IDeltas kunye namachweba echweba, athe axhaphake kuSingasiqithi we-Iberia, anegalelo kuluhlu olwahlukeneyo lwendalo. Ezi ndawo zibaluleke kakhulu ngokwendalo eyohlukeneyo kwaye zisebenza njengeendawo zokuhlala ezibalulekileyo kwintaphane yezityalo nezilwanyana. Abantu abaninzi abazi kakuhle ukuba yintoni na umahluko phakathi kwamachweba kunye nedeltas.
Ke ngoko, kweli nqaku siza kukuxelela ukuba yintoni umahluko ophambili phakathi kwamachweba kunye ne-deltas, kunye neempawu kunye nokubaluleka kwazo.
Yintoni idelta
Ekudibaneni komlambo nolwandle, ukwakheka komhlaba okwaziwa ngokuba yidelta kuvela. Olu phawu lukhethekileyo lwejografi luphawulwa ngomxube wamanzi amatsha kunye namanzi anetyuwa. Ukuchuma kwale mimandla akunakulinganiswa nanto, njengoko intlenga ehanjiswa ngumlambo ifakwa kwi-delta, nto leyo ebangela umhlaba otyebileyo ngezondlo. Ngenxa yoko, Ezi deltas ziba zii-ikhosistim ezikhulayo ezixhasa iindidi ezahlukeneyo zobomi.
Umntla-mpuma weSpain likhaya le-Ebro River delta eyaziwayo, ebonakala njengenye yezona delta ezinkulu kunye nezona zihlukeneyo eYurophu. Le delta ibanzi ilikhaya kuluhlu olubanzi lweentaka, iintlanzi kunye neentlobo zezityalo. Ukongeza, isebenza njengendawo ebalulekileyo yokumisa kunye nendawo yokutya kwiintaka ezifudukayo ezilandela indlela yeAtlantiki neMeditera.
yintoni ichweba
Ngokwahlukileyo koko, amachweba yimimandla apho amanzi amatsha asuka emlanjeni axutywa namanzi anetyuwa asuka elwandle, nangona kumlinganiselo ongaphantsi kune-delta. Ezi ndawo zibonisa ukuguquguquka okubalulekileyo kwityuwa kwaye zibonelela ngeendawo zokuhlala ezifanelekileyo uluhlu olubanzi lwezidalwa zasemanzini, kubandakanywa iintlanzi, ii-crustaceans kunye ne-mollusks.
Ifumaneka kwingingqi ekumazantsi ntshona eSpain, ichweba loMlambo iGuadalquivir lamkelwa kuSingasiqithi we-Iberia. Ikwindawo ebalaseleyo njengelinye lawona machweba abalulekileyo elizwe, ibonelela ngendawo yokugcina iintlobo ezininzi zeentaka zasemanzini, ezibandakanya iiflamingo, iingqumba kunye nee<em>osprey. Ngaphaya koko, eli chweba lidlala indima ebalulekileyo ukulondolozwa kwezilwanyana zasendle ezisengozini yokuphela, ngakumbi ilynx yaseIberia.
Ukutyebisa i-ecosystem, zombini iideltas namachweba, zibonelela ngothotho lweenkonzo eziyimfuneko zokusingqongileyo. Oku kuquka ukuhluzwa kwamanzi, uthintelo lwezandyondyo, ukuzinziswa konxweme kunye nokuveliswa kokutya. Ukongeza, banexabiso elibalulekileyo lemfundo, isayensi kunye nabakhenkethi.
Ukuphila kwezi nkqubo ze-ecosystem kuhlala kusongelwa zizinto ezahlukeneyo, kubandakanywa ukusetyenziswa ngokugqithisileyo kwe ubutyebi bendalo, ungcoliseko, uphuhliso lwedolophu olungalawulwayo kunye neempembelelo zokutshintsha kwemozulu. Ukuqinisekisa ubukho bayo obuqhubekayo, kubalulekile ukubeka phambili ukugcinwa kwayo kunye nokwamkela izenzo zolawulo oluzinzileyo.
Ukubaluleka kweedeltas
I-delta yindawo ekusingwa kuyo ene-ecosystem ekhethekileyo. Ifumaneka emlonyeni womlambo, le ndawo yokuhlala yendalo likhaya leentlobo ngeentlobo zezityalo nezilwanyana. ukudala iparadesi yokwenyani kwabo bathanda indalo nabathanda izinto ezahlukahlukeneyo eziphilayo.
