1820svividlyillustratesthisaquaticlifestyle:

In1902,thegovernmentofThailandledbytheKingChulalongkorn(RamaV)invitedtheDutchengineer,J.HomanvanderHeidefromtheDutchEastIndiestoexaminethepossibilitiestomodernizethecanalsystemandintroducingirrigation.HomanvanderHeidewasenthusiasticallydevotedtoirrigationengineering.BeforehisarrivaltoThailand,hehadtraveledinEgypt,JapanandItalyandconductedacomparativestudyofirrigationsystems(Brummelhuis2005).
Aroundthistime,theThaieconomyhadbecomeincreasinglydependentontheexportofrice,bothtotherisingdemandintheneighboringEuropeancoloniesandtothedeclineofsugarexport,whichhadbeenprimaryinthemid19thcentury(Daniels1996),buthadbeenalmostcompletelydestroyedbythefundamentaltechnologicalchangeintroducedbynewrefiningmethodsthatfacilitatedcolonialJava’sextraordinarycompetitivenessinthesugarindustry(Yamamoto 1998).Inthiscontextfurtherboostingofthedeltariceproductiongainedineconomicimportance,atleastintheeyesofsome.
However,althoughtheideaofirrigationenthusedKingChulalongkornandafewkeyministers,HomanvanderHeide’splantoconstructanirrigationnetworkdidnotcapturetheimaginationofmostoftheThaieliteincludingtheAgriculturalMinisterhimself(Brummelhuis2005).ThedecisiontoinviteHomanvanderHeidewasduetoamixtureoftheKing’sinterestinthepossibilityofstimulatingricecultivationandthecommonrecognitionamongThaielitesofthenecessityofintroducingmodernhydraulicstorehabilitatethetransversalcanals,whichhadbeensiltedupbythetidaleffectandbeguntogiverisetosalinityprobleminadjacentareas.Becauseofthedelta’sslightgradient,theriversonthe

Inthiscontext,thedecisiontobringinaEuropeanhadlesstodowithinterestinreproducingformsofcolonialirrigationthaninsupportingthetraditionalaquaticinfrastructure.CarefullyexaminingcorrespondencesbetweenthevanderHeide,theministerofagricultureandtheKing,theDutchanthropologistandhistorianHantenBruhmelhuisconcludedthattheThaigovernmentatthetimealmostcompletelylackedthenotionthatagriculturecouldbedevelopedbystateinterventionsuchasirrigationandreclamation.ThiswasinspiteofthefactthattheKinghimselfoccasionallymadesuggestionstothiseffecttohisministers.Asanaquatictrade‐orientedkingdom,agriculturaldevelopmentwassimplyoutsidethestate’svision;lefttotallyinthehandsoffarmersendeavoringtohelpthemselves(Tambiah1977).EventuallythislackinginterestledtothedeclineofHomanvanderHeide’smassiveirrigationplanduetoinsufficientresourcesandtolimitingtheroleofthisambitiousirrigationengineertotherehabilitationoftheexistingcanalsystem(Brummelhuis2005).
HomanvanderHeide’sirrigationschemewasindeedextremelyambitious,particularlyinthefinancialandpoliticalsituationofThailandintheearly20thcentury.Itencompassedtheentiredeltawatersystemandincludedthreenaturalwatercourses,theChaoPhrayamainstreamanditstwotributaries,ThaChinandNoi,aswellasnumerouscanals.JustliketheEgyptianAswanLowDamproject,vanderHeide’sChaoPhrayaschemecenteredontheconstructionofahugebarrageacrosstheChaoPhrayaatthetopofthedelta.ItwasdesignedtodivertwaterfromthemainstreamtotheThaChin,theNoiandanewlyconstructedcanal,eachofwhichwouldfunctionasirrigationcanals,distributingwatertotheentiredelta.TheinventivenessofHomanvanderHeide’sschemehasbeenacclaimedbyanumberoflater‐generationengineers(Brummelhuis2005).
Buttheinventivenessalsoexhibitsthetravelingnatureofdeltaknowledge.IntheGeneralReportforIrrigationandDrainage(Homanvander

