Prediction of water quality index in free surface constructed wetlands

Water quality and its effects on human life have become one of the major concerns in aquatic ecosystems. The water quality index (WQI) is defined as a parameter to interpret water-monitoring data and clarify the quality of water. In this study, the gene expression programming (GEP) and artificial neural networks (ANNs)...

Temporal variation of clear-water scour at compound Abutments

Most of actual abutments in rivers are built on foundation, while there is limited number of study available on the effects of the foundation on the local scour . In this study, temporal variation of local scour around compound abutment was investigated experimentally under clear-water conditions. The results showed th...

Predicting Scour at River Bridge Abutments over Time

Good prediction of scour depth over time is essential for the design of river bridge foundations. In this study, two empirical models are developed to predict the temporal variation of local scour at uniform-section bridge abutments and those with enlarged bases, known as compound abutments. The concepts of the princip...

Scouring around abutments and pier is a significant problem for bridges failure. The main objective of this study was the estimation of a predictor of time to equilibrium for long abutments (y/L 1) on the basis of Genetic programming (GP). An important number of experiments with long-lasting were used for GP modeling t...
