الملخص
The aim of this research is invention probabilistic approach to analyze the recession curve for mean monthly inflows to lakes of Dokan dam at Lesser Zab river and Derbendikan dam at the Diyalah river by dividing the recession curve to many class interval and finding the mathematical equations which controls each class interval by using finite mathematics, and using Markov chain to calculated the transition probability matrix for the classes intervals. A computer program in Visual basic language with visual application interface in Excel software which be developed to generate recession curve. The results indicated that recession curve consist of five class intervals and each class interval have a power regression equation, the statistical analysis indicated a good confidence to use a computer program to generate the recession curve because that average of relative percentage error wasn’t greater than 8 % for Dokan dam and 9% for Derbendikan dam.
