sorry this question far from my specialize

La régionalisation a des objectifs. En fonctions de cela; il y a différentes techniques mathématiques ou autres.

Prenons en exemple:

- pour les Bassins hydrographiques...il y a des critères.

_ pour les élections ; il y a d'autres critères

- .........

it depends upon your topography, if the area is plain then no need to make the regions as there is very less variation and if the region is hilly then u can make micro regions as per the geo-coordinators of different terrians

Respected Sir, May I get the method to regionalize the country climate-wise plus precipitation zones in one map in order to make better planning/budget. For example, If the division is made in five regions (A, B, C, D, E), Let Region A is hot but with heavy rains, Region B is cold with heavy rain, region C is cold with little precipitation, region D is cold with little rain, region E is normal weather without rain. Please, Dr. Sahib, guide me in this regard.

Pour faire une régionalisation, il y a les paramètres techniques, scientifique, mais ne pas oublier les paramètres politiques....

Dr. A. Kettab, please tell me the required parameters and required data for regionalization.

Thanks.

Dr. Kamran

Thank a Lot Mr Keegan Carvalho , Dr. @

Thanks, Drlatief Ahmad for your valuable answer.

I’m afraid the question is outside my expertise range.

On peut prendre par exemple les précipitations. Les Bassins hydrographiques sont définis comme cela.

Vous pouvez associer température et précipitations.

Thanks Dr A. Kettab . May I get any detail for it. Thanks a lot again!

Dans le monde, en particulier en Europe, les pays sont partagés en bassin.

Unsupervised clustering method (e.g., K-Means, SOM) could be also a choice, and it has been widely used. Hoping this helps.

Thanks Mr. Linqiang He and Dr. A. Kettab

Is any good book available for regionalization the area subject to climate?
