I-NRCS Idaho ihlose ukuhlomisa izindawo eziningi ze-SNOTEL ngezinzwa zomswakama wenhlabathi

Izinhlelo zokugcina zihlomisa zonke iziteshi ze-telemetry ze-snowpack e-Idaho ukuze zilinganise umswakama wenhlabathi zingasiza ababikezeli bokutholakala kwamanzi kanye nabalimi.
I-USDA's Natural Resources Conservation Service isebenzisa iziteshi ze-SNOTEL ezigcwele ezingu-118 ezithatha izilinganiso ezizenzakalelayo zemvula eqongelelekile, okulingana namanzi eqhwa, ukujula kweqhwa kanye nokushisa komoya. Ezinye eziyisikhombisa azinazo izinsiza eziningi, zithatha izinhlobo ezimbalwa zokulinganisa.
Umswakama womhlabathi uthinta ukusebenza kahle kokugeleza kwamanzi ngoba amanzi aya emhlabathini lapho kudingeka khona ngaphambi kokuba adlulele emifuleni nasemadamini.
Ingxenye yeziteshi ze-SNOTEL ezigcwele zesifundazwe zinezinzwa noma ama-probe okuswakama komhlabathi, alandelela izinga lokushisa kanye nephesenti lokugcwala ekujuleni okuningana.
Idatha “isisiza ukuqonda nokuphatha imithombo yamanzi ngempumelelo enkulu” futhi yazisa “irekhodi ledatha elibalulekile esithemba ukuthi lizoba wusizo kakhulu njengoba siqoqa idatha eyengeziwe,” kusho uDanny Tappa, umphathi wocwaningo lweqhwa lwe-NRCS Idaho eBoise.
Ukunikeza zonke izindawo ze-SNOTEL esifundazweni ukukala umswakama wenhlabathi kuyinto eza kuqala isikhathi eside, esho.
Isikhathi salo msebenzi sincike ekuxhasweni ngezimali, kusho uTappa. Ukufaka iziteshi noma izinzwa ezintsha, ukuthuthukisa izinhlelo zokuxhumana zibe ubuchwepheshe beselula kanye nesathelayithi, kanye nokugcinwa okuvamile kube yizidingo eziphuthumayo muva nje.
“Siyaqaphela ukuthi umswakama womhlabathi uyingxenye ebalulekile yesabelomali samanzi, kanye nokugeleza kwamanzi ekugcineni,” esho.
“Siyazi ukuthi kunezindawo ezithile lapho ukusebenzisana komswakama wenhlabathi nokugeleza kwamanzi kubalulekile khona,” kusho uTappa.
Uhlelo lwe-SNOTEL lwase-Idaho luzozuza uma zonke iziteshi zihlonyiswe ngamathuluzi okuswakama komhlabathi, kusho uShawn Nield, usosayensi womhlabathi wesifundazwe se-NRCS. Okungcono kakhulu, abasebenzi bokuhlola iqhwa bazoba nososayensi womhlabathi ozinikele obhekene nohlelo kanye nerekhodi lalo ledatha.
Ukunemba kokubikezela kokuhamba komoya kuthuthuke cishe ngo-8% lapho kwakusetshenziswa khona izinzwa zomswakama nenhlabathi, esho, ecaphuna ucwaningo olwenziwe ngososayensi bamanzi kanye nabasebenzi baseyunivesithi e-Utah, e-Idaho nase-Oregon.
Njengoba azi ukuthi iphrofayili yomhlabathi yaneliswa kangakanani, uNield uthe “Ngokuvamile, sizwa ngabalimi abasebenzisa izinzwa zomswakama womhlabathi ukuze baphathe kahle amanzi okunisela,” kusho yena. Izinzuzo ezingenzeka zivela ekusetshenzisweni kwamaphampu amancane - ngaleyo ndlela kusetshenziswa ugesi namanzi amancane - okuhlanganisa umthamo nezidingo ezithile zezitshalo, kanye nokunciphisa ingozi yokuthi imishini yasepulazini ibhajwe odakeni.
