Ekuthuthukisweni okukhulu kokuphathwa kwamanzi kwezolimo, ukusetshenziswa kwe-hydrological radar flowmeters kuveze imiphumela ethembisayo kuwo wonke amapulazi e-United States. Lawa madivayisi amasha, asebenzisa ubuchwepheshe be-radar ukukala ukugeleza kwamanzi, avele njengabashintshi bemidlalo kubalimi abalwela ukuthuthukisa ukusetshenziswa kwamanzi, ukuthuthukisa isivuno sezitshalo, kanye nokubhekana nezinselele ezibangelwa ukuguquka kwesimo sezulu.
Isikhathi Esisha Ekuphathweni Kokunisela
Ngokomlando, ukuphathwa kwamanzi kwezolimo kuye kwathembela ezinhlelweni zokulinganisa ukugeleza zendabuko ezivame ukungalungi futhi ezidinga umsebenzi omningi. Kodwa-ke, ama-flowmeter e-radar e-hydrologic anikeza indlela engangenisi ukungcola nenembe kakhulu yokulinganisa ukugeleza kwamanzi ngesikhathi sangempela ezinhlelweni zokunisela. Ngokusebenzisa ubuchwepheshe be-radar ye-microwave, lawa ma-flowmeter angaqapha ngempumelelo ukusetshenziswa kwamanzi emapayipini, eziteshini, nasemigodini ngaphandle kokudinga noma yiziphi izinguquko ezibonakalayo engqalasizinda ekhona.
Amaphrojekthi amaningana okuhlola kuzo zonke izifundazwe ezibalulekile zezolimo—eCalifornia, eTexas, naseNebraska—abonise ukuthi la madivayisi anganikeza abalimi idatha ebalulekile, okubenza bakwazi ukwenza izinqumo ezinolwazi mayelana nokusetshenziswa kwamanzi. Leli khono libaluleke kakhulu enkathini ephawulwa ukwanda kwezimo zesomiso nokukhathazeka ngokuntuleka kwamanzi.
Izindaba Zempumelelo Ezivela Kuwo Wonke Umhlaba
Abalimi abahlanganyela ezinhlelweni zokuhlola babike ukuthuthuka okukhulu emikhubeni yokuphathwa kwamanzi. E-Central Valley yaseCalifornia, ebhekene nezimo zesomiso esinzima, abalimi abasebenzisa ama-flowmeter e-radar yamanzi bathole ukwanda okungu-20% ekusebenzeni kahle kokunisela. Ngokuthola idatha yokugeleza enembile ngesikhathi sangempela, laba balimi bangalungisa amashejuli abo okunisela ngokwezidingo zezitshalo, banciphise ukulahlwa kwamanzi ngenkathi bekhulisa impilo yezitshalo.
ETexas, iqembu labalimi bekotoni lisebenzise ama-flowmeter e-radar ukuqapha ukusetshenziswa kwamanzi ngezikhathi zokukhula okuphezulu. Imiphumela yokuqala ikhombisa ukuthi abalimi banciphise ukusetshenziswa kwamanzi cishe ngo-15-25% ngenkathi begcina amazinga okukhiqiza. "Ukunemba kwalokhu kufundwa kusenza sibe namasu amaningi ngemikhuba yethu yokunisela. Kushintshe indlela esicabanga ngayo ngokusetshenziswa kwamanzi," kusho umlimi wendawo uMiguel Rodriguez.
Isifunda saseMidwest naso siwamukele lobu buchwepheshe, njengoba abalimi baseNebraska bebika izinzuzo ezinkulu. Ngokusetshenziswa kwe-radar flowmeters, ukusetshenziswa kwamanzi okujwayelekile ngesikhathi sezigaba zokukhula okubalulekile kwehle, ndawonye konga izigidi zamagaloni amanzi kuwo wonke amapulazi abambe iqhaza.
Umthelela Wezemvelo Nomnotho
Imiphumela yemvelo yokuthuthukisa imikhuba yokunisela ngama-hydrological radar flowmeters ijulile kakhulu. Ochwepheshe balinganisela ukuthi ukuphathwa kwamanzi okuthuthukisiwe kunganciphisa kakhulu ukugeleza kwamanzi kanye nokungcola kwezakhamzimba okuhambisana nakho okuthinta imigwaqo yamanzi kanye nezindawo zemvelo eziseduze.
Ngaphezu kwalokho, izinzuzo zomnotho zabalimi zinkulu kakhulu. Njengoba kunezindleko zamanzi eziphansi kanye nesivuno sezitshalo esithuthukisiwe, inzuzo yokutshalwa kwezimali kwabanye abalimi itholakale esikhathini esingaphansi konyaka. “Akukhona nje ukonga amanzi; kumayelana nokonga imali nokuqinisekisa ukuthi amapulazi ethu ayasebenza isikhathi eside,” kusho uLaura Thompson, isazi sezolimo e-United States Department of Agriculture (USDA).
Izinselele kanye namathemba esikhathi esizayo
Naphezu kwemiphumela emihle, ukwamukelwa kwe-hydrological radar flowmeters kubhekene nezinselele, okuhlanganisa izindleko zokuqala zokufakwa kanye nohlelo lokufunda oluhambisana nobuchwepheshe obusha. Abanye abalimi bazwakalisa ukungabaza ukushintsha izindlela zendabuko, kodwa labo abenze ushintsho babika ngokushesha ukuthi bayabona izinzuzo.
I-USDA kanye neminyango yezolimo kahulumeni bakhuthaza ngenkuthalo ukusetshenziswa kwama-flowmeter e-radar futhi bahlola izindlela zokuxhasa ukufakwa kwawo emapulazini amancane. Njengoba idatha eyengeziwe itholakala, kulindeleke ukuthi ukumela ukwamukelwa kabanzi kukhule.
Isiphetho
Ukusetshenziswa kwe-hydrological radar flowmeters kuphawula isikhathi esibalulekile ekufuneni imikhuba yezolimo esimeme e-United States. Njengoba abalimi bebhekene nezinselele ezimbili zokwandisa isivuno sezitshalo nokonga imithombo yamanzi, lobu buchwepheshe obusha bunamandla okuhola indlela eya ekusaseni lezolimo elisebenza kahle nelinobungani nemvelo. Ukubambisana okuqhubekayo phakathi kwabalimi, abacwaningi, kanye nabathuthukisi bezobuchwepheshe kuzoba yisihluthulelo ekusebenziseni amandla aphelele ale ntuthuko ethembisayo ekuphathweni kwamanzi ezolimo.
Ukuze uthole ulwazi olwengeziwe ngama-flowmeter e-radar e-hydrologic kanye nemikhuba yezolimo ezisimeme, vakashela iwebhusayithi esemthethweni ye-USDA noma uxhumane nehhovisi lakho lendawo lokwandisa ezolimo.
Ukuze uthole ulwazi olwengeziwe lwenzwa ye-radar yamanzi,
