theorist adopted the name from a Latin word “fractus”, meaning a stone crushed in an irregular way ( Mandelbrot 1992 : 52). He regarded geometry as a means of describing a part of the complex nature. In fact, he was looking for a way to detect the hidden forces shaping natural forms and to recreate these forms using those forces ( Mandelbrot 1992 : 52) ( Figure 1 ). Fig. 1 Types of fractals: fractals generated with repetitive operations. According to Lorenz (2003) , these fractals are based on the relationship between mathematics and nature, in which the basic form is

compared to the low-frequency high-magnitude events of the predam phase. The flood frequency started rising continuously as of 1985. The flood frequency doubled (n=15 to 29) during 1990–2010. In brief, though the dams have moderated the flood peak, they have extended the flow duration. The third is related to the anthropogenic sediment flux. Stone quarrying and stone crushing are the dominant anthropogenic inputs that control both the long profile and cross profile of the river which induces the flood. The stone crushing centre produces a huge quantity of stone chips. A
