Runoff is critically important for humans in their ecological and economic activities; hence, the ability to estimate
the possible runoff change in response to changes in precipitation and temperature is highly desirable. In this article,
two advanced methods are used to evaluate and quantify the relation and the impact of the runoff, precipitation and
temperature in the Litani river in Lebanon. Firstly, the classical regression linear model method showed the relationships
and the correlation between the factors; also, the regression lag linear model was used to evaluate the dependency
of these factors at different times. Secondly, the advanced optimization shuffled complex method is a general method
which can be used during the absence of the nonlinearity data in order to evaluate the impact of the temperature and
precipitation data on the runoff data of the Litani river at different period.
