Economic and financial assessment of the consequences of runoff forecast in dam and hydropower projects (Case study: Karun 4 and Rudbar Lorestan dams and power plants

Increasing energy demand has made improving the management of resource utilization and energy inevitable. The purpose of this article is to compare the power generation of two power plants of Karun 4 and Rudbar dams in the period of 1397-98 in two cases with flood forecasting and warning without applying and paying attention to flood warning and finally estimating economic benefits and revenues. It is a prediction of the use of this system. Flood forecasting and warning systems are among the non-structural methods of flood management that in combination with structural methods can increase the efficiency of flood management. This system timely warnings through planning and management of dam reservoir operation, enables the creation of broad benefits in reducing flood damage lands. In addition to these benefits, another part of the positive effects of these systems is the increase in electricity production in hydropower plants. The results of this study show that the amount of electricity generation in the power plants of dams in the state of flood warning activity by increasing the release from the turbines of power plants before the flood and preventing overflow, 3.9 and 4.8% more than Flood alert mode is desired during the annual interval.
