Kudiridza kurima kunopa mari inopfuura 70% yemvura yakachena inobviswa pasi rose, asi kushandiswa kwemvura kusina kunaka—kunokonzerwa nekufungidzira, kutarisa kwakapfuura, uye kugoverwa kusina kuenzana—kunoparadza mabhiriyoni emamita ekubikira pagore. Sezvo kushomeka kwemvura kuri kuramba kuchikwira, varimi nevatungamiriri vekurima vanoda maturusi ekutevera, kugadzirisa, uye kuderedza kushandiswa kwemvura yekudiridza. Mamita ekuyerera kwemvura akavhurika, akagadzirirwa kuyera kuyerera kwemvura mumigero isina kumanikidzwa (semuenzaniso, migero, migero, uye migero yekudiridza) yakajairika mukurima, ave mhinduro huru yekuvandudza kuchengetedza mvura mukurima. Nekupa data remvura chaiyo, panguva chaiyo, mamita aya anoshandura kudiridza "kusingaonekwi" kuita tsika inotungamirirwa nedata, achideredza marara uku achidzivirira goho rezvirimwa.
Dambudziko reKudiridza Kusina Kuongororwa
Kudiridza kwekurima kwechinyakare kunowanzoenderana nekufungidzira kwakajeka: varimi vanogona kudiridza minda zvichienderana nenguva (semuenzaniso, "kumhanya kwemugero kwemaawa maviri") kana zviratidzo zvinoonekwa (semuenzaniso, "mirira kusvika ivhu raoma"), pane kuyerera chaiko kana kuti mvura yezvirimwa inoda kuyerera. Izvi zvinotungamira kukusashanda zvakanaka kuviri:
- Kudiridza zvakanyanya: Vasingazive mwero chaiwo wekuyerera kwemvura, varimi vanowanzo shandisa mvura yakawanda kupfuura inonwiwa nezvirimwa. Mvura yakawandisa inoburitsa zvinovaka muviri kubva muvhu, inopedza simba (rekupomba), uye inopedza mvura yakachena yemuno (semuenzaniso, mvura yemumvura kana nzizi).
- Kugoverwa kusina kuenzana: Munzvimbo huru dzekudiridza, kuyerera kwemvura kusingatariswe kunogona kukonzera kuti mimwe minda iwane mvura yakawandisa nepo mimwe ikawana mvura shoma - zvichikanganisa goho uye zviwanikwa zvinoraswa.
Semuenzaniso, murimi anoshandisa mugero usina kutariswa angasaziva kuti chikamu chakavharika chinoderedza kuyerera kwemvura mumunda mumwe, zvichimuita kuti ashandise hurongwa kwenguva yakareba kuti adzore—achizadza mumwe munda nemaune. Mamita ekuyerera kwemvura akavhurika anogadzirisa izvi nekuyera kuyerera kwemvura, achibvisa kufungidzira.
Maitiro Ekuchengetedza Mamita Ekuyerera Kwechiteshi Chekuvhurika
Mamita ekuyerera kwemvura mumigero yakavhurika anoshandisa matekinoroji akadai se ultrasonic, radar, kana weir/flume systems kuyera kuyerera kwemvura mumigero isina kumanikidzwa—yakanakira zvivakwa zvekudiridza zvinotoshandiswa nevarimi. Kukanganisa kwavo pakuchengetedza mvura kunowanikwa munzvimbo nhatu dzakakosha:
1. Kuyera Kuyerera Kwakarurama Kwekudiridza "Saizi Yakakodzera"
Mamita aya anopa ruzivo rwechokwadi rwekuti mvura yakawanda sei iri kuyerera mugwara rega rega kana mumunda. Varimi vanogona kufananidza mwero wekuyerera kwemvura nezvinodiwa nezvirimwa: semuenzaniso, chibage chidiki chingada marita makumi mashanu paminiti pahekita, nepo gorosi rakura richida marita makumi matatu chete. Nekuisa mita yekuyerera kwemvura kuti itange yambiro kana mwero ukadarika kana kuderera pasi pehuwandu hwaunoda, varimi vanodzivisa kudiridza zvakanyanya uye vanoona kuti zvirimwa zvinowana chaizvo zvavanoda. Zvidzidzo zvinoratidza kuti kunyatsojeka uku kunogona kuderedza kushandiswa kwemvura yekudiridza ne15-30% pasina kuderedza goho.
