I-NRCS Idaho ijonge ukuxhobisa iindawo ezininzi ze-SNOTEL ngeenzwa zokufuma komhlaba

Izicwangciso zokugqibela zokuxhobisa zonke izikhululo ze-telemetry ze-snowpack e-Idaho ukulinganisa ukufuma komhlaba zinokunceda ababikezeli bokufumaneka kwamanzi kunye nabalimi.
I-USDA's Natural Resources Conservation Service isebenzisa izikhululo ze-SNOTEL ezili-118 ezipheleleyo ezithatha imilinganiselo ezenzekelayo yemvula eqokelelweyo, i-snow-water elingana nayo, ubunzulu bekhephu kunye nobushushu bomoya. Ezinye ezisixhenxe azinazo iindlela ezininzi, zithatha iintlobo ezimbalwa zokulinganisa.
Ukufuma komhlaba kuchaphazela ukusebenza kakuhle kwamanzi agelezayo kuba amanzi aya emhlabeni apho kufuneka khona ngaphambi kokuba angene kwimifula nakwiindawo zokugcina amanzi.
Isiqingatha sezikhululo ze-SNOTEL ezipheleleyo zelizwe zinezixhobo zokuva umswakama womhlaba okanye iiprobe, ezilandelela ubushushu kunye nepesenti yokwanda kobushushu kubunzulu obahlukeneyo.
Idatha “isinceda siqonde kwaye silawule imithombo yamanzi ngokufanelekileyo” kwaye isinika ulwazi “ngengxelo ebalulekileyo yedatha esinethemba lokuba iya kuba luncedo ngakumbi njengoko siqokelela idatha engaphezulu,” utshilo uDanny Tappa, umphathi wophando lwekhephu lwe-NRCS Idaho eBoise.
Ukunika zonke iindawo ze-SNOTEL kurhulumente ukulinganisa ukufuma komhlaba yinto ephambili kwixesha elide, utshilo.
Ixesha leprojekthi lixhomekeke kwinkxaso-mali, utshilo uTappa. Ukufakela izitishi ezintsha okanye iisensa, ukuphucula iinkqubo zonxibelelwano ukuya kwitekhnoloji yeselula neyesathelayithi, kunye nokugcinwa ngokubanzi kube ziimfuno ezingxamisekileyo kutshanje.
“Siyaqonda ukuba ukufuma komhlaba yinxalenye ebalulekileyo yebhajethi yamanzi, kunye nokuhamba kwamanzi ekugqibeleni,” utshilo.
“Siyazi ukuba kukho iindawo ezithile apho ukusebenzisana kokufuma komhlaba kunye nokuhamba kwamanzi kubalulekile,” utshilo uTappa.
Inkqubo ye-SNOTEL yase-Idaho ingancedakala ukuba zonke izikhululo zinezixhobo zokufuma komhlaba, utshilo uShawn Nield, isazinzulu somhlaba sikarhulumente we-NRCS. Okona kulungileyo kukuba, abasebenzi abahlola ikhephu babe nesazinzulu somhlaba esizinikeleyo esinoxanduva lwenkqubo kunye nerekhodi yayo yedatha.
Ukuchaneka kwengqikelelo ye-Streamflow kuphucuke malunga ne-8% apho kwakusetyenziswa khona izixhobo zokuva umswakama womhlaba, utshilo, ecaphula uphando olwenziwe ziingcali ze-hydrologists kunye nabasebenzi beyunivesithi e-Utah, e-Idaho nase-Oregon.
Esazi ukuba iprofayili yomhlaba yanelisekile kangakanani kwaye inceda abalimi nabanye, uNield uthe “Ngokufuthi, siva ngabalimi abasebenzisa izixhobo zokuva amanzi okufuma emhlabeni ukuze balawule kakuhle amanzi okunkcenkceshela,” utshilo. Iingenelo ezinokubakho ziquka ukusebenzisa iimpompo ezimbalwa - ngaloo ndlela kusetyenziswa umbane namanzi amancinci - ukulinganisa ubungakanani beemveliso neemfuno ezithile zezityalo, kunye nokunciphisa umngcipheko wokuba izixhobo zasefama zibhajwe eludakeni.
