Madhamu emhando yehydropower zviteshi zvinonyanya kureva zviteshi zvemagetsi zvinovaka zvivakwa zvinochengeta mvura murwizi kuti zvigadzire dhamu, zvinonangisa mvura yechisikigo kusimudza mwero wemvura, uye kushandisa musiyano wemusoro kugadzira magetsi. Chinhu chikuru ndechekuti dhamu negwenya remagetsi emvura zvakanangana muchikamu cherwizi rupfupi.
Zviteshi zvemhando yedhamu remagetsi emvura zvinowanzo sanganisira zvivakwa zvinochengeta mvura, zvimiro zvinorasa mvura, pombi dzekumanikidza, zvidyarwa zvemagetsi, maturbine, majenareta uye midziyo yekuwedzera. Zviteshi zvemagetsi mazhinji zvine madhamu sezvivakwa zvinochengeta mvura zviteshi zvemagetsi emagetsi epakati-pamusoro-soro, uye mazhinji emagetsi emagetsi ane magedhi sezvivakwa zvinochengetedza mvura zviteshi zvemagetsi mashoma. Kana musoro wemvura usina kukwirira uye rwizi rwakafara, simiti yemagetsi inowanzoshandiswa sechikamu chekugadzirisa mvura. Iyi mhando yehydropower station inodaidzwa zvakare kuti riverbed hydropower station, iri zvakare dhamu-mhando hydropower station.
Zvichienderana nenzvimbo yedhamu negwenya remagetsi emvura, zviteshi zvemhando yemadhamu zvinogona kukamurwa kuita mapoka maviri: rudzi rwemadhamu nerwizi. Chigadzirwa chemagetsi chemhando yedhamu chakarongedzerwa kudivi rezasi kwedhamu, uye mvura inotsauswa nemupombi yekumanikidza kugadzira magetsi. Chirimwa pachacho hachitakuri kukwira kwemvura kukwira. Imba yemagetsi, dhamu, spillway uye zvimwe zvivakwa zve riverbed hydropower station zvese zvakavakwa murwizi. Iwo chikamu chechimiro chekuchengetedza mvura uye anotakura kukwira kwemvura. Kurongeka kwakadaro kunobatsira kuchengetedza mari yose yeprojekti.
Dhamu rechiteshi chemagetsi chedhamu rinowanzova pamusoro. Kutanga, musoro wepamusoro unoshandiswa kuwedzera simba rakaiswa rechiteshi chemagetsi, chinogona kunyatsoenderana nepamusoro pepamusoro pezvinodiwa zvemagetsi emagetsi; chechipiri, pane dhamu guru rinokwanisa kugadzirisa kuyerera kwepamusoro-soro kuderedza kudzvinyirira kwekutonga mafashamo erwizi rwezasi; chechitatu, mabhenefiti akazara anonyanya kukosha. Zvakaipa ndezvekuti kurasikirwa nemafashamu munzvimbo yedhamu kunowedzera uye kutamiswa uye kugariswa patsva kwevagari vemumaguta nekumaruwa kwakaoma. Naizvozvo, dhamu-kumashure kwehydropower zviteshi zvine madhamu marefu uye madhamu mahombe anonyanya kuvakwa mumipata yemakomo marefu, nzvimbo dzine mvura yakakura inoyerera uye madiki mafashama.
Mazhinji emadhamu-kuseri kwe hydropower zviteshi zvakavakwa munyika zvakanangana munyika yangu. Yekutanga iTatu Gorges Hydropower Station, ine huwandu hwakaiswa hunosvika 22.5 miriyoni kilowatts. Pamusoro pemabhenefiti makuru ekugadzirwa kwemagetsi, iyo Three Gorges Hydropower Station zvakare ine mabhenefiti akazara ekuona mafashama ari pakati nepakati perwizi rweYangtze, kuvandudza mafambiro uye mashandisirwo emvura, uye inonzi "midziyo inorema yenyika."
