Ukunisela ngenkasa kwezolimo kuyingxenye ebalulekile yemikhuba yezolimo yesimanje, okuqinisekisa ukuthi izitshalo zithola amanzi eziwadingayo ukuze zikhule kahle futhi zikhiqize. Kodwa-ke, ukuphathwa kwamanzi okuphumelelayo kuya ngokuya kuba yinto ebaluleke kakhulu ngenxa yezici ezifana nokushintsha kwesimo sezulu, ukushoda kwamanzi kanye nesidingo semikhuba yezolimo eqhubekayo. Kulesi simo, ubuchwepheshe bokulinganisa ukugeleza kwemisele evulekile ye-Doppler buba ithuluzi eliwusizo lokuthuthukisa ukunemba nokusebenza kahle kwezinhlelo zokunisela.
Ubuchwepheshe bokulinganisa ukugeleza kwesiteshi esivulekile se-Doppler busebenzisa umphumela we-Doppler ukulinganisa ngokunembile ukugeleza kwamanzi eziteshini ezivulekile njengemisele, imisele, kanye neziteshi zokunisela. Ngokukhipha izimpawu ze-ultrasonic emanzini agelezayo nokuhlaziya ukushintsha kwemvamisa yezibonakaliso eziboniswayo, amamitha okugeleza e-Doppler angabala ijubane kanye nesivinini sokugeleza kwamanzi ngokunemba okuphezulu. Lobu buchwepheshe bunikeza izinzuzo eziningana zokusetshenziswa kokunisela kwezolimo, ikakhulukazi maqondana nokwenza ngcono ukusetshenziswa kwamanzi kanye nokwandisa ukusebenza kahle okuphelele.
Enye yezinzuzo eziyinhloko zokulinganisa ukugeleza kwesiteshi esivulekile se-Doppler sokunisela kwezolimo yikhono lokunikeza idatha yokugeleza kwamanzi ngesikhathi sangempela. Ngokuqhubeka nokuqapha ukugeleza kwamanzi eziteshini zokunisela, abalimi nabaphathi bokunisela bangathola ukuqonda ngokusetshenziswa kwamanzi kanye nokusatshalaliswa kwawo ensimini. Le datha yesikhathi sangempela ivumela ukulawulwa okunembile kwezinhlelo zokunisela, okubavumela ukuthi bavumelane namazinga okugeleza kwangempela futhi baqinisekise ukuthi amanzi alethwa ezitshalweni ngenani elifanele ngesikhathi esifanele.
Ngaphezu kwalokho, amamitha okugeleza e-Doppler angasiza ekutholeni nasekuxazululeni izinkinga ezifana nokuvuza, ukuvaleka, noma ukusatshalaliswa kwamanzi okungasebenzi kahle ngaphakathi kweziteshi zokunisela. Ngokubona nokuxazulula lezi zinkinga ngokushesha, abalimi banganciphisa imfucuza yamanzi futhi baqinisekise ukuthi wonke amaconsi amanzi asetshenziswa ngempumelelo ekuniseleni izitshalo. Le ndlela yokuphatha ukugeleza kwamanzi ingaholela ekongeni amanzi okukhulu futhi ifake isandla ekusimeni okujwayelekile kwemikhuba yokunisela yezolimo.
Ngaphezu kokuthuthukisa ukuphathwa kwamanzi, ubuchwepheshe bokulinganisa ukugeleza kwamanzi obuvulekile be-Doppler bungasekela ukusetshenziswa kobuchwepheshe bokunisela ngokunembile. Ngokulinganisa ukugeleza kwamanzi ngokunembile, abalimi bangasebenzisa amasu okunisela ngokunembile aletha inani elifanele lamanzi ezindaweni ezithile zamasimu abo, becabangela izici ezifana nomswakama womhlabathi, izidingo zamanzi ezitshalo kanye nezinguquko zesimo sendawo. Le ndlela yokunisela eqondiwe ayigcini nje ngokulondoloza amanzi kodwa futhi ikhuthaza ukukhula kwezitshalo kanye nesivuno esihle kakhulu.
Ngaphezu kwalokho, idatha eqoqwe kumamitha okugeleza e-Doppler ingahlanganiswa nezinhlelo zokuphatha ukuchelela kanye namathuluzi okusekela izinqumo, okuvumela ukuhlaziywa okuthuthukisiwe kanye nokwenza ngcono izinhlelo zokuchelela. Ngokusebenzisa le ndlela eqhutshwa idatha, abalimi bangenza izinqumo ezinolwazi mayelana nokuthi bazosebenzisa nini futhi kuphi amanzi, becabangela izici ezifana nezimo zezulu, amazinga okuphuma komoya kanye nezigaba zokukhula kwezitshalo. Leli zinga lokunemba nokulawula landisa ukusebenza kahle kwamanzi, ekugcineni kusize ukonga izindleko futhi kwandise umkhiqizo wezolimo.
Ngamafuphi, ubuchwepheshe bokulinganisa ukugeleza kwemisele evulekile ye-Doppler bunamandla amakhulu okuthuthukisa ukusebenza kahle kokunisela kwezolimo kanye nokusimama. Ngokuhlinzeka ngedatha yokugeleza kwamanzi ngesikhathi sangempela, ukuthola nokuxazulula izinkinga zokusebenza, kanye nokusekela imikhuba yokunisela enembile, amamitha okugeleza e-Doppler asiza abalimi ukuthuthukisa ukusetshenziswa kwamanzi, ukonga izinsiza, kanye nokwandisa isivuno sezitshalo. Njengoba isidingo sokuphathwa kwamanzi okuphumelelayo kwezolimo siqhubeka nokukhula, ubuchwepheshe bokulinganisa ukugeleza kwemisele evulekile ye-Doppler buzodlala indima ebalulekile ekushayeleni ushintsho oluhle emkhakheni wezolimo.
