Watershed - fikradda ah, kaas oo ka qayb qaatay daraasadda ee sayniska ee biyaha raaca. Waa maxay nuxurka iyo macnaha of fikradda guud ee sayniska? Waa maxay noocyada watersheds kala duwanaayeen saynisyahano? Jawaabaha su'aalahan - in our article.

Watershed - waa ... Qeexid

On dhulkeenna, tobanaan kun oo webi. Oo mid kasta oo iyaga ka mid ah oo biyo ka meel gaar ah ay u ururiyaan. Watershed - waa line ah khayaali ah barbaro on dhulka. Ka hor inta aan la qeexo nuxurka fikradda this waa in ay yaqaanaan qaar Eray kale. Kuwanu waa labada ra'yi biyaha: Nidaamka webiga iyo berkeddii weysada webiga.

Nidaamka webiga - waa nidaamka biyaha, taas oo ka kooban webiga ugu weyn oo dhan addoommo ay. Under weysada webiga waxaa loogu tala galay in meesha ay ka kaas oo biyaha oo dhan (dusha iyo dhulka hoostiisa labadaba) ururayaa in nidaam webiga gaar ah. Hadda waxaad siin kartaa qeexidda macquul ah oo cad oo lagu qaybsanyahay webiga.

Watershed - line a xadeeyo ah wabiyada deriska ah. In dhulka buuraleyda ah ama buur ah waxaa loogu muujiyey si cad, iyo bannaanka - tirana. In buuraha reer khadadka qaybsanyahay inta badan ay maamulaan weheliyaan fatihi iyo tiixtiix. Xaaladdan oo kale socodka biyaha iyo roobab faray in dhinacyada kala duwan ee calamaada ah (on dhinac oo iska soo horjeeda).

dhulka lagu qaybsanyahay gudahood lagu sheegi karaa si cad in gargaarka. Waxaa intaa dheer, in goobahaas uu line xitaa loo barakacay kartaa in hal jiho ama mid kale muddo ama ku xiran tahay xilli.

Noocyada ugu muhiimsan ee watersheds

Watershed kala ah maddiibadood oo badaha kala duwan ama loo diyaariyey degaanka ee faniinkaba gudaha ah, loo yaqaan qaaradda. Tusaale ahaan, in America, line this waddaa weheliyaan tiixtiix ugu sareeya iyo danbow ka mid ah Cordillera iyo geedka kokaha.

Daraasaddu waxay of watersheds

Baadhitaanka ayaa ka mid ah khadadka Jooloojiyadda caadiga kor ku tilmaamay waa muhiimadda sayniska iyo wax ku ool ah oo weyn. Gaar ahaan marka ay timaado horumarinta firfircoon ee meel juquraafi aadanaha.

Sidaas, marka la dhigaayo buundooyinka, biyo-xireenno ama Quwadda on webiga, kaliya aad u baahan tahay inaad wax fikrad ah oo ku saabsan sida loo mari line qaybsanyahay ee gobolka gaar ah. More muhiimsan, daraasad faahfaahsan watersheds ee qorshaynta ee kaydadka waaweyn. Tani waa lagama maarmaan si ay u si sax ah loo xisaabiyo lacagta ugu badan ee ka iman kara buuxinta kaydka mustaqbalka.
