Mabhenefiti eMadziva Ekugadzira Mukutonga Mafashamo uye Kuchengeta Mvura
Matangi emvura ekugadzira imhando yezvivakwa zvemvura zvakavakwa nevanhu kuti vabate, vachengetedze, uye vadzore kuyerera kwemvura. Munzvimbo dzakawanda, kunyanya dzine mamiriro emvura emwaka, shanduko mukushandiswa kwevhu, uye kuwedzera kwevanhu nekukurumidza, matangi emvura ekugadzira imhinduro yakakosha yekugadzirisa matambudziko maviri makuru: mafashamo munguva yemvura uye kushomeka kwemvura munguva yekusanaya kwemvura. Kuburikidza nekuronga kwakakodzera, matangi anoshanda kwete senzvimbo yekuchengetera mvura chete asiwo sezvishandiso zvekugadzirisa njodzi uye rutsigiro rwezvinodiwa zvakasiyana-siyana zvehupfumi nemagariro evanhu.
Matangi emvura ekugadzira semidziyo yekudzora mafashamo
Chimwe chezvakanakira zviri pachena zvemadhamu ekugadzira ndekukwanisa kwawo kuderedza mafashamo anokonzerwa nekupisa kwemvura. Munguva yemvura, mvura yakawanda inonaya inokonzera kuti mvura ibude munzizi zvakanyanya. Kana mvura iyi ikasadzorwa, mvura inogona kuyerera ichipinda munzvimbo dzekugara, minda yekurima, uye nzvimbo dzeveruzhinji. Madhamu anoshanda se "madhamu enguva pfupi," achidzivirira huwandu hwemvura kana mvura ikabuda munzizi ikawedzera. Nenzira iyi, mvura yaizoyerera nekukurumidza ichidzika inogona kudzorwa kuitira kuti isapfuure huwandu hwemvura inoyerera munzizi uye nzira dzekudonhedza mvura.
Nzira dzekudzora mafashamo mumatangi emvura dzinowanzo sanganisira kudzora magedhi emvura kana nzira dzinorasikira mvura. Kana mvura ichipinda mutangi ichiwedzera, vashandi vematangi vanogona kumisa mvura kwenguva pfupi, zvichideredza kukwirira kwemafashamo. Kana mamiriro emvura ari pasi pemvura akachengeteka, mvura inoburitswa zvishoma nezvishoma. Iyi nzira inonzi kushanda kwetangi remvura kwakavakirwa pamitemo, iyo inoshandisa gwara rehuwandu hwemvura hwakagadziriswa zvichienderana nemwaka uye mamiriro ekunze. Nekutarisira kwakakodzera, matangi anogona kuderedza kuwanda kwemafashamo, kupfupisa nguva yemafashamo, uye kuderedza kukuvara.
Pamusoro pekudzivisa kuyerera kwemvura yakawanda, madhamu anobatsirawo kudzikamisa kuyerera kwemvura munzizi. Nzizi dzine mvura inoyerera ichichinja-chinja zvikuru—yakawanda munguva yemvura, yakaderera zvikuru munguva yemvura—dzinowanzosangana nenjodzi uye kukanganiswa kwehupfumi. Madhamu anogona "kuenzana" nekuchinja-chinja uku, zvichideredza mafashamo akanyanya uye kuchengetedza mvura shoma inoyerera munguva yemvura.
Kuchengeta Mvura Kuti Urambe Uchikwanisa Kutsungirira Munguva Yekuoma
Basa rechipiri rakakoshawo nderekuchengetwa kwemvura. Munzvimbo zhinji, kuwanikwa kwemvura hakuenderane nezvinodiwa nevanhu. Munguva yemvura, mvura yakawanda, asi munguva yemvura, zvinhu zvinodzikira zvakanyanya. Matura ekugadzira anobvumira mvura yakawandisa munguva yemvura kuti ichengetwe kuti ishandiswe munguva yemvura.
Mvura inochengetwa mumatangi inogona kugoverwa kune zvinodiwa zvakasiyana-siyana, zvakaita semvura isina kugadzirwa yemumba, kudiridza kwekurima, zvinodiwa mumaindasitiri, uye kunyange kuchengetedza kuyerera kwenzizi, zvichiita kuti nharaunda igare zvakanaka. Nekuchengetwa kwemvura, nharaunda dzinodzivirirwa zviri nani kubva kunjodzi dzekusanaya kwemvura, kutadza kwezvirimwa, uye kusawirirana kwekushandiswa kwemvura pakati pematunhu. Mukati mehurongwa hwemazuva ano hwekutarisira zviwanikwa zvemvura, matangi anoshanda se "mabhangi emvura" anowedzera kuchengetedzwa kwemvura.
Munyaya yekurima, matangi ekugadzira anokanganisa zvakanyanya kugadzikana kwekugadzirwa. Kudiridza kunobva munzizi dzisina matangi kunowanzo pera munguva yekusanaya kwemvura. Matangi anogona kupa mvura nguva dzose, zvichiwedzera goho rezvirimwa (semuenzaniso, kubva pagoho rimwe chete kusvika pagoho mbiri kana nhatu pagore). Kukanganisa kwacho kuwedzera kwemari inowanikwa nevarimi, kuchengetedzeka kwechikafu, uye kudzikira kwekushaya simba kwehupfumi hwemaruwa.
Mamwe Mabhenefiti: Simba, Kubata Hove, uye Kushanya
Kunyange zvazvo chinangwa chikuru chiri chekudzora mafashamo uye kuchengetwa kwemvura, matangi ekugadzira anowanzo kupa mamwe mabhenefiti. Chimwe chezvibatsiro zvakadaro kugadzira magetsi emvura. Nekushandisa musiyano uripo pakati pemusoro nekufamba kwemvura zvinodzorwa netangi, magetsi anogona kugadzirwa zvakadzikama uye nemhepo shoma. Simba iri rinobatsira kusangana nezvinodiwa nemagetsi emunharaunda uku richideredza kuvimba nemafuta efossil.
Munzvimbo zhinji, madhamu emvura anoshandiswawo pakubata hove dzemvura yakachena kuburikidza nemakeji emvura inoyangarara kana kuburitsa hove dzakakangwa. Kana zvikatarisirwa nenzira inochengetedza nharaunda, mabasa aya anowedzera mapuroteni uye anogadzira mabasa. Uyezve, madhamu ane nzvimbo dzakanaka anogona kugadzirwa senzvimbo dzevashanyi, zvichipa mikana yekufamba nechikepe, kubata hove, mitambo yemumvura, nenzvimbo dzakasvibira dzakavhurika dzenharaunda. Izvi zvichakurudzirawo mabasa ehupfumi emunharaunda, kubva pakubika kusvika pekugara.
Kutarisira Dzimba Dzemvura: Kiyi Yekubudirira
Mabhenefiti edziva rekugadzira haangouyi otomatiki nekuti dhamu rakavakwa. Kubudirira kunoenderana zvakanyanya nekushanda kwaro uye manejimendi yaro. Kudzora huwandu hwedziva kunofanira kugadzirisa zvinangwa zviviri zvinopikisana dzimwe nguva: kupa nzvimbo yakakwana yekutsungirira mafashamo uku uchichengetedza mvura inochengetwa kwenguva yekusanaya kwemvura. Kana dziva rakazara zvakanyanya munguva yekunaya kwemvura, kugona kwaro kuchengetedza mafashamo kunodzikira. Kusiyana neizvi, kana risina mvura yakawanda, mvura inogona kukanganiswa munguva yekusanaya kwemvura.