Heide1903),vanderHeidecitesawidevarietyofreportsondeltas,fromthefamousWilliamWillcockreportsonthemodernizationofEgyptianirrigationbytheBritishtotheBulletinoftheCollegeofAgricultureattheTokyoUniversity.Indeed,itisthroughHomanvanderHeide’scontinuouscomparisonsbetweenEgypt,India,Japan,ItalyandJavathathecomestocharacterize,diagnoseandassessthepotentialoftheChaoPhrayaDelta.Asanobjectofstate‐engineeringinterventions,theChaoPhrayaDeltawasthusembeddedincolonialconnectionsamongnumerousdeltas;connectionsthoughwhich,engineers,reports,scientificarticlesandideasallcirculated.
HomanvanderHeide’sinnovativedesignwasnotimplementedbytheThaigovernmentfornearlyhalfacentury.AlthoughtheKingandatleastoneministerseemedtorecognizetheinnovativenessoftheplan,itlookedtomostoftheThaiministersasadisproportionatelyambitiousandriskyendeavor(Brummelhuis2005).Particularly,themostcostlypartoftheplan,theconstructionofthebarrageacrossthemainstream,onwhichtheentiresystemhinged,wasonlyrealizedintheformoftheChaoPhrayaDamin1957,andthenonlywithmassivefinancialsupportfromtheWorldBankandtheUnitedStates(Takaya1987).
Aftersubmittinghisreport,HomanvanderHeideremainedinThailandwithanappointmentasheadofthenewlyfoundedRoyalIrrigationDepartment.Inthispositionhewasengagedinanumberofcanalimprovementprojectsofmoremoderateambition.Becausethegovernmentagreedonthepotentialsofhismasterplanandhedecidedontheworkundertookbyhisdepartment,thesecanalimprovementprojectsweredesignedinlinewithhismasterplan.Atthesametime,however,thedepartment’sactivitieswerenecessarilydirectedtotheurgentissueofrehabilitatingtheexistingcanalsystemsthatservedasmaintrafficroutes.WhilevanderHeidecarefullydesignedinfrastructures,suchassluicegates,dikesandditches,tobeusefulforirrigationpurposeandeloquentlydeclaredtheir“true”purposeforirrigation,hissuccessiveandsuccessfulendeavorscontributedsignificantlytosustainingtheaquaticinfrastructureratherthantransformingitintoaterrestrialone.TheThainameofthedepartmentKromKlong,“CanalDepartment”,neatlyepitomizesthispoint(Brummelhuis2005).

realityitsrolewasmoreimportantthantheconstructionsuchasroadsandWesternstylebuildingssincedrainagebyirrigationcanalscreatedthedrylanduponwhichtheseterrestrialinfrastructureswereconstructed.
In1903,HomanvanderHeidehadalreadyforeseenthatirrigationcanalswouldopenupnewterrestrialpossibilitiessuchaspermanentsettlementintheinlandareas,orchardsandlivestock(HomanvanderHeide1903).Duetothecyclicalfloodingandaridity,mostoffarmerslivednearpaddyfieldsonlyinrainyseasons,whendrinkingwaterandthewaterwayconnectionfromthemaincanalstothefieldwereavailable.Irrigationcanalsthatretainedwaterinthedryseasonsmadeitpossibleforthesefarmerstobuildpermanentvillagesnearthefieldandthuscontributedtoeliminatingthemobilelifestyleinthedelta,whichcausedtroublefortaxationandpopulationsurveys(Brummelhuis2005).Theirrigationsystemalsodrainedexcessivewaterfromvillagesandadjacentareas,whichmeantthatvillagerswereabletocultivatefruittreesandraiselivestock.Theirrigationanddrainagenetworkintroducedaclearseparationofwaterandlandthatremainedstablethroughouttheyear.Thiswasobviouslyagreatadvantageforthedevelopmentofterrestrialagricultureandeconomicactivities.
Basedontheyear‐roundseparationofwaterandland,theconstructionofextensivehighwaynetworkssincethe1960shasdramaticallyalteredthemaintransportmeansinthedeltafromboatstocars.Thedevelopmentoftheroadnetworkbroughtaboutanoverallfigure‐groundreversalinthedeltatownscapes.Specifically,roadsweretraditionallybuiltparallelwithbutslightlydistancedfromriversandthusfacedthebackyardsofhouses,whosemainentrancesfacedriversandcanals.Asroadsbecamethedominantcommunicationandtransportroutes,theurbanspaceliterallyturnedaround.Nowbackyardsbecamefrontentrancesandriversideboatslips,tha,thetraditionalfrontentranceoftheriparianhouses,becamebackdoors.Inmanyplaces,theorientationofsocialspacewasthusdirectlyreversedfromtheriparianspacetotheroadside.
Thisurbantransformation,whichtookplaceinBangkokandmajorcities,wasonthewaythroughoutthe1970s.However,asaconsequence,Thailandstartedbeganexperiencingfloodingproblems.Sincenewlyconstructedterrestrialinfrastructureswerevulnerabletoflooding,floodprotectionbecameamajorconcernofwatermanagement.Inthemeantime,thematerializationofHomanvanderHeide’splan,whichbroughtirrigationtomostofthedeltacreatedunexpectedsideeffectsinceitalteredthepatternofwaterflowintheentiredelta.
Thenewcanalnetworksuppliedwaterprimarilytotherelativelyhighareasneartheriverchannels.Inthefurrow‐liketopologyofthedelta,higherplaces
19
arelocatedalongtherivers,andlow‐layingdepressionsarefoundbetweentherivers.Becauseofthistopography,irrigationcanalsprovidewatertothehigherriversideareasfirstandonlysubsequentlytothedepressedareasinbetween.Alongwithirrigationwater,drainagefromthehigherareasalsoflowsintolower‐lyingplaces.Inthisalteredwaterflowmorewaterconcentratesinthedepressedareasandthusfloodingintheseareaswereactuallyexacerbated(Takaya1987).
Thisinundationproblemhadafractalquality,sincetheproblemreplicatedacrossscales.Repeatingtheproblematthebasinlevel,atthemicrolevel,floodingalsooccurredintherelativelylowerlyingplacewithinirrigationtracts,usuallyplaceswherewateriscontrolledbyasluicegate.Thewaterlevelofirrigationtractsweregenerallycontrolledinordertokeepsufficientwaterinthehighestareas,andthesewereusuallytheareasclosesttotheriver,wherewaterfirstarrived.Becauseeverytracthasagradientthatrunsfromuppertolowerstream,thiswatercontroltendedtobringaboutmuchdeeperinundationinthelowerplaces,oftenlocatedclosetothesluicegatesthatcontrolledthedrainage(Molleetal.1999).
Thissystemofwatercontrolbroughtaboutthecoexistenceofthetraditionalandmodernformsofagriculturewithinthesameirrigationtract.Theintroductionofirrigationcreatedtheconditionsforagriculturalchangeathigherelevations.Intheupperlands,theirrigationdepartmentensuredawaterlevelsuitablefortheshortstemhighyieldcropvarieties,whichwerethemaintechnologybehindtheGreenRevolution.Thedepartmentalsodrainedwaterfromthefieldsinpreparationandharvestingperiodssothatfarmerscouldapplymachinery.IncontrasttotherapidchangesbroughtaboutbytheGreenRevolutiontechnologiesintheupland,however,lowlandfarmersadaptedtotheincreasinginundationproblemsbyusingthetraditionalmeans:floatingricevarieties.
Herewearewitnesstoaformofcoexistencebetweenaquaticandterrestrialinfrastructuresofagriculture.Ontheonehand,inthelowlayingplacesthetraditionalformofagriculturegainedevenfurtherimportanceduetothediversionofdrainagefromtheupperlands.Traditionalagricultureinfrastructureconsistedofhigherdikesaroundthepaddyfieldsthatkeptlargeamountsofwaterwithinthefield,oftraditionalfloatingricevarieties,ofhugeamountofhumanlaborforharvesting,and,sometimes,ofboatsforcultivatingonthefloodwater.Ontheotherhand,theagriculturalpracticeinthehigherareasweretransformedintoanewterrestrialformcomprisedoflowerdikesthatpreventedfloodwaterfromenteringintothepaddy,ofhighyieldshortstemricevarietiesdevelopedbythe

