Isikhululo soMoya sase-El Toro Marine Corps e-Irvine, eCalifornia sakhiwa ngo-1942.Ikholvethi evulekileyo edibeneyo yakhiwa phezulu kwi-Agua Chinon Creek ukwenzela ukwakhiwa kweendlela zeenqwelo-moya kunye neendlela zokuncedisa ukusebenza kwesiseko.Isiseko emva koko sacinywa kwaye sathengiswa uphuhliso. Esi sicwangciso siquka ulwakhiwo lweziko elikhulu lokuhlala nelezemidlalo, ibala legalufa, kunye nezibonelelo nomhlaba ozinikele ekulungiseni umhlaba kunye nezolimo.Oku kuya kufuna isicwangciso sokujongana nokuhamba kwamanzi esiphango kuphuhliso lwexesha elizayo.
Icandelo eliphantsi elithambileyo le-Agua Chinon lingaphezulu kwe-intshi ye-intshi ezingama-3,000. Enye yeengxaki eziphambili iinjineli ezijongene nazo xa ziyila iprojekthi kukubonelela ngeendawo zokuhlala ngokwandisa indawo yomlambo ophantsi wendalo ngelixa unikezela ukhuseleko oluyimfuneko kwiziganeko zemvula. Ithambeka lendalo lomhlaba okhoyo udlula i-1.5%, engumnqantsa kakhulu ukugcina amazinga angakhukulisiyo.
Ngenxa yokuthintelwa kokusetyenziswa kwekhonkrithi, ukungafani komgangatho kunye nesidingo sokwandisa ufikelelo olusezantsi lwendalo, iinjineli ziye zayila inkqubo yokuhambisa amanzi yendalo esezantsi evulekileyo esebenzisa uthotho lwe-28 gabion drop structures. dala ithafa lezikhukula elahlukileyo kwaye udale uvakalelo lwendalo.Imiqukuqelo esetyenzisiweyo kuyilo ithathwe kwiSicwangciso esiHlaziyiweyo soLawulo lweZikhukhula loMlambo iSan Diego, esamisela iminyaka eli-100 yokuqukuqela ngokusekwe kulwazi oluqikelelweyo lokusebenzisa umhlaba kwixesha elizayo kunye nemigangatho yengingqi yokusetyenziswa kwamanzi. ithambeka elilelona lifanelekileyo ukuze uzinzo lube ngaphantsi kwe-0.5%.
Izakhiwo ze-gabion ecaleni kwe-Agua Chinon Creek ziye zavavanywa nguMama weNdalo.Ekuqaleni kuka-2018, i-Southern California ifumene isiganeko esiyimbali semvula esikhokelela kwizikhukula kunye nodaka oluphuma kulo lonke ilizwe.Isakhiwo se-gabion sibambe phezulu, sinciphisa ukuhamba kwamanzi kunye nokulawula ukhukuliseko kunye izikhukula.
Abasebenzi beStormwater Solutions bamema iingcali kushishino ukuba zonyule ezona zicinga ukuba zezona zibalaseleyo kwaye zivelisa iiprojekthi zamanzi kunye namanzi amdaka ukuze ziqwalaselwe kumba wonyaka weSikhokelo seReference.Zonke iiprojekthi kufuneka zibe zikwinqanaba loyilo okanye lokwakha kwiinyanga ezili-18 ezidlulileyo.
