Umzimba wokukhipha amanzi wakhiwe yi-axis yesikulufo enamapuleti okulungisa nokuhamba ahambisanayo, njengoba ububanzi bangaphakathi be-axis yesikulufo bukhulu kunepuleti elihambayo, ipuleti elihambayo lenza ukunyakaza okujikelezayo nge-axis yesikulufo ukuvimbela ukuvaleka. Isikhala esiphakathi kwamapuleti okulungisa nokuhamba siba sincane kakhulu ngokuya lapho kuphuma khona udaka. Ngemva kokuhlushwa kwamandla adonsela phansi, udaka luthuthwa luye ezingxenyeni zokuphelelwa amanzi, lukhipha amanzi ngaphansi kwengcindezi yangaphakathi yepuleti eliphumayo.