InternationalRiceResearchInstitute,andofmechanizedharvesting,whichhasbecomepopularsincethe1990s(Molleetal.1999).
Thisco‐existencefinallydisappearedinthelate1990s.Theproductivitydifferencebetweenfloatingriceandhighyieldvarietiesandtheneedformechanizationduetolaborshortagesstronglypromotedthetransformationofthedeep‐waterpaddyfieldsintoshallowerones.Thiswasmadepossiblebytheirrigationdepartment’scontinuousefforttoconstructsmallersluicegateswithineachtract.Thoseminorsluicegatesenableddetailedwatercontrolandthusensuredthatwaterlevelswithinatractcouldbekeptnearlyconstant.Yet,itwasfarmersratherthantheirrigationdepartmentthatinitiatedthischangeinwatermanagement.Inthemid1995s,villageleadersintheupperdeltaformedanalliancetorequesttheirrigationofficetoinstallanewwatermanagementpolicythatkeptwaterlevelsevenly,sothateveryonewouldbeabletousehighyieldvarietiesandharvesters.Afterthesuccessfulpetitionandsubsequenttransformationofthelowlands,thisnewpracticespreadtoirrigationofficesalloverthedeltaandsignificantlytransformedthedelta’sagriculturallandscape(MolleandKeawkuladya1998).
CoexistingInfrastructures
Thetransformationofthelandscapeseemedcompletedbytheturnofthecentury.However,thesuccessivefloodyearsof2006,2008and2011revealedthattheshifthasnotyetcompletedandmaybeneverwillbe.In2006,thefirstyearinwhichmassivefloodingoccurred,theRoyalIrrigationDepartmentandtheKingwereforcedtodivertwaterintoafewlow‐layingtractsintheAyutthayaProvinceinordertopreventfloodinginBangkok.Atfirst,theKingorderedtheirrigationdepartmenttodivertwaterintohisprivateproperty.ItbecameashallowbutvastretentionpondusedtostoreexcesswaterfromtheChaoPhrayaRiver.Afewdayslater,theRoyalIrrigationDepartmentpubliclyannouncedthecallfor“volunteers”whowouldtakeinspirationfromtheKingandoffertheirlandtoretainexcesswater.However,severalfarmerswitnessedthatsoonafterthecallforvolunteersthedepartmentdivertedwatertolowlayinglandsintheseareaswithoutsufficientcaution.Onefarmersaid,soonafterhewasinformedabouttheplanthedepartmentdivertedwaterduringthenight,andhefoundhimselfsurroundedbywaterwhenhegotupnextmorning(Lebel2009).
