There is no such word as featurizes, the word you are looking for is 'features'.

"THE Soan River Basin FEATURES the Pot War Plateau." You must put "the" before "Soan River Basin" because it is a proper noun and a definite place. In English physical locations must have "a" or "the." "We're going to A mountain." "I saw THE Empire State Building." "The" is appropriate in your sentence because "a" would mean there are many different "Pot River Basins." "Featurizes" is a great guess at an English word but not correct. The verb you are looking for is "features" which means "to make featured." BUT you are correct that the suffix "izes" is used in the same way in many other english words such as "collectivizes" or "satirizes." Keep it up!
