Izityalo ezinkcenkceshelwayo zinkcenkceshelwa ngokugalela amanzi kumphezulu wosasazo ngokusebenzisa iityhubhu zokuthontsiza okanye iiteyiphu, ngesandla kusetyenziswa ithumbu, izitshizi ezingaphezulu kunye neebhoom okanye ngokugalela amanzi emazantsi enkonkxa ngokunkcenkceshela, okanye ngokusebenzisa indibaniselwano yezi nkonzo. iinkqubo.Izitshizi ezingaphezulu kunye nokunkcenkceshela izandla zinomkhwa "wokumosha" amanzi kunye nokumanzisa amagqabi, oko kwandisa amathuba okuba nezifo kunye nokwenzakala.Iinkqubo zokuthontsiza kunye nezona zisebenza kakuhle kwaye zibonelela ngolawulo olukhulu kumthamo wamanzi asetyenziswayo.Kwakhona, ekubeni amahlamvu engabi manzi kukho ukuncitshiswa kwezifo kunye nokwenzakala.
