Cov transmissivity ntawm lub aquifer yog ib qho kev ntsuas ntawm qhov ntau ntawm cov dej uas tus dej hiav txwv muaj peev xwm kis tau kab rov tav thiab yuav tsum tsis txhob totaub nrog transmittance, ib qho kev ntsuas siv hauv optics. Ib dej hiav txwv yog ib txheej ntawm pob zeb los yog unconsolidated sediments uas tuaj yeem tso dej rau lub caij nplooj ntoos hlav los yog qhov dej.
Ua raws li qhov no saib, transmissivity hauv hydrology yog dab tsi?
Kev sib kis yog tus nqi ntws nyob rau hauv ib chav tsev hydraulic gradient los ntawm ib chav tsev dav ntawm aquifer ntawm thickness m (qhib B). Daim duab los ntawm Ferris et al. (1962). Hydraulic conductivity yog ib qho kev ntsuas ntawm cov khoom muaj peev xwm xa dej.
Tsis tas li ntawd, qhov unit ntawm transmissivity yog dab tsi? Kev sib kis Nws yog sib npaug rau cov khoom ntawm lub aquifer thickness (m) thiab hydraulic conductivity (K) thiab nws tau piav nyob rau hauv units ntawm gpd / ft (gallons ib hnub ib ko taw ntawm aquifer thickness).
Ib yam li ntawd ib tug yuav nug, dab tsi yog transmissibility ntawm aquifer?
Kev kis tau (lossis transmissivity) yog ib yam khoom muaj feem xyuam nrog hydraulic conductivity uas piav qhia txog lub peev xwm ntawm ib chav dej tshwj xeeb ntawm ib qho tuab, xws li dej hiav txwv , xa dej.
Dab tsi yog qhov cia coefficient ntawm aquifer?
Storativity lub cia coefficient yog qhov ntim ntawm cov dej tso tawm los ntawm khaws cia per unit poob nyob rau hauv hydraulic lub taub hau nyob rau hauv lub dej hiav txwv , per unit cheeb tsam ntawm lub dej hiav txwv . Storativity yog ib tug dimensionless kom muaj nuj nqis, thiab yog ib txwm ntau dua 0.

Kev tshawb fawb txog kev muaj peev xwm yog dab tsi yog dab tsi txawv ntawm nws?
Hom Feasibility. Ntau hom kev ua tau zoo uas feem ntau suav nrog suav nrog kev ua tau zoo, kev ua haujlwm ua tau zoo, thiab kev ua lag luam nyiaj txiag. Kev ua haujlwm muaj peev xwm txheeb xyuas qhov uas yuav tsum tau ua software ua cov kauj ruam los daws teeb meem kev lag luam thiab cov neeg siv khoom xav tau
Congress ntawm Vienna yog dab tsi thiab qhov tshwm sim yog dab tsi?
Cov txiaj ntsig ntawm Congress ntawm Vienna Fab Kis rov qab thaj chaw tau txais los ntawm Napoleon los ntawm 1795 - 1810. Russia txuas ntxiv nws lub hwj chim thiab tau txais kev ywj pheej ntawm Poland thiab Finland. Austria, ib yam nkaus, tau nthuav nws thaj chaw
Dab tsi txaus ntshai zoo kawg li nws yog qhov peb yuav tsum tau khawb trenches thiab sim cov roj npog qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob hauv lub tebchaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi?
Qhov txaus ntshai npaum li cas, zoo heev, zoo kawg yog tias peb yuav tsum tau khawb trenches thiab sim roj-qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob rau hauv ib lub teb chaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi. Nws zoo nkaus li tseem tsis yooj yim dua tias kev sib cav uas twb tau hais tseg hauv txoj cai yuav tsum yog kev ua tsov rog
Dab tsi yog qhov teeb meem nrog Ogallala Aquifer?
Windmills tsuas tuaj yeem tso dej ntau heev, uas txwv tsis pub cov neeg ua liaj ua teb av tuaj yeem tso rau hauv kev tsim khoom. Thiab Ogallala cov xuab zeb thiab pob zeb muaj pes tsawg leeg ua rau qis qis qis ntawm cov dej ntws los rov ua dua nws, txawm tias nyob rau lub caij ntub dej
