Izixhobo zabo yilaser beams, iinqwelomoya kunye nesoftware yekhompyuter - endaweni yeekhampasi, iinqanawa zomthi kunye nesikhumba.



Kodwa ngaphezu kweminyaka engama-400 emva kokuba abahloli bamazwe abanjengoMhlekazi uFrancis Drake kunye noSebastian Vizcaino benze ezinye zeemephu zokuqala zonxweme lwaseKhalifoniya olunomtsalane, izazinzulu zeli lizwe kunye nezomdibaniso ziqalisa iprojekthi entsha yokwakha eyona mephu ineenkcukacha yonxweme lwaseKhalifoniya yakha yadityaniswa.

Iinzame ezixabisa i-3.3 yezigidi zeerandi ziyakuqala ngabaphandi kwinqwelomoya ebhabhela ngapha nangapha ngaselunxwemeni bedubula amawaka eentsimbi zelaser ngomzuzwana ematyeni, kumanxweme nasemaweni ngakunxweme lweemayile eziziikhilomitha ezili-1,200 ukusuka eMexico ukuya eOregon, bevelisa i3-D eneenkcukacha ezininzi. imifanekiso yeekhonto zomhlaba kwiifayile ezinkulu zekhompyuter.





Sifuna ingqiqo engcono yento ekhoyo. Sifuna imaphu yanamhlanje. Kwaye ngemephu yale mihla siya kuba nolwazi lokwenza izigqibo ezingcono, utshilo uDoug George, umphathi weprojekthi kunye neBhunga loKhuseleko lwe-Ocean, i-arhente karhulumente e-Oakland eyamkele i-2.75 yezigidi zeedola kwiprojekthi kwinyanga ephelileyo.

Imifanekiso iya kuba bukhali kakhulu imephu kufuneka ikwazi ukubona amatye kunye neepali zomnxeba, utshilo uGeorge. Idatha iya kubonelela ngesiseko sokulinganisa yonke into ukusuka kwimpembelelo yokunyuka kweelwandle kwiminyaka emashumi ezayo, ukukhukuliseka kweelwandle, ukuya kwingozi yezikhukhula ezivela kwizivunguvungu ezinkulu zasebusika.



Umsebenzi wemephu, olawulwa yi-National Oceanic and Atmospheric Administration, uya kuqala kwinyanga ezayo kwaye kulindeleke ukuba ugqitywe ngoDisemba, kunye nemifanekiso efakwe kwi-Intanethi ngehlobo elizayo.

Kufuneka indawo yokuqala



Ukutyhubela amashumi eminyaka, bekukho iiseti zeefoto ezininzi ezineenkcukacha kunye neemephu eziveliswe kumacandelo onxweme. Kodwa akukho mephu enye, enesisombululo esiphezulu sonxweme olupheleleyo lwaseCalifornia oluveliswe ngaxeshanye kusetyenziswa imigangatho efanayo.

Isiseko sisiqwenga esibalulekileyo. Awukwazi ukubeka esweni nantoni na ukuba awunayo isiqalo esihle-kwaye asinayo isiqalo esihle, utshilo uSam Johnson, isazi sejoloji yophando esisebenza kule projekthi kunye ne-US Geological Survey eSanta Cruz.



Ngaphandle kokufunda ukhukuliseko kunye nokunyuka komgangatho wolwandle, imifanekiso nayo iya kusetyenziswa zii-arhente ezifana neKomishoni yoNxweme lwaseCalifornia, iipaki zombuso, okanye izixeko ukucwangcisa ukubuyiselwa komhlaba omanzi, ulawulo lwezikhukhula, ulawulo lwamanzi esiphango, ukufikelela okungcono koluntu kumalwandle kunye nophuhliso lonxweme.

Rhoqo emva kweminyaka embalwa, izaqhwithi ezinamandla zibangela ukuba amawa adilike kwiindawo ezifana nePacifia, iCapitola neGoleta. Iilwandle eSan Diego kunye neOrange County ziyahlamba. Ulwazi olungcono lunokunceda ukubeka phambili iiprojekthi kwezo ndawo, abaxhasi bomzamo wemephu bathi.



