singazivimbela kanjani izikhukhula zemifula?
Context:Izinhlelo ezivelele zamadamu ziye zakhiwa eceleni koMfula iMississippi noMfula iSacramento e-United States, kanye nePo, iRhine, uMfula iMeuse, iRhone, iLoire, iVistula, i-delta eyakhiwe yiRhine, iMaas / Meuse neScheldt eNetherlands kanye neDanube eYurophu. Ngesikhathi soMbuso WamaShayina Olwayo, uhlelo lokunisela iDujiangyan lwakhiwa yiQin njengohlelo lokonga amanzi nokulawula izikhukhula. Ingqalasizinda yesistimu itholakala eMinjiang (Chinese; pinyin), okuyi- umfula omude kunayo yonke weChang Jiang, eSichuan, eChina.  Uhlelo lwamachibi aseMississippi lungenye yezinhlelo ezinkulu kunazo zonke ezitholakala emhlabeni. Ihlanganisa amakhilomitha angaphezu kuka-5 600 (3,500 mi) amachibi anwebeka cishe amakhilomitha ayi-1 000 (620 mi) ngaseMississippi, kusukela eCape Girardeau, eMissouri, kuya eMississippi delta. Zaqalwa abahlali baseFrance eLouisiana ngekhulu le-18 ukuze bavikele idolobha laseNew Orleans. Izindonga zokuqala zaseLouisiana zazingaba ngu-90 cm (3 ft) ukuphakama futhi zahlanganisa ibanga elingamakhilomitha angu-80 (50 mi) osebeni lomfula. I - U.S. Army Corps of Engineers, ngokubambisana ne - Mississippi River Commission, yanweba uhlelo lwamachibi kusukela ngo - 1882 ukuze luhlanganise imifula esuka eCairo, e - Illinois kuya emlonyeni we - Mississippi delta eLouisiana. Maphakathi nawo-1980, base befinyelele ezingeni labo lamanje futhi babebalelwa ku-7.3 m (24 ft) ukuphakama; amanye amachibi aseMississippi aphakeme njenge-15 m (50 ft). Amachibi aseMississippi futhi ahlanganisa amanye amachibi aqhubekayo ahamba isikhathi eside kunawo wonke emhlabeni. Omunye umhosha onjalo unqamula ngaseningizimu usuka ePine Bluff, e-Arkansas, ibanga elingamakhilomitha angaba ngu-610. Ubukhulu nezinga lezindonga zaseMississippi ngokuvamile kuye kwaqhathaniswa noDonga Olukhulu LwaseChina.  I-United States Army Corps of Engineers (USACE) incoma futhi isekela ubuchwepheshe bokuvalelwa kwamaselula (ama-geocells) njengendlela engcono kakhulu yokuphatha. Ukunakwa okukhethekile kunikezwa endabeni yokuguguleka kwendawo, ukuvimbela ukweqisa kanye nokuvikelwa kwe-dike crest kanye ne-slope ezansi. Ukuqiniswa ngama-geocells kunikeza amandla okudonsa enhlabathini ukuze amelane kangcono nokungazinzi.  Amachibi okwenziwa angadala ukukhuphuka komgodi womfula wemvelo ngokuhamba kwesikhathi; ukuthi lokhu kuyenzeka noma cha nokuthi kwenzeka ngokushesha kangakanani, kuncike ezintweni ezahlukahlukene, enye yazo inani nohlobo lomthwalo womgodi womfula. Imifula enezikhukhula ezinokuqongelela okukhulu kwenhlabathi ithambekele kulokhu kuziphatha. Izibonelo zemifula lapho amachibi okufakelwa aholela ekukhuphukeni kombhede womfula, kuze kube seqophelweni lapho umbhede womfula uphakeme kunendawo yomhlaba eseduze ngemuva kwamachibi, atholakala eMfuleni ophuzi eChina naseMississippi e-United States.
Kuye kwakhiwa amachibi abalulekile ukuze kulondolozwe amanzi futhi kunqandwe izikhukhula. UMfula iMississippi noMfula iSacramento e-United States, kanye noMfula iPo, iRhine, uMfula iMuse, iRhone, iLoire, iVistula, i-delta eyakhiwa yiRhine, iMaas/Meuse neScheldt eNetherlands kanye neDanube eYurophu. Uhlelo lwezindonga zaseMississippi lungenye yezinhlelo ezinkulu kunazo zonke emhlabeni
