Ithangi Lokugcina Amanzi Emvula Lesikhungo Sedatha: Ukubamba, Ukugcina Nokusebenzisa Kabusha
Ithangi lokugcina amanzi emvula lesikhungo sedatha likalwa ngokuvunwa kwendawo yokubamba uma kuqhathaniswa nokushintshashintsha kwemvula ngezikhathi, hhayi ngendawo yophahla kuphela, futhi amanzi abanjiwe ayelashwa aze afinyelele izinga lomsebenzi ngaphambi kokusetshenziswa. Imisebenzi engokoqobo iwukugcwaliswa kokupholisa nokusetshenziswa okungewona awokuphuza; inani liwukuhlinzeka okwazi ngokwesimo sezulu okususa ukudonswa kukamasipala futhi kuthuthukisa ukulingana kwamanzi esiza, okulinganiselwe ukushintshashintsha kokubamba kanye nezindleko zokwelashwa.
Isingeniso
Ukubuthwa kwamanzi emvula endaweni yesikhungo sedatha kuqala ngokubona okulula: uphahla olukhulu nendawo eqinile kukhipha amanzi okwamanje athunyelwa emseleni, kuyilapho isitshalo sokupholisa sithatha amanzi kamasipala esingawanciphisa ngokwengxenye. Ukubamba leyo mvula kuguqula ukukhishwa kube ukuhlinzekwa, futhi ithangi liyimpahla eyenza ukubamba kusebenziseke, libambe imvula eguquguqukayo njengesivikelo isitshalo esingathatha kuso.
Le ndatshana ihamba ngohlu lokubamba nokugcina ngasohlangothini lomthengi. Ihlanganisa ukuthi ingakanani amanzi indawo engawabamba ngempela, ukuthi umthamo wokugcina ubekwa kanjani ngokuhambisana nokushintsha kwezinkathi zemvula, ukuthi uhlelo lokuqoqa nethangi kukalwa kanjani, ukwelashwa amanzi abuthiwe ayidingayo ukuze afeze umsebenzi, imisebenzi yini engawasebenzisa ngempela, isithombe sezindleko nokunakekela, ukuthi umthamo obuthiwe ubikwa kanjani, kanye nemikhawulo nokuphikisana okunquma ukuthi uhlelo lukufanele yini ukwakhiwa.
Ingakanani amanzi indawo engawabamba
Ukubanjwa kuqala ngesizinda: indawo yophahla kanye nanoma iyiphi indawo eqinile edonswa yiselwa ohlelweni, ngayinye iphindaphindwa nge-coefficient yayo yokugeleza kwamanzi kanye nokujula kwemvula, ukuze kunikeze umkhiqizo wevolumu. Ubudlelwano olunengqondo bokuthi umkhiqizo ulingana nendawo yesizinda ephindaphindwe nge-coefficient ephindaphindwe ngemvula, futhi uphahla lubusa ngoba lukhulu, lune-coefficient ephezulu futhi, njengoba lungaphezu kokuxhumana nomhlabathi, luhlala lihlanzekile. Indawo eqinile yengeza ivolumu kodwa yengeza umthwalo.
Inombolo ebalulekile ayiyona isamba sonyaka owodwa kuphela kodwa ukusatshalaliswa kwayo phakathi nonyaka, ngoba uhlelo olulinganiswe ngokwesilinganiso sonyaka luthola okuncane okubalulekile uma imvula ina ngeziphepho ezimbalwa ithangi ligcwala. Ngakho-ke ukuthunjwa kwamanzi kuvezwa njengejika lokukhiqiza elihambisana nokuvama kwemvula, okuthathwa kulo ukuthunjwa okusetshenzisekayo, ngemva kokuhanjiswa kwamanzi okuqala nokulahlekelwa. Indawo esifundeni semvula eningi ithola amanzi amaningi kodwa ngokuguquguqukayo okukhulu; ukuthunjwa kwendawo eyomile kuncane futhi kufanele kulinganiswe ngokwethembeka ngokushoda kwenkathi eyomile okungeke kukwazi ukukukhokhela.
