Ndi kusiyana lowland mitsinje m'phirimo chiyani? makhalidwe poyerekeza

Mtsinje - ndiwo madzi akumwa anthu. kufunika sangathe saganizira. Mitsinje monga mitsempha madzi, yomwe ili m'malire a dziko lonse pa dziko.

Mitsinje yagawidwa kukula (yaing'ono, sing'anga lalikulu) ndi gulu topographic. Kuti ndi mtunda umene utuluke mtsinje, mitsinje yonse ya dziko anawagawa mitundu iwiri yosiyana ya matupi madzi. ndi kusiyana lowland mitsinje m'phirimo Kodi, mungathe kuwona kuchokera mfundo m'nkhani ino. Ena madzi a mtundu wosanganiza: iwo akhoza anachita ndi mtundu umodzi wa mtunda, ndipo mosiyana.

Mitsinje Mitundu: tanthauzo

M'zigwa mtsinje - madzi amene ali wodekha, wofatsa madzi, chigwa lonse ndipo umayenda mwa chigwa, kapena ndi lathyathyathya mtunda.

Mountain Mtsinje - mtsinje likuyenderera mu chigwa lopapatiza kwambiri, ali mofulumira ndi chipwirikiti otaya, akudutsa mu mpumulo phiri.

Kumasulira bwino kwambiri zimene ndi chigwa cha mtsinje ndi m'phirimo, kodi pali kusiyana pakati pa iwo akhoza kuwerenga m'munsimu.

gwero

Gwero lowland mitsinje amakhala nyanja, Madamu, magwero pansi; pamene phiri - ali kunayambira ku mapiri, m'madera chisanu kapena ayezi.

mitsinje

Mphamvu lowland mitsinje makamaka osokonezeka, ndi mwayi chisanu. Kusefukira iwo akuyamba m'chaka. Zapakati pa masiku 15 mwezi 1. Pambuyo osefukira, madzi madontho, kufika msinkhu wake wotsikitsitsa, wotchedwa nthawi otsika madzi. Kuyankhula za kusiyana m'chipululu cha mtsinje pa phiri, ndi kunena kuti amatunga zina zazing'ono, panopa pang'ono mu wolimbikitsa wa dziko, ndi chuma kuti ziume mu chirimwe. Koma ndi autumn, ndi nthawi chigumula, pakubwerera iwo ku boma lakale. M'phiri mitsinje khalidwe chosiyana. Ali ndi nthenda zonse, konse youma, ndi yozizira mwina amaundana kwathunthu. Iwo kudya mtsinje makamaka chifukwa cha mpweya (mvula). Nambala pazipita ndi m'chilimwe, chifukwa mu nthawi ino phiri mitsinje akhoza kusefukira magombe. Mlingo wa madzi m'nyengo yozizira yafupika ngati kuli kotheka, ndi kupeza khalidwe bata.

madzi kutentha

mitsinje m'zigwa ndi m'mapiri (kusiyana pakati pawo osati zokhazo i pamwambapa) ndi magulu a kutentha madzi. Iye madzi otsika pafupi pamwamba, nthawi zonse otsika, madzi nkomwe konzekera masana. Mu mitsinje chapamwamba phiri, ikakhala apamwamba, kutentha ayanjane + 2 ° C. Madzi boma lowland mitsinje zimasiyanasiyana pa chaka, malingana ndi mtundu wa nyengo. Nthawi zambiri, ngati mtsinje m'nyengo yozizira ozizira kwambiri, nthawi zina kuzizira pamwamba, kudzera magawo atatu: yozizira koopsa, ayezi ndi autopsy. Mu chilimwe, kutentha mmenemo limatuluka kwambiri.

mtsinje chigwa

Kupitiriza kupereka mauthenga pa kusiyana m'chipululu cha mtsinje pa phiri, m'pofunika kuti anthu amvetse kuti chikhalidwe cha pansi pa posungira, yotsika kuchokera Kumwamba, ndi azidzipereka chikoka mtunda. utuluke madzi ndi wandiweyani, miyala ndi m'goli pansi, ndi gombe pafupifupi nthawi yodziwika ndi chikhalidwe miyala ndi mbadwa phompho. Kutiumba pansi pa phiri mtsinje chigwa - V woboola pakati, nthawi zambiri. Njira zomwezo zambiri yopapatiza, alibe yotakata lonse m'litali. nthawi iyi chimadaliranso otaya mathamangidwe ndi mbali ya ndingaliro ya posungira. M'zigwa mitsinje ndi kunena lonse zigwa ake, osaya kuya ndi otsetsereka otsika. Kama wa chotero mtsinje zambiri chikhalidwe tortuous, ndi pansi - silty (clayey nthawi zina kumachitika ndi malo mchenga). Kawirikawiri miyala kunsi kwa chigwa zimachokeradi ngati mtsinje zigwa ali zopinga kapena shoals, iwo ankaimira miyala mchenga. meanders Large amatchedwa meanders (anaŵerama). Mbali wamba phiri lowland mitsinje: akhale pamakomo, amene kwambiri kulimbikitsa mlingo otaya. Iwo akhoza kupangidwa pamene watercourse ndi ili pa thanthwe molimba (zitunda, nsanja).

otaya mathamangidwe

An nuance zofunika funso kusiyana pakati pa zigwa za mtsinje pa phiri, adzakhala chikhalidwe cha otaya lapansi. Madamu anakonza pa mfundo ndi kudya otaya, pafupifupi ndalama otaya akhoza kufika mtengo wa 6 m / s. M'madera pafupi mathithi, ndi kayendedwe ka madzi zina kuonjezera. Mlingo wa otaya phiri mtsinje zimatengera pa mlingo ndingaliro. The apamwamba a njingayo, liwiro otaya madzi. M'zigwa mitsinje ndi bata kulowerera. kochokera kwawo zili pa okwera pang'ono, kotero otsetsereka waung'ono.

The magwiritsidwe chuma mitsinje

mitsinje m'zigwa ndi phiri mitsinje si mofanana ntchito mu dera zachuma. Pa nkhani imeneyi, gawo loyamba ndi yapambana kwambiri. Choyamba, nthawi zambiri iwo ali waukulu phiri mitsinje aloyi ndi kovuta (kupatula okhawo masewera kwambiri tinganene kuti). mitsinje m'zigwa ndi chuma cha n'kupanga ankadziwana lonse pa confluence a nyanja, kapena nyanja. Amadziwika kuti nthaka m'dera limeneli ndi lachonde kwambiri. Mu madzi awo ichthyofauna kuposa mu mitsinje phiri. Pa nthawi imeneyi, iwo ali ndi zotsatira zazikulu kutentha madzi ndi ndalama otaya. Ndipo mawu a ntchito zokopa alendo komanso zosangalatsa mitsinje m'zigwa ndi zambiri otukuka.
