Reservoir dams are among the main storage systems employed in agriculture for the several past decades. Proper operation of these reservoirs is important for irrigation espe-cially in such arid and semi-arid areas like Iran, and particularly during dry years. A computational framework for reservoir simulation and flood routing is hereby presented. A key aspect of the reservoir simulation is the ease of use by managers and model users. In this paper, an object-oriented toolkit for building computer models for simulation of reservoir operation and flood routing in Boukan reservoir dam is used. The modeling ap-proach taken in this paper is significantly different from that typically employed in the development of water resources planning and management models. The medium in this kind of model provides a graphical object-oriented interface that allows the user(s) to model complex systems without even requiring a profound proficiency in computer pro-gramming. The Object Oriented Programming (OOP) environment chosen to develop the model of Boukan dam reservoir was STELLA Software. The probability of flood occur-enceis also taken into account for a prediction of more accurate results.
