I-GLEN CANYON, E-ARIZONA – Njengoba iNtshonalanga ye-United States ibhekene nobunzima obukhulu bemvula, wonke amaconsi amanzi abalulekile. Esinyathelweni esibalulekile sokuphathwa kwamanzi okunembile, i-US Geological Survey (USGS), ngokubambisana neziphathimandla zamanzi zikahulumeni, imemezele ukuthunyelwa ngempumelelo kohlelo lokuqapha ukugeleza kwamanzi oluthuthukisiwe oluvela eDamini laseGlen Canyon eMfuleni iColorado. Lokhu kuthunyelwa kuphawula inkathi entsha yokuqoqwa kwedatha ngesikhathi sangempela, okunembile kakhulu kwenye yezinhlelo zemifula ezibaluleke kakhulu eMelika.
Inselele: Ukulinganisa Okunembile Emgqeni Wokuphila Obalulekile
UMfula iColorado “uyindlela yokuphila,” ohlinzeka ngamanzi kwezolimo kanye namashumi ezigidi zabantu ezifundazweni eziyisikhombisa zase-US naseMexico. Isomiso esiqhubekayo sibangele ukuthi amazinga amanzi emathangini ayo amakhulu, iLake Powell neLake Mead, ehle. Ukulinganisa nokuphatha ngokunembile yonke imitha yamanzi ekhishwa ngaphansi komfula kube yinkinga eyinhloko emnothweni wesifunda kanye nokuzinza.
Ingxenye yomfula engezansi kweDamu laseGlen Canyon iphawuleka ngamanzi ahamba ngokushesha futhi avunguzayo, okwenza izindlela zokulinganisa ukugeleza ezisekelwe ekuthinteni kwendabuko zingagcini nje ngokuba yingozi kochwepheshe kodwa futhi kube nzima ukuzisebenzisa ngesikhathi semicimbi emikhulu yamanzi. Lokhu ngaphambilini kwaholela ezikhaleni nasekulibazisekeni kwedatha ngezikhathi ezibucayi kakhulu.
Isixazululo: Ukuqapha i-Radar Ekude, Eqhubekayo, Nenembile Kakhulu
Imitha yokugeleza yerada engathintani esanda kusetshenziswa (njengemodeli evela ku-SENIX noma eValeport) ifakwe ngokuphephile ebhulohweni elingezansi kwedamu. Isebenza ngokukhipha amagagasi erada aye ebusweni bomfula nokuhlaziya isignali eboniswayo kusetshenziswa umphumela we-Doppler ukubala ijubane lobuso ngaphandle kokuthintana namanzi ngokomzimba.
“Lolu hlelo lusebenza njengomlindi wamanzi osebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto,” kuchaza unjiniyela wensimu ye-USGS. “Luqeda ngokuphelele ingozi yokuthi izinzwa zibhujiswe yizikhukhula noma imfucumfucu. Okubaluleke kakhulu, ngesikhathi sezikhukhula—lapho umfula uyingozi kakhulu futhi idatha ibaluleke kakhulu—ochwepheshe bethu bangaqoqa ulwazi olubalulekile lwejubane ekuphepheni kwebhuloho noma ngisho kude.”
Ukuhlanganiswa Kwesistimu kanye Nokusetshenziswa Kwedatha
Imitha yokugeleza kwe-radar ihlanganiswe nezingxenye eziningana ezibalulekile:
- I-GPRS/4G Wireless Transmitter: Ithumela idatha yejubane ngesikhathi sangempela ngokushesha ku-USGS National Water Information System kanye nezikhungo zokulawula zomnyango wamanzi wesifundazwe.
- I-Touchscreen Datalogger: Ivumela abasebenzi basensimini ukuthi babuke izitayela zedatha zesikhathi sangempela, balungiselele amapharamitha, futhi bathumele amalogi omlando ukuze kube lula ukuwalungisa nokulinganisa.
- Ukuqapha Amapharamitha Amaningi: Uhlelo luqapha izinga lamanzi ngasikhathi sinye, futhi luhlanganiswe nedatha yesigaba sesiteshi esilinganisiwe ngaphambilini, lubala ngokuzenzakalelayo ukukhishwa kwesikhathi sangempela.
Le datha isetshenziselwa ngqo:
- Ukuqinisekisa Ukukhishwa Kwedamu: Ukuhlola ngokunembile inani lamanzi akhishwa eDamini laseGlen Canyon ukuqinisekisa ukuhambisana nezivumelwano zokwabiwa kwamanzi phakathi kwezifundazwe ezingezansi komfula.
- Amamodeli Okuxwayisa Ngezikhukhula: Ukunikeza izikhathi ezinde zokuhola izixwayiso ngezikhukhula emiphakathini esezansi komfula.
- Izifundo Zokugeleza Kwemvelo: Ukusiza ososayensi ukuqonda umthelela wamazinga ahlukene okugeleza endaweni ezungezile, okunikeza idatha yokusekela izindawo zokuhlala zezinhlobo zezinhlanzi ezisengozini yokuqothulwa.
Umbono Wesikhathi Esizayo
Impumelelo yalo msebenzi inikeza imodeli yokuthuthukisa ubuchwepheshe bokuqapha ezindaweni ezibalulekile kulo lonke iColorado River Basin kanye nakulo lonke elase-United States. Iziphathimandla zemithombo yamanzi zihlela ukuqalisa lobu buchwepheshe be-radar obungenabo othintana nabo ezindaweni zokuqapha ezibaluleke kakhulu neziyingozi eminyakeni emihlanu ezayo.
“Lapho sibhekene nenselele yokushintsha kwesimo sezulu, kumelwe sisebenzise ubuchwepheshe obuhlakaniphile kakhulu ukuphatha imithombo yethu yemvelo eyigugu kakhulu,” kuphetha umholi wephrojekthi. “Lokhu kutshalwa kwezimali akugcini nje ngokuthuthukisa ikhwalithi yedatha kanye nokuphepha kwabasebenzi kodwa futhi kubeka isisekelo esiqinile sokuphepha kwamanzi esikhathini esizayo.”
Isethi ephelele yamaseva kanye ne-software engenantambo module, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
