Kuyerera kwemvura kwakavhurika kunowanikwa muZvisikwa pamwe chete nemuzvivakwa zvakagadzirwa nevanhu. MuZvisikwa, kuyerera kwakadzikama kunoonekwa munzizi huru dziri pedyo nemigero yadzo: semuenzaniso Rwizi rweNile pakati peAlexandria neCairo, Rwizi rweBrisbane muBrisbane. Mvura inoyerera inosangana munzizi dzemakomo, mapopoma enzizi uye mapopoma. Mienzaniso yekare inosanganisira madhaka eRwizi rweNile, mapopoma eZambesi muAfrica nemapopoma eRhine.
Rwizi rweWisconsin nejecha muna Nyamavhuvhu, 1966 - zvichitarisa kumusoro kwerwizi.
Migero yakavhurika yakagadzirwa nevanhu inogona kuva migero yemvura yekudiridza, magetsi nemvura yekunwa, mugero wekutakura zvinhu muzviteshi zvekuchenesa mvura, nzira dzemvura dzine dutu, mamwe matsime everuzhinji, makomba ari pasi pemigwagwa nemigwagwa yezvitima.
Kuyerera kwemvura kwakavhurika kunoonekwa munzvimbo diki pamwe chete nedzinoyerera zvikuru. Semuenzaniso, kudzika kwemvura kunogona kuva pakati pemasendimita mashoma mumiti yekuchenesa mvura uye kupfuura 10 m munzizi huru. Kumhanya kwemvura kunogona kubva pasi pe 0.01 m/s mumvura yakadzikama kusvika pamusoro pe 50 m/s munzira ine mvura yakawanda. Huwandu hwemvura inobuda2 hunogona kubva pa Q ~ 0.001 l/s mumiti yemakemikari kusvika pa Q > 10 000 m3/s munzizi huru kana nzira dzinoyerera. Zvisinei, mumamiriro ese ekuyerera kwemvura, nzvimbo yemvura yakasununguka haizivikanwe kare uye inotsanangurwa nekushandisa misimboti yekuenderera mberi uye simba.
Saka mukukura kuri kuita sainzi netekinoroji nhasi uno, kuvandudzwa kwezvigadzirwa, izvo zvigadzirwa zvemvura zvinoyera mwero wekuyerera kwenzira dzakavhurika zvine hungwaru uye zvakarurama, seizvi:
