Comparison of Ant Colony, Elite Ant system and Maximum – Minimum Ant system Algorithms for Optimizing Coefficients of Sediment Rating Curve (Case Study: Sistan River)

By far, different models for determining the relationship between the flow rate  and amount of precipitation have been developed. many models are based on regression models with limited assumptions. one of the most common methods for estimating  sediment of rivers is sediment rating curve. for better estimation of the amount of sediment based of sediment curve  rating equation, it is possible to optimize its coefficients. this estimation of flow rate , which is much easier than measuring  sediment rate, provides more prices and accurate estimation of sediment rate.
