Climate changes significantly cause the precipitation deficiency and in turn reduce inflow amount reservoir affecting hydroelectric power generation. The primary objective of this study was to evaluate hydropower generation operation under climate change from Kesem reservoir. Recent Representative Pathway (RCP) scenarios were used impact on Power transformation equation variance scaling approac...

The method of fracturing of oil gas reservoir is considered as an instrumental one for maximizing the yield. Multiple loads in a well fracturing operation may compel tubing string to yield, break and/buckle in a permanent spiral, leading to severe financial deficit. Mathematical models for mechanical analysis of fracturing string in whole fracturing operation are developed on the basis of opera...

This study is focused on developing an integrated optimization-simulation model to develop the operation policies for a multi-purpose reservoir. Objective function of the optimization model is considered to be a linear function of reliability, resiliency, and vulnerability of river-reservoir systems. Genetic Algorithm (GA) is used to solve the optimization model in which the coefficients of the...

construction and operation of dams have two main effects on streams. at first it increases detention time and then leads to thermal stratification. changing of water quality is the result of these effects and the outflow has different physical, chemical and biological characteristics from inflow.in this study thermal regime in proposed bakhtyari reservoir was simulated with ce-qual-w2 model. th...

Data mining technology is applied to extract the water supply operation rules in this study. Five characteristic attributes—reservoir storage water, operation period number, water demand, runoff, and hydrological year—are chosen as the dataset, and these characteristic attributes are applied to build a mapping relation with the optimal operation mode calculated by dynamic programming (DP). A Le...

The capacity planning and operation problem of a multi-purpose water reservoir has been extensively studied in the literature. Optimization techniques, especially linear programming, have been used quite successfully. Although most models are robust enough as planning tools, they fall short of providing an operational policy for the shorter term. In this paper, we consider the operation of a mu...