2. Kuona Kubuda Kwemvura Uye Kuvhara Kunomisa Marara
Nzira dzekudiridza nemapaipi zvinowanzo buda mvura, matombo, kana kuvharika—matambudziko asingaonekwe pasina kutariswa. Mita yekuyerera kwemvura yakavhurika inoratidza kusarongeka: kudonha kamwe kamwe kwemvura kunogona kuratidza kuvharika (semuenzaniso, marara mugomba), nepo kuwedzera kusingatarisirwi kunogona kuratidza kudonha kwemvura (semuenzaniso, mugero wakatsemuka). Nekubata matambudziko aya nekukurumidza, varimi vanogadzirisa matambudziko nekukurumidza, vachidzivirira zviuru zvemarita emvura kuti asaparadzwe. Semuenzaniso, kudonha kudiki mumugero kunogona kutambisa marita anosvika zviuru gumi pazuva—chimwe chinhu icho meter yekuyerera kwemvura ingaona mukati memaawa.
3. Kutevera Data Kuti Ushande Nenguva Refu
Mazhinji emamita ekuyerera kwemvura emazuva ano anochengetedza ruzivo rwekare (semuenzaniso, huwandu hwemvura inoyerera zuva nezuva kana vhiki nevhiki) uye anosanganiswa nemadashboard ari nyore. Varimi vanogona kuongorora ruzivo urwu kuti vaone maitiro: "Munda A unoshandisa mvura yakawanda here neMuvhuro?" kana kuti "Dutu remwedzi wapfuura rakaderedza kuda kwedu kudiridza here?" Nekufamba kwenguva, ruzivo urwu runobatsira kunatsiridza hurongwa hwekudiridza—semuenzaniso, kuderedza kuyerera kwemvura munguva dzemvura kana kugadzirisa mwero wezvirimwa pazvinokura. Inotsigirawo kutevedzera mitemo yemvura yemuno, iyo inowedzera kuda kuti varimi vatevere uye vataure nezvekushandiswa kwemvura.
Mhedzisiro Yechokwadi Pasirose: Nyaya Yemapurazi Madiki
Kunyangwe varimi vadiki vanobatsirwa nemamita ekuyerera kwemvura akavhurika. Munzvimbo dzakadai seUS Great Plains kana India's Punjab, uko huwandu hwemvura iri pasi pevhu huri kudzikira nekukurumidza, varimi vanoshandisa mita idzi vakashuma kuchengetedza mvura zvakanyanya. Semuenzaniso, purazi remhuri muNebraska rakaisa mita dzekuyerera dzemagetsi dzakavhurika mumigero yaro yekudiridza uye rakaderedza kushandiswa kwemvura ne22% mumwaka mumwe chete wekurima—richichengetedza mari pamari yekupomba uku richibatsira kuchengetedza Ogallala Aquifer. MuIndia, mapoka ekudiridza anoshandisa mita dzekuyerera kupatsanura mvura zvakaenzana pakati pevarimi, zvichideredza kusawirirana uye kuderedza marara ne18%.
Mhedziso
Mamita ekuyerera kwemvura akavhurika haasi ekungoyera chete—anosimudzira kurima kunoenderera mberi. Nekushandura nzira dzekudiridza dzisina kujeka kuita sarudzo dzakarurama, dzinotungamirirwa nedata, dzinoderedza marara emvura, dzinochengetedza zviwanikwa zvemvura yakachena, uye dzinoona kuti zvirimwa zvinowana mvura yazvinoda kuti zvikure. Sezvo kushomeka kwemvura pasi rose kuri kuwedzera, mita idzi dzichava chishandiso chakakosha kuvarimi vakazvipira kuyera kubereka nekuchengetedza—kuchengetedza chikafu nemvura yeramangwana kwezvizvarwa nezvizvarwa.
