Sedimentation in reservoirs is an important issue that should be considered for the reservoirs operation and useful life. In this study, application of the Adaptive Neuro-Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN) in prediction of the sediment release from the bottom outlet using semi-cylinder for different variables was evaluated. Dimensionless parameters such as dimens...

The effect of a plate installation upstream an orifice was investigated as new method for improving the pressurized flushing efficiency. A with three different widths (B T ) installed at four distances (L orifice. According to results, significantly increased efficiency due wake vortices formed up maximum value 11.5 times relative what calculated experiment without same conditions. For best con...

In this study was examined the factors affecting the unwillingness to adopt pressurized irrigation methods among farmers' groups (with different levels of drought) in Ardabil province (Iran). Mixed method (Qualitative – Quantitative paradigm) was used for doing this research. First, by drought zoning of Ardabil province (by SPI method and GIS), three regions included the mild, moderate and seve...

Sixty Ghezel ewes (age 3.5 years) were used to study the effect of different nitrogenous supplements in flushing ration on reproductive performance. Experimental treatments were divided in five groups: group A: urea; group B: soybean meal (SBM); group C: corn gluten meal (CGM); group D: barley grain and group E: control or basal diet (no flushing). The four flushing rations had nearly the same ...

How to increase the efficiency of chemical flushing and decrease the remediation expenses of contaminated soils are two key scientific and technological issues to be solved. Joint chemical flushing was tested and compared with the water-flushing. The joint acid-flushing could effectively remove petroleum hydrocarbons in contaminated aquorizem and the dosage of washing powder as a flushing agent...

9 The Authors devised a novel generic approach to assessing the flushing of the Irish 10 Sea through the determination of spatially distributed residence times and the 11 development of flushing homogeneity curves. Results indicate that flushing of the 12 Irish Sea is both spatially and temporally highly variable. Average residence times 13 of the material introduced in winter may be up to 28% ...
