Kuhlanganiswe namamodeli wezolimo we-hydrological, le datha yokulinganisa yesikhathi sangempela ingase futhi isekele izinqumo zokunisela ezihlakaniphile ukuze kuzuzwe umgomo wokongiwa kwamanzi kanye nokwanda kokukhiqiza.
Ukuqapha ukugeleza kwemvelo kungolunye uhlelo olusha lokugeleza kwe-radar ephathwayo. Ngosizo lwale mishini, iminyango yokuvikela imvelo ingaqinisekisa ukuthi ukugeleza kwemvelo okukhishelwa iziteshi eziphehla ugesi ngamanzi kuyahlangabezana yini nezidingo, ihlole izimo ze-hydrological zezindawo ezivikelekile zamaxhaphozi, futhi iqaphe imiphumela yokubuyiselwa kwemvelo emifuleni, njll. Phakathi kwalezi zicelo, ukuphatheka kanye nezici zokulinganisa ngokushesha zezinto zokusebenza zibaluleke kakhulu. Abacwaningi bangaqedela uphenyo olukhulu nolunamaphuzu amaningi ngesikhathi esifushane futhi bakhe amamephu anemininingwane wokusabalalisa indawo ye-hydrological. Kwezinye izindawo ezizwelayo kwemvelo, ukuthintana okuqondile kwezinto zokusebenza nemithombo yamanzi kukhawulelwe. Kodwa-ke, ukulinganisa kwe-radar okungaxhunywanga kuhlangabezana ngokugcwele nezidingo ezinjalo zokuvikela imvelo futhi sekuyithuluzi elikahle locwaningo lwemvelo.
