Kuputika kwedutu ndiko kunyanya kukwira kwemafashamo. Inoumbwa kana dzimwe mhepo dzichitsvaira mukati menyika panguva yemvura zhinji. Somugumisiro, mvura inokwira kunyange kupfuura yakajairika.
Kana dutu rikasunda mvura yakananga kumahombekombe uye ikapindawo mugungwa kana panoyerera mvura, inokwira pamusoro penguva dzose ipapo. Kana mvura yakakwira inopfuura mita imwe nehafu yakakwirira kupfuura iyo inorevesa mafungu emvura, inonzi dutu remhepo. Kubva pamamita maviri nehafu imwe inotaura nezvekuputika kukuru kwemhepo. Kana mvura iri imwe mita yakakwirira, inodaidzwa kunzi mhepo ine simba zvikuru. Madutu emvura anopisa anoitika kakawanda pagore, madutu makuru anonaya makore mashoma oga oga.
Kunyanya kurwiswa kwedutu kwakanyanya kunoitika kana dutu racho rinogara kwenguva yakareba. Kana ikagara kune akati wandei akakwira uye akaderera mafungu emvura, mvura inogona kungodzokera zvishoma kumashure pamvura yakadzika. Pamafungu anotevera akakwirira, inomhanya zvakatokwira kupfuura pane yapfuura.
Ikoku kwakanga kwakadaro, somuenzaniso, nokunaya kwedutu kwaFebruary 1962. Rinozivikanwawo se“Mafashamo eHamburg” nemhaka yokuti makanga mune kuvadziko huru zvikuru nenzufu dzakawanda muHamburg. Panguva iyoyo, mwero wemvura wemamita mashanu uye masendimita makumi manomwe pamusoro zvinoreva mvura yakakwirira yakayerwa. Mushure memafashamo aya, madhayi akasimudzwa kwese kwese, zvekuti gare gare madutu akawanda akanyanya kana akakwira haana kumbokuvadza.
Mhenderekedzo yeNorth Sea muchimiro chayo chazvino yakagadzirwawo nedutu remhepo zhinji. Gungwa rakazadza nzvimbo dzakawanda dzepanyika. Murume akatorazve uye akadzivirira nyika kuburikidza nemadhaini. Pasina madhishi, nzvimbo huru dzekuchamhembe kweGermany neNetherlands dzaizofashukira. Nekuda kwekushanduka kwemamiriro ekunze, masayendisiti anotarisira kuti mvura yemugungwa icharamba ichikwira. Izvi zvinoreva kuti kunyange madutu akakwirira achaitika mune ramangwana. Naizvozvo marevhi anofanira kukwidziridzwa zvakanyanya, kana kuti vanhu vachafanira kusiya chikamu chenyika.
