background: eutrophication is one of the detrimental environmental problems in water reservoirs dye to the irregular introducing nutrients (phosphorus and nitrogen). this study aimed to explore the eutrophication state of ekbatan reservoir, hamadan, western iran. methods: monthly sampling was conducted during april 2010 to march 2011. seven sampling stations were selected in the various locatio...
In recent years, Aquaculture has an important role to play in The production of animal proteins, employment, and poverty reduction, especially in rural areas. Water supply as a limiting factor in developing countries. Therefore, Multipurpose use of water resources, including, Water use at integrated aquaculture-agriculture farms is a Strategies for Sustainable Development in the world. The aims...
Gotvand olia dam is the highest embankment dam in Iran. this dam is the last dam built on the Karun River before entering khuzestan plain in gotvand area. the main worry of the analyst before the gotvand dam impoundment, has been the dissolution of the anbal salt in the reservoir of the dam and affected the karun water at the bottom of the dam. the aim of this study was checking the effects o...
Background and purpose: The study aimed to investigate the trophic state of Ekbatan Dam Lake. In the current research, the quality of water behind the dam was studied during the months July and January in order to compare the trophic state and zonation of the reservoir in two different seasons (dry and wet). Materials and Methods: 15 sites were selected in different points of Ekbatan Dam Lak...
Windows TM Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of embankment dams. These software components are being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap...
Reservoir sedimentation is a worldwide problem affecting sustainable storage use as well as sediment transport downstream of dams. Various techniques are applied for sediment mitigation, among which, venting of turbidity currents. This paper reviews, discusses and evaluates venting of turbidity currents based on an experimental approach. Data acquisition during the tests is accomplished using f...
Concrete faced rockfill dams (CFRDs) are among the structures that due to their advantages such ease of construction and low execution costs,have attracted more attention nowadays.Due to the fact that during large earthquakes,the hydrodynamic pressure will be large and cannot be ignored,the main purpose of this research is to apply reservoir hydrodynamic pressure of dam reservoir caused by the ...
In this paper we develop a positive calibrated approach to stochastic dynamic programming. Risk aversion, discount rate, and intertemporal substitution preferences of the decision-maker are calibrated by a procedure that minimizes the mean squared error from data on past decisions. We apply this framework to managing stochastic water supplies from Oroville Reservoir, located in Northern Califor...
