Yuav ua li cas yog unit hydrograph theory?
Lub luag haujlwm ntawm chav tsev hydrograph txoj kev xav hauv cov txheej txheem kev kwv yees dej nyab yog muab kev kwv yees ntawm cov kwj dej uas tshwm sim los ntawm cov nyiaj los nag. Ib chav tsev hydrograph qhia tau hais tias qhov kev hloov pauv ntawm lub sijhawm ntawm kev ntws, lossis kev tso tawm, ib feem ntau ntawm cov nag lossis daus.
Yuav ua li cas hydrograph muab tau?
Los ntawm txhais, Unit Hydrograph yog cov dej ntws ncaj qha los ntawm chav tsev qhov tob ntawm cov dej nag. Yog li, cov kev tswj hwm ntawm qhov xav tau UH tuaj yeem yooj yim tau los ntawm faib cov haujlwm ntawm Direct Runoff Hydrograph los ntawm qhov sib npaug ntawm qhov tob ntawm tag nrho cov dej ntws ncaj qharaws li qhia hauv qab no.
Yuav ua li cas hydrograph siv rau?
Unit hydrographs yog siv los kwv yees dej nyab hydrographs los ntawm kev muab txhua qhov kev tswj hwm ntawm chav tsev hydrograph los ntawm qhov ntim ntawm cov dej ntws. Lub tsevhydrograph txoj kev xav yog ua raws li lub hauv paus ntsiab lus ntawm proportionality, xws li qhov tso tawm txawv ncaj qha nrog qhov tob tob.
