Why Use Fuzzy Logic

As an esteem of the eastern thinking, philosophical objects may be raised by logical premises and implications along three basic mental activities, namely, imagination, conceptualization and deep thinking which jointly lead to idea generations [9]. Since the existence of terrestrial life, human beings have interaction with nature, which has provided the basic material in the form of objects and events 

Fuzzy logic has its ingredients similar to the brain that deals with inexact information after the perception and fundamental inspirations about the phenomenon concerned. Fuzzy logicians have the opportunity for dynamic and numerical model free estimators for any engineering event. They are structured numerical estimators. Since, in engineering, estimations and predictions are the most 

Logical assessments require initial mental reasoning for the identification of similarities and differences between various scrap information, and finally, they are established in a systematic way to express the study conditions. Fuzzy logic approach leads to automation and machine intelligence of hydrologic phenomena. 

The fuzzy logic can express all the subjectivity in human thinking and natural linguistic expressions in a comparatively undistorted manner. The foUowing points lead to the necessity of fuzzy logic concepts use in the modeling. 

It is possible to execute the following hydrological processes with the use of fuzzy logic rule and system concepts.