Ubuninzi bemithombo yendalo yeDelta kunye nesibongozo esihle sichaza ubuni bayo obukhethekileyo. Ngaphakathi kwemigxobhozo yayo emikhulu, amachibi kunye nemigxobhozo, iintlobo ezininzi zeentaka zasemanzini zikhula kakuhle, kuquka i-flamingo, i-herons kunye namadada, ukufumana induduzo kule ndawo yokuhlala ebonelela ngeendawo ezifanelekileyo zokuhlala kunye nokutya.
I-delta ayiyondawo yokuhlala yeentaka kuphela, kodwa Ikwalikhaya leentlobo ngeentlobo zezilwanyana ezanyisayo, ezirhubuluzayo kunye nezilwanyana ezihlala emanzini. Olunye uhlobo oluphawulekayo yingwenya edla ngokubonwa igcakamele ilanga kwiindonga zemilambo okanye ibhabha kamnandi phakathi kwezityalo zasemanzini. Ukongeza, i-delta likhaya lee-otter ezidlalayo kunye nobukho obunomtsalane be-capybaras, zombini bonwabela amanzi e-delta.
Okuphawuleka ngokulinganayo kukwahlukana kwezityalo okufumaneka ngaphakathi kwidelta. Imithi ye<em>mangrove ebanzi, ephawulwa ziingcambu zayo ezintsonkothileyo, inceda ekudaleni umhlaba owahlukileyo lo gama inika ikhusi kwinkitha yezidalwa zaselwandle. Ukongeza, ubukho bamahlathi esundu kunye namatyholo bukhuthaza indawo yokuhlala efanelekileyo yezilwanyana zasendle zasekuhlaleni, ukunika ukutya kunye nomthunzi kubemi be-delta.
Kukwakho nokhenketho kwi-deltas. Abakhenkethi abaya kwi-delta banokuhamba-hamba kwiindlela kunye neendlela okanye bangene kuhambo lwesikhephe. Olu hambo lwesikhephe lujolise ekungeneni kuthungelwano oluntsonkothileyo lwemisele namachibi. Ngale ndlela, ezinye zexabiso lokulondolozwa kwezi ndawo kunye nokubaluleka kwazo zihanjiswa.
Amaziko amaninzi anikezela iinzame zawo zokukhusela le nkqubo yahlukileyo yendalo, eqinisekisa ubomi bayo obude. Ngaphaya koko, ukukhuthaza ukhenketho oluzinzileyo kuvumela abantu ukuba bonwabele ubukhazikhazi bedelta ngaphandle kokubeka esichengeni indalo yayo eethe-ethe.
Umahluko ophambili phakathi kwamachweba kunye ne-deltas
Xa sithetha ngeempawu zejografi ezinxulumene nokudibana kwemilambo kunye nolwandle, amachweba kunye needelta zihlala zibhidekile. Nangona zombini ziyinxalenye yomlambo, kukho ukungafani okuphawulekayo phakathi kolu kwakheka.
Xa umlambo uthutha intlenga kwaye uyibeke emlonyeni wawo, imbonakalo yejografi eyaziwa ngokuba yidelta iye yenziwa. Lo mmandla unxantathu, ubonakala ngokuba mcaba, likhaya lemijelo emininzi yemilambo enqumla imbonakalo-mhlaba. IiDeltas zidume ngobuninzi bazo bezondlo, nto leyo ezenza amaziko ohlukeneyo obomi basemanzini. Iideltas eziphawulekayo ziquka i-Nayile Delta e-Egypt kunye ne-Mekong Delta e-Vietnam.
Ngokuchaseneyo noko, ichweba yimbonakalo yejografi eyenziwe kukuhlangana kwamanzi anetyuwa elwandle kunye namanzi amatsha aphuma emlanjeni xa efika emlonyeni wawo. Lo mxube wamanzi uvelisa indawo yokuhlala eyahlukileyo eneempawu zayo ezizodwa. Amachweba, leyo Ngokuqhelekileyo bathatha imilo yefuneli, baxhomekeke ekunqandeni kunye nokuhamba kwamaza, okubangela ukuguquguquka kwetyuwa emanzini.. Kwezi zinto ziphilayo, iintlobo ngeentlobo zezinto eziphilayo zifumana ikhaya lazo, kuquka iintaka, iintlanzi noonokrwece. Imizekelo ebalaseleyo yamachweba iquka ichweba leVigo eGalicia, eSpain kunye neChesapeake Bay eMelika.
Njengoko ubona, ezi yantlukwano zidla ngokubhidaniswa akukho nzima kangako ukuzikhumbula. Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nomahluko phakathi kwamachweba kunye ne-deltas.