Unxweme lwaseCalifornia lugqithise utshintsho olukhulu kule minyaka iyi-150 idlulileyo. Iilwandle ziyadilika kwaye zikhule, i-bluffs iyawa, utshilo uJohnson. Yonke indawo yahlukile. Unokuphulukana ne-20 yeemitha zonxweme kwiminyaka engama-50, okanye inokwenzeka ngaxeshanye.

Izixhobo zobuchwephesha obuphezulu ezisetyenzisiweyo kwimephu inokuba zivelise itikiti lakho lokugqibela lesantya.

Eyaziwa ngokuba yi-Light Detecting kunye ne-Ranging, okanye i-LiDAR, itekhnoloji iyafana naleyo isetyenziswa ngamapolisa ukubamba abakhawulezileyo. Abaphandi badubula ukukhanya okungeyongozi kwinqwelo-moya, kwaye imifanekiso yenziwa ngokubala ubungakanani bexesha elithathwa yi-pulse ukushiya inqwelomoya, ukuya emhlabeni nokubuyela kwizinzwa.

Indawo nganye yedatha inobude, ubude kunye nokuphakama. Kwaye apho iimephu ezininzi zesathelayithi zinokuba nedatha enye rhoqo ngeenyawo ezili-100, imifanekiso ye-LiDAR inokubonelela ngenqaku ledatha enye rhoqo ngeenyawo ezi-3 okanye ngaphantsi.

Umgangatho wolwandle ukuya emhlabeni

Ukongeza kunxweme, iprojekthi iya kuthatha imifanekiso yeSan Francisco Bay.

Oku kupholile ngokupheleleyo. Ndinomfanekiso eludongeni lwam lwemephu ye-1770s yaseSan Francisco Bay. Kubonakala ngathi iziphumo ze-x-ray ye-digestive digestive tract, utshilo u-Will Travis, umlawuli olawulayo weKomishoni yoLondolozo noPhuhliso lweBay, i-arhente karhulumente elawula uphuhliso olujikeleze i-bay.

Kodwa ngokwembono ababenayo, ngaphandle kokufota emoyeni, yayisengqiqweni kakhulu. Ujonga laa ecaleni kwemephu ye-USGS, kwaye ubona ukuba ichaneke kangakanani kwaye iyinyani. Oku kukusa kwisizukulwana esilandelayo.

Ulwandle sele lonyuke ngee-intshi ezisi-8 kule minyaka ili-100 idlulileyo, njengoko kulinganiswe ngeegeyiji zolwandle eFort Point eSan Francisco. Iimodeli zekhompyuter eziqhutywa yi-Scripps Institution of Oceanography, i-US Geological Survey kunye namanye amaziko ophando aqikelela kwinqanaba langoku lokufudumala kwehlabathi, inqanaba lolwandle linokuphakama elinye i-intshi ezingama-55 - okanye phantse iinyawo ezintlanu - ekupheleni kwale nkulungwane njengoko amashiti omkhenkce eqhubeka. ukunyibilika kwaye amanzi olwandle afudumeleyo anda.

Imiqadi ye-laser ye-infrared ayingeni emanzini kakuhle. Ke abaphandi banethemba lokudibanisa yonke imifanekiso evela emhlabeni, eya kunwebeka emanzini ukuya kwiimitha ezingama-30 ukuphakama, kunye nezinye iiseti zemifanekiso ye-sonar yomgangatho wolwandle apho i-USGS, i-NOAA kunye neCal State iMonterey Bay beziqokelela kwiinqanawa ukusukela oko. 2005.

Injongo yethu kukuba nemephu yomhlaba kunye nolwandle engenamthungo, utshilo uGeorge. Leyo yigrail engcwele wonke umntu ujonge ukunceda ngophando lokunyuka kolwandle, iitsunami, zonke iintlobo zomsebenzi.

Iziphumo zingasetyenziselwa ukufumanisa indawo yokwakhiwa kweendonga zolwandle, okanye ukwandisa imigxobhozo ukunciphisa izikhukhula, okanye indawo yokuqhubela phambili uphuhliso olukhoyo.

Inyathelo elilandelayo esifuna ukulenza kuvavanyo lobuthathaka bezixhobo ezahlukeneyo zokunyuka komgangatho wolwandle - iinqwelomoya zeenqwelomoya, iSilicon Valley, i-Embarcadero eSan Francisco, iTreasure Island, utshilo uTravis. Kwaye awukwazi ukwenza oko ngaphandle kokuba uyazi ubude bayo yonke into.
