Abstract
Most of the rivers which originate from Zagros Mountains are considered as the permanent rivers of the country. This permanence has caused the growth of some river basins during the Fourth Period being considered as normal and natural (oberlander, 1965). Something which should be remembered about the domestic base surfaces in the Middle Zagros is the ever present changes which have happened in the Quaternary Period. Most of the domestic base surfaces in this area have embedded hydrologic changes in the form of river-terraces during the Fourth period (Eivazi, 1997). Considering the level changes in the domestic rivers of the country as an evidence of climatic changes of the Fourth Period, lack of those evidences in Task river which is the base surface of Kour river , should be considered as unnatural.
Key words: neurological system, hydrologic behavior, Kour River, geoneurotic system.
