Paragraph2 Professor: Okay,todaywe’regoingtodiscussthefourmajortypesofdrainagepatterns.Itrustyou’vealreadyreadthechaptersoyou’llrecallthatadrainagepatternisthearrangementofchannelsthatcarrywaterinanarea.Andthesepatternscanbeverydistinctivesincethey’redeterminedbytheclimate,thetopography,andthecompositionoftherockthatunderliestheformations。

So,consequently,wecanseethatadrainagepatternisreallyagoodvisualsummaryofthecharacteristicsofaparticularregion,bothgeologicallyandclimactically.Inotherwords,whenwelookatdrainagepatterns,wecandrawconclusionsaboutthestructuralformationandreliefofthelandaswellastheclimate.Nowalldrainagesystemsarecomposedofaninterconnectednetworkofstreams。

Asyoucansee,it’ssimilartomanysystemsinnature.Inadditiontothestructureofatree,italsoresemblesthehumancirculationsystem.Thisisaveryefficientdrainagesystembecausetheoveralllengthofanyonebranchisfairlyshort,andtherearemanybranches,sothatallowsthewatertoflowquicklyandefficientlyfromthesourceorsources.Okay。

let’slookatthenextexample.Thisdrainagepatternisreferredtoasaradialpattern.Noticehowthestreamsflowfromacentralpoint.Thisisusuallyahighmountain,oravolcano.Itkindoflookslikethespokesthatradiateoutfromthehubofawheel.Whenweseearadialpattern,weknowthattheareahasexperiencedupliftandthatthedirectionofthedrainageisdowntheslopesofarelativelyisolatedcentralpoint。
