Zvirongwa zvekuzopedzisira zvashongedza zviteshi zvesnowpack telemetry muIdaho kuyera hunyoro hwevhu zvinogona kubatsira vanofanotaura nezvekupa mvura nevarimi.
USDA's Natural Resources Conservation Service inoshandisa 118 yakazara SNOTEL zviteshi zvinotora otomatiki zviyero zvekunaya kwakaunganidzwa, mvura yechando-yakaenzana, kudzika kwechando uye tembiricha yemhepo.Zvimwe zvinomwe hazvina kunyanya kurongeka, zvichitora marudzi mashoma ezviyero.
Kunyorova kwevhu kunokanganisa kuyerera kwemvura inopinda muvhu painodiwa isati yaenda kuhova nemadhamu.
Hafu yenzvimbo izere SNOTEL zviteshi zvine ivhu-unyoro sensors kana probes, iyo inoteedzera tembiricha uye saturation muzana pakadzika akati wandei.
Iyo data "inotibatsira kunyatsonzwisisa uye kubata chitubu chemvura" uye kuzivisa "yakakosha data rekodhi yatinovimba kuti yakakosha zvakanyanya sezvo isu tichiunganidza data rakawanda," akadaro Danny Tappa, NRCS Idaho snow survey supervisor muBoise.
Kushongedza nzvimbo dzese dzeSNOTEL mudunhu kuti dziyere hunyoro hwevhu chinhu chakakosha kwenguva refu, akadaro.
Nguva yeprojekti inoenderana nemari, Tappa akadaro.Kuisa zviteshi zvitsva kana masensa, kusimudzira masisitimu ekutaurirana kune maserura uye setiraiti tekinoroji, uye kuchengetedza kwakawanda kwave kuri kudzvanya zvinodikanwa nguva pfupi yadarika.
"Tinoziva hunyoro hwevhu chikamu chakakosha chebhajeti remvura, uye pakupedzisira kuyerera," akadaro.
"Tinoziva kuti kune dzimwe nzvimbo uko kupindirana kwehunyoro hwevhu nekuyerera kwakakosha," Tappa akadaro.
Idaho's SNOTEL system yaizobatsira kana zviteshi zvese zvakashongedzerwa nevhu-unyoro zviridzwa, akadaro Shawn Nield, NRCS state ivhu sainzi.Zvakanaka, vashandi vekuongorora chando vaizove nesaenzi yakazvitsaurira yevhu ine chekuita nehurongwa uye rekodhi yayo yedata.
Streamflow kufanotaura kurongeka kwakagadziridzwa ne8% uko kwakashandiswa ma sensors evhu-unyoro, akadaro, achitsanangura tsvakiridzo yakaitwa nevanoongorora hydrologists uye vashandi veyunivhesiti muUtah, Idaho neOregon.
Nekuziva kuti ivhu rinogutswa zvakadii zvinobatsira varimi nevamwe, Nield akati “Nguva zhinji, tinonzwa nezvevarimi vachishandisa ma sensors evhu-unyoro kuitira kuchengetedza zvakanaka mvura yemadiridziro,” vakadaro.Mabhenefiti anotarisirwa kubva pakumhanyisa pombi shoma - nekudaro kushandisa magetsi uye mvura kushoma - kuenzanisa mavhoriyamu kune zvinodiwa nechirimwa, uye kuderedza njodzi yekuti midziyo yekurima inonamira mumadhaka.
