Genetic Algorithms (GAs) application in the field of water resources engineering is of recent origin. Genetic Algorithms is one of the tools, which handles nonlinear optimization problems in an efficient manner. Optimal reservoir operation of reservoir for hydropower production involves constrained nonlinear optimization. The constrained problem is converted into unconstrained problem by using ...

this study explored reading strategy use of tefl ma students when they read academic research articles in english. the purpose of this study was to investigate how this group of readers typically approaches reading academic research articles related to their field of study, and also what they do in reading such research articles. the aim of the present study was bilateral. first, the researcher...

In this research, a deep explosion in the reservoir of a concrete gravity dam has simulated by the coupled Euler –Lagrange finite element method. The validity of explosion hydrodynamics pressure has compared with Taylor empirical formula.  The surface sloshing not considered due to deep explosion. The dam and its retained water excited by detonating large explosive charges in deep water upstrea...

Run-of-the-river hydroelectric dams cause changes in seasonal inundation of the floodplains, and this may cause displacement of semi-aquatic vertebrates present before dam construction. This study evaluated the movement of crocodilians before and after the filling of the Santo Antônio hydroelectric reservoir on the Madeira River in the Brazilian Amazon, which occurred in November 2011. We radio...

abstract turbidity current is one of the most important factors that effect the sediments distribution and also their transportation and release from reservoir. in this study, effects of these currents on sedimentation process in sefidroud dam were simulated by tcm model in 30 years period. comparison between the case of turbidity currents that reach to the dam wall and release from the reservo...

Blocking the natural bi-directional flow in an estuarine system using an artificial dyke has commonly caused serious water quality problems. In the southwestern part of South Korea, a parallel triple-reservoir system was constructed by blocking the mouth of three different rivers (Yeongsan, Okcheon, and Kumja), which were then interconnected using two open channels. This system has experienced ...

Millions of cubic meters of water run out of reach into rivers annually. Artificial recharge of ground water collection of regional drainage water and re-use of it and simplicity in construction shows Wetland (artificial reservoir) as a sustainable local structure. In planning about irrigation and drainage network of Alborz dam in WEAP medium was modeled. For equitable allocation in project lim...

The paper presents a study on developing an optimum reservoir release policy by using ABC algorithm. The decision maker of a reservoir system always needs a guideline to operate the reservoir in an optimal way. Release curves have developed for high, medium and low inflow category that can answer how much water need to be release for a month by observing the reservoir level (storage condition)....

Nowadays, water resource management has been shifted from the construction of new water supply systems to the management and the optimal utilization of the existing ones. In this study, the reservoir operating rules of Doroodzan dam reservoir, located in Fars province, were determined using different methods and the most efficient model was selected. For this purpose, a monthly nonlinear multi-...
